5	Cedar Fever	Insomnia, sexual drive and hair loss which I've never experienced before. I hope they both come back as I'm donating the rest of my prescription to the garbage.	While this has really worked in helping relieve my allergies I don't believe that the benifits outweigh the side effects. I'm going off Alegra D and back to just dealing with the allergies.	M	48	30 days		2/3/2010
3	congestion, runny nose, cough	a little insomnia, hyperactivity, A BLOODY NOSE THAT LASTED ALL NIGHT.	i have not had a bloody nose since i was about 5. Now im 18 and this is the worst one of my life. im actually waiting to go to the hospital right now because its 8am and the bleeding hasnt stopped since about midnight last night.	M	18	3 days		1/8/2010
3	Nasal passages swell shut Sinusitis	10 years ago I thought CLARITIN-D was a miracle drug, and it still might be. I was taking CLARITIN-D for the past ten years up till then I had a sinus infection every 3 months. I stopped taking CLARITIN-D because the other day I took two in 1 day by mistake, and started shaking and sweating, which I have been doing for the last 3 years off and on, don't know if I have been taking to much of the drug (2 a day) or it is the drug. In the last 3 years I have failed a EKG, My joints hurt, by legs hurt, I can't sleep, don't have any energy, exhibit diabetic symptoms, and my prostate numbers are up and it hurts. I haven't taken CLARITIN-D for 10 days now, no shaking and sweating so far, I am allot tired then I was, seem to sleep better but it has only been 10 days.		M	48	10 years		1/2/2010 Email
4	Seasonal Allergies	Stuff works great for allergies, but recently noticed sexual disfunction.	I'm a healthy 28yo male who has NEVER had any erectile issues in my life. Took Claritin-D sporadically during high school & college, but never noticed any issues (probably because I wasn't getting laid). Recently started taking Claritin-D again because I think I'm allergic to something in my new girlfriend's apartment. I had the same libido and desire, and was able to get it up and it worked fine for a few minutes. Then when it was my "turn" I couldn't reach orgasm and it went limp right in the middle of having sex. She freaked out, I freaked out, made for an uncomfortable situation... If you're sexually active & start noticing any problems, stop taking the Claritin-D!!!	M	28	3 days		12/20/2009
4	year-round allergies	None	A godsend. I can breathe when on this medicine. I get very few sinus infections. I've been on the med for a long time, and will probably be on it for as long as it is made. I finally got the docs to write a prescription for it so I would have to be treated like a criminal when asking for the needed amount to have some for trips.	F	31	10 years		11/16/2009
3	Allergies and Sinus Infection	Dryness in eyes and complete loss of sex drive; couldn't keep an erection up no matter how exciting the situation - very embarrassing	Not sure if it is the Claritin D that's causing it as it seems to be to others using Claritin D, but I am going to get off it and see if my sex drive goes back to normal. Definitely helps with allergy symptoms though.	M	42	5 months		10/31/2009
5	Allergies	Increased energy, increased mental awareness, euphoria, dizziness, extreme loss of appetite, slight loss of physical coordination. I also experienced a weird "rubber legs" type feeling when walking, not quite enough to be debilitating or bothering though, just weird. ONE ISOLATED EXPERIENCE: Tremors, excess sweating, extreme dizziness, delirium, inability to stand, nauseated. This was one unique experience among almost 100 doses, and the variable that proves to lead to this was lack of any food and nearly no water consumed the day of. Make sure you drink up, this almost happened again yet I drank two glasses of water when i started feeling really dizzy and felt better.	Eliminated my nose problems completely and I feel like I can breathe better more than ever. I feel like it gives me another lung. This is a great drug that does great at what it is prescribed for, as long as you are aware of the side effects, and take it early to sleep. And be healthy and stay hydrated!!

1	Nasal Congestion	I took Claritin-D and Levaquin together. It is the first time in my life I got 0 sleep all night. I am stopping both after 1 dose.	I'll stick with regular Claritin.	M	53	1 days		10/20/2009
2	Allergies	While taking: moodiness, intense hunger, sleeplessness After stopping: nosebleeds, mouth ulcers, swollen tongue, sore throat, severe acne breakout.	Claritin really does control my allergies and I didn't really connect all the other symptoms at first. The real horrors, though, are the withdrawal symptoms. It's been about a week now and I am still not normal.	F	36	14 days		9/25/2009
1	common cold	erectile dysfunction. midway through. im 18. enough said.		M	18	3 days		9/25/2009
2	ALLIGERIES	Anxiety	It helped my alligery but wow what an anxiety attack i had.i will stick with the allergy	M	41	1 days		9/24/2009
5	Bad Allergies	Dry mouth mostly	I've been experiencing symptoms of depression...i.e. lack of interest, sleeping more, not wanting sexual activity, fatigue, etc. (no suicidal thoughts thank God). Stopped taking Claritin cold turkey about two weeks ago because I ran out. I have been taking it for years on a daily basis for my allergies. Now I read these comments and it's clear to me that I'm experiencing withdrawel. Time to buy more Claritin.	M	38	5 years		9/23/2009
2	Sneezing, itchy eyes, congestion	Severe drop in libido. I am a very sexual person, and am just about always hot for my girlfriend. Ive been taking this drug for 2 weeks or so and have noticed a drop in my sexual drive. I can keep up with the best of them and lately I cant keep it up at all. This compleatly cures my allergies but the side effcet of my penis not getting or staying errect is not ok. It would be nice if they put this on the box.	Be careful it does cause ED.	M	33	2 weeks		9/21/2009
2	For Allergic Asthma	Oh boy, it cleared up my lungs so i could breathe, but the anxiousness, nervousness made me feel horrible. I had to stay in bed or seated most of the day. If I got up to do any kind of physical activity my heart would pound out of my chest! It is now 8:40am the following day and my heart beat is still up and down....oh, and my asthma is back to :(	Be careful with this Med! Esp. if your older with pre-existing heart conditions!...For Eg. heart palpitations	F	38	1 days		9/17/2009
1	cold	could not sleep!!! not hungry		F	39	1 days		9/16/2009
3	Seasonal Allergies	Basically, i felt like i couldn't think. This is hard to explain, but it would be like pictures that usually flash through your mind as you think were in-existent. A very detatched feeling....almost along the lines of what "depersonalization" is described as.	Ive taken claritin since i was 14, and never really experienced anything too crazy like this....but i noticed this year around the spring time, i started gettin bad allergies and started taking some claritin....at the time i was working at an airport. Anyways, i started to feel as if i was unfocusing with one eye, as weird as that sounds....like my right eye was dominant and seeing more, and id constantly have to reassure myself both eyes were working by closing one and than the other, etc. After stopping the claritin, i felt find a few days later....than my allergies came back and i took it again, this time i felt as if everything i was looking at i was just seeing right thru...like i would look at the computer screen and have to focus on it or it would feel like i was lookin right thru it....after stoppin the claritin, the feeling went away again....now, here i am with fall allergies taking claritin again and for the past days, ive had the same "difficult thinking" feeling...NEVER AGAIN. Also, complete drop in sex drive....still able to get it up but no cravings or even wants	M	24	4 days		9/12/2009
2		severe insomnia		M	57	1 days		9/8/2009
3	2 wks of horrible rash all over	It fixed the rash for the three days I took it, but then the rash would come back again before 24 hours. So altho I only took it once a day, it was sooner than ever 24 hrs. But this a.m. I awoke in wee hours with pounding heart and unbelievable agitation. Rash is driving me insane w/ itching, but I just cannot take any more Claritin. Don't know what is causing rash. Will see Dr. tomorrow -- have ruled out ldry det by switching. Dryer sheets?	I know this is a good drug for some in my family w/ allergies. It just isn;t for me!	F	53	3 days		9/2/2009
1	Severe year round allergies	Mood swings, dizziness, vertigo, heart palpitations, tachycardia, fatigue.		F	31	2 months		8/20/2009
1	allergies	depression	very weepy, irritable, won't take again	F	31	1 days		8/13/2009
4	BAD ALLERGIES TO EVERYTHING!	Well, how can I explain that my sex drive went completely south. I was the biggest contributor to the performance of SEX but not anymore, I think the Claritin company is directly or indirectly the ANTICHRIST because without sex how can we procreate? Or maybe they are just simply trying to protect us from horrible sexual transmitted disease OH DANG IT OK OK JUST DON'T TAKE THIS ROTTEN DRUG IT'S REALLY BAD FOR US ALL!!! After reading the rest of these comments I now understand why my heart beat races everyday and I really don't have an appetite. The good thing is that this drug does work and I feel great in the morning, it's unfortinate that it's so addictive, but we have to stop taking if it's causing more harm to our bodies!		M	28	2 years		8/12/2009
4	cronic cough from post nasal draini	It is 2am and I am still awake. My mouth is dry. It has dried up my drainage. I have had this problem for over 10 years. It seems to help but at what a price?	I will skip taking it tomarrow and try taking it in the morning of the next day. Maybe I can sleep. Nothing else has helped my alergies as much as this seems to but I need to sleep also.	M	71	1 days		8/11/2009
1	Allergies	Loss of libido, fuzziness in my head, panic attack, no appetite, mood swings, hair falling out	After reading the other comments on here, I realized WHY I have had no sex drive for the past month. My husband has been complaining and now I know why! I stopped taking it the other day and I feel like I am going through withdrawals- this stuff should be labeled "crack". No wonder that they make methamphetamine with this stuff. If you are trying to kill your appetite and lose weight and don't mind risking your life to do it, be my guest...as far as for allergies, there has got to be something better!	F	29	24 days		7/27/2009
3	severe sinus headaches, congestion	I always experience erectile dysfunction when I take this medicine. Its terrible because without the medication, I'm fully functional at any time! My wife hates it and is asking me to switch medications.	Claritin-D 24 Hour almost always relieves my sinus headaches. Once or twice per year, I have to take an 800mg ibuprofen with Claritin to relieve the migrain-like headaches that are completely debilitating. My allergies are so severe at times, I cannot function without some type of antihistimine and decongestant. I guess I will try Zyrtec or some other medication.	M	40	1 years		7/14/2009
3	Seasonal allergies	After about 6 months, I developed severe depression, difficulty urinating & sexual dysfunction.	Unfortunately, my doctor (ex-doctor) wouldn't believe that I had these side effects from this medication, saying that he'd never heard of such things before. The depression was severe & downright scary. All the side effects stopped almost immediately once I stopped using the drug.	M	51	6 months		7/12/2009
4	Seasonal Allergies - NasCongestion	Minor dry mouth. Difficulty sleeping at night.	I'm surprised to read about all of the negative side effects from loss of appetite & moodiness to decreased libido! EEK - Sorry to hear about all of that. I should be thankful I have had such a positive experience aside from some sleeplessness (I switched to the 12 hour), but in all it's glory, with our VERY high grass pollen counts along with hot wind this weeek, this stuff ain't cuttin' it. I'm hating it and wish I could double the dose... which is why I'm online searching for anything that says NO! Now I'm thinking I better not push my luck so I don't turn bi-polar, anorexic or bald!	F	35	30 days		7/9/2009
4	I have horrible allergies	Complete loss of appettite! dry mouth, alert, focused and full energy. Now Im wondering about hair loss?	I absolutely love it for aleggies. Aside the dry mouth, I actually love how I feel.Im focused, alert and energetic (not in a jittery speed way either), I lost weight and kept it off too. Negative, after reading other comments Im wondering now if my hair loss is a side effect? No good! I thought I had a vitamin difficiency, maybe its the claritin D?	F	28	3 years		7/2/2009
4	Allergies, bad nasal congestion	I have only been taking Calriton D-12 hour for 3 days, but I have noticed a complete loss of appetite. Usually I am a big eater, but I am never hungry at all now. I have also noticed that I am very very alert. The first day I took it was at work around 10AM, I went from tired and feeling awful from sinus pain, to totally awake, focused, and my sinus troubles were gone. Every day, before Clariton D, I would get off from work and be completely exhausted and need a nap. Now, I have so much energy to where I get off work and want to go do something and stay busy. Its so strange! Yesterday though, I felt like I was on drugs. I seriously wondered if the Splenda I used had crack in it! After reading this site, I now know that it was the Clariton. I am going to continue taking it and see if the drugged feeling reoccurs.		F	22	3 days		6/21/2009
2	eye allergies, normal allergies	Hair loss was like none other. No part of my diet, exercise, or lifestyle changed all that much. I took it for pretty intense eye allergies / minor asthma, and it definitely took care of those symptoms. However, random areas of hair loss became noticeable after a month of claritin. I stopped taking it, and weeks after I am still shedding, waiting for it to grow back.		M	21	1 months		6/21/2009
3	seasonal allergies	it did stop the sneezing, swollen eyes, scratchy throat, and temperature but did make me feel light headed and drowsy. after reading other comments i have noticed that I've been pretty depressed lately and i haven't been sleeping as much. i've also been irritable and I'm usually an even tempered person. i also have noticed a loss in sex drive as well	it did heal my symptoms but i like being happy and up beat so i'm going to stop taking it immediately	F	21	10 days		6/18/2009
1	allegies	anger beyond belief body buzz i hate this med made me crazy		M		8 days		6/11/2009
5	Severe pollen allergry and sinus pa	Definitely can cause insomnia if you don't take it very early in the am; definitely suppresses appetite, can cause dry mouth	It WORKS! It's the only thing that stops my drippy nose. I know they say pseudoephedrine is the big bad evil drug, but those other poser allergy meds just don't work.	F	32	45 days		6/7/2009
1	Allergies	Claritin D actually works on my allergies, but man it has totally killed my sex drive and has made it impossible for me to fall asleep or get an erection. Very embarrassing. I wish they would list this as a side effect. I am going to have to change my allergy medicine. I can't go on like this. Too embarrassing and hard to explain.	If you are a sexually active person: DO NOT TAKE CLARITIN-D. If you don't have sex it works fine.	M	30	7 days		6/4/2009
2	seasonal allergies	Zyrtec was not working for me, so I switched to Claritin. Yeah, it got rid of my congestion and my itchy, watery eyes, but i have been experiencing vaginal dryness-- I can tell you that I was not expecting that. it sucks!!!		F	20	2 days		5/28/2009
1	seasonal allergies	I'm on my honeymoon.....I married a very sexy woman....I can't get it up guys. Can't keep it stiff. Try consumating a relationship when you have erectile dysfunction. 2 very unsatisfied people on this end...Thanks claritin....my wife thinks she doesn't do it for me.....try explaining that one...		M	24	3 weeks		5/27/2009
3	Congested and blocked ears	my congestion was relieved but it really effected my libido. I was unable to get an erection during sex no mater what and then started ejaculating without an erection or orgasm. Really freaked me out.	I found this site and saw guys with similar problems like mine so I flushed the pills down the toilet. Not all that great.	M	29	3 days		5/13/2009 Email
1	runny nose sneezing itchy eyes.	I took it for a few weeks a couple years ago. quit taking it due to mood swings. I recently took it and did't think about the previous side effects...well I almost lost my girlfriend and my job due to the jittery nervious side effects. Also experienced ittitabilty and just was very hard to get along with.	It really should be pulled off the market...yeah it works but I would rather have the runny nose than to be unemployeed and alone.	M		2 weeks		5/12/2009 Email
2	Idioathic Anaphylaxis	Although the claritin D 24 hour stopped severe drops in blood pressure from anaphylactoid symptoms, I ended burning out my adrenals and it caused severe drops in blood pressure from position changes and dehydration. It also seemed to cause a small heart murmur, racing heart rate, thyroid goiter (and therefore difficulty swallowing and hair loss), and shortness of breath when laying on my left side. General malais that improved once off the drug. Muscle fatigue.	Please be careful when taking this drug if you have a thyroid condition, adrenal insufficiency, or heart condition or if you develop these conditions while taking this medication.	F	28	3 years		4/22/2009
3	seasonal allergies	After only 3 days of taking the 24 hr Claritin-D, I started getting an intense, fairly sharp pain at the bottom of my stomach. Then I felt cramps, churning in my stomach and intestines. This lasted for about 12-15 hours after taking the third pill/third day. Early this morning I woke up without stomach pain. Since I was not taking anything else, I am assuming the Claritin-D 24 hr is the culprit.	I started taking the D 24 - recommended by my doctor (first time I ever took it), over the regular Claritin because the pollen count in my area was quite high. (My doctor could see the pressure building in my ears.) Normally I get itchy eyes, runny nose. This season - itchy eyes, pressure in the ears, and my throat felt swollen. Maybe the stomach problems were coincidence......but I don't think I will take the chance again unless I am even more desperate. I am going back to Alavert, regular strength. I had good luck with that before. I rated it a 3 because it does "work" (itchy eyes are gone)......like dropping a sledge hammer on your toe will work to take your mind off another pain. I would NOT recommend the D version to anyone I like or don't know.	M	44	3 days		4/19/2009
3	Seasonal allergies, Pet allergies	I started taking Claritin D to help keep my pet allergies at bay. When I started taking the product I already had a slight cold. After using this medication since March 21 it seems that my cold does not want to leave. My congestion clears up for a little while then it comes back with a vengance and usually at night. It's suppose to work for 24 hours. Obviously, that's not the case. I'm trying to ween myself of the medication but so far, if I stop it really hits me. I also experienced dry throat, sleepless night, and for some reason, it seems to have triggered my asthma which I haven't suffered from since childhood.	Side effects of this medication should be made perfectly clear to the consumer especially regarding long term effects.	F	35	27 days		4/16/2009
5	I have allergies all year long.	I just took a Claratin-D an hour ago and I'm starting to feel light headed.	I have really bad allergies and have used regular claritin years ago. I stopped using it and switched to other products but no luck. I just bought some claritin-d 24 hour for the first time. I have very bad nasal congestion and one nostril is always completely blocked, espeacially at night. I hope this will give me some relief and will report any other side affects if they occur.	M	38	1 days		4/15/2009
4	allergies	light-headed (like i've had 2 glasses of wine), loss of appetite	I'm only 1 day in, but I've already noticed that I'm not hungry at ALL. I had to force myself to eat a banana this morning, and its been 6 hours and still no hunger. I'm usually over-eating (hey at least i'll lose a few pounds). I also feel light-headed. Not enough to interfere with work, but enough to notice it.	F	23	1 days		4/15/2009
3	skin irratation/eczema	The main side effect I have experienced is total loss of sex drive. I am 24 years old and typically had an active sex drive, but since taking claritin 24 hr, that has all but completely diminished.	I am glad to see that I am not the only person experiencing these side effects. I finally put two and two together when I actually sat down and realized that my lack of libido has been occuring the exact duration of time I have been taking claritin.	M	24	2 weeks		4/8/2009
4	decongestion,	watery mouth, constant urination, sleepiness	I keep having to swallow my saliva constantly, or I try eating something salty.	M	19	2 days		3/26/2009
4	Allergies	Significant insomnia and minor muscle aches	I always take Claritin-D 24 hour when I start suffering from my allergies. No other medication seems as effective. The downside is insomnia and muscle aches for 1-2 days after initially taking the drug.	M	22	2 weeks		3/23/2009
4	Allergies-sore throat ..sinus drain	shorter patience, less sex drive-although everything functions fine.	I take the 24 hour dose everyday to avoid nasal drip, itchy eyes and sore throat. I experience sinus drain problems if I go more than 48 hours between doses and can lead to sore throat. It works great for me where zirtec does not. I live in Florida if this makes a difference. I have had bad allergies all my life and claritin has been my savior! I can live with the side effects.	M	44	10 years		3/20/2009
5	I did have allergies...	Loss of appetite, burst of energy, dry mouth	I absolutely love Claritin-D! I used to use regular Claritin, but last year my allergies were especially bad. I decided to try this stuff and I was extremely satisfied! I had just had a baby a few months before I started taking it and I was having trouble losing the baby weight. I started taking Claritan-D and I literally had to force myself to eat! Even pizza didn't appeal to me anymore! I ended up losing quite a bit of weight. I believe I was down to 90lbs for a while. Just a warning: This might only pertain to petite individuals (I only weighed 115 max to begin with,)but after taking this drug for a while it becomes very dificult to eat for days, even after you have quit taking it. I would recommend that this drug be taken every other day or so to avoid this appetite malfunction. Also, due to my starvation, I was always in a bad mood.	F	22	14 months		3/17/2009
3	For Plugged Up Ears	I have been having frequent urination, urge to pee, I pee large amounts at a time, unlike a UTI... After looking at the other comments, I think I might could add that I did notice I was unusually depressed this week (although my hubby was gone an extra long time) but I seemed to be easily upset over many lil things... but mostly I think it may be the medicine that is making me pee so much.	In addition to the peeing alot, I've also lost 8 lbs this week! I am on Weight Watchers, but I've never lost so much at one time... this was concerning.... and I am figuring that afterall- I DID pee ALOT of liquid out! I'm guessing it's this medicine. ON the upside: 2 nights ago, after taking this stuff for @ 1 wk, and before that, I tried the Advil COld & Sinus, I did start feeling intense heat & moisture & noises, as if my ear was draining. Perhaps it is doing it's job? I do hope so, and quick, so I can lead a "normal" for me- life again soon! ;)	F	30	7 days		2/26/2009
3	allergies, snoring	disrupted sleep patterns, hair loss	This is really all about the hair loss... I never made the connection- I lost a *ton* of hair while taking this drug- huge amounts of it wound up in my shower drain, every day. I started to be able to see bits of my scalp (and I'd always had a lot of hair). I thought it was just getting older or some sort of genetic thing. I stopped taking claritin about 2 months ago- and the hair loss seems to have stopped! Now I just hope it starts growing back. I'm posting this for anyone else looking for info on this connection- if you're on Claritin D and suddenly losing your hair- bingo! May not happen to most people, but some of us must be very sensitive.	F	39	1 years		2/24/2009
5	year-round allergies	Does give me a "wake-up" similar to coffee, but not anxiety or jittery	I have taken Claritin and Claritin-D (12 & 24) for 15 years with no problems and great relief of allergy symptoms (itchy eyes & throat, sinus congestion, sneezing). I got allergy shots for 5 years, but still needed claritin in addition to the shots. The effectiveness wanes occasionally and I have tried allegra, zyrtec, and others with no significant relief of symptoms. All meds work differently for all people and the side effects vary widely from person to person. My parents with allergies have good results with zyrtec, but not with claritin.	F	42	15 years		2/6/2009
2	seasonal allergies	TERRIBLE fatigue and weakness; general malaise; loss of appetite; weight loss	I've been taking this drug about 2 weeks. I have been so tired I can hardly function. Today, I am so zoned out, my poor kids have had to take care of themselves. I love food, and I haven't really wanted to eat for the last 7 days. My tiredness has gotten increasingly worse each day. I was really freaking out thinking something was very wrong with me...after reading all these reviews I am convinced it is the medicine. I am not taking it anymore!	F	38	2 weeks		2/4/2009
3	Cedar Fever	Racing heart; Dizziness; Tight head	This week is the first time I've tried Claritin D. It worked so well for my cedar fever (itchy watery eyes, runny nose, sore throat, etc...) that I started taking it every morning. This is probably the 5th or 6th time I've taken it and it may be the last. All of the sudden my heart started racing, I got dizzy and my head got really tight. I think my heart has slowed a bit, but my head still feels very strange. I'm at work and it's making it very difficult to get things done. I am not sure whether the relief from the allergies is worth this feeling. I will likely try the 12 hour instead of the 24 hour next time.	F	29	6 days		1/23/2009
1	Bad Allergies	NO SEX DRIVE!!! Dry Mouth, Stomach Bloating, Jittery, Extremely Alert. This stuff makes you feel like you're high on drugs. After only about 12 hours after taking it I noticed something in the "sex" department wasn't right. I can't wait until this crap is outta my system!!	Any questions feel free to hit me up	M	30	2 days		1/19/2009 Email
1	allergy	Dry mouth, jittery, anxiety. It may have helped a little with my allergy symptom of a stuffy nose but 24 hour means 24 hours of the above mentioned side effects including inability to sleep. Will not use again.		F	56	1 days		1/18/2009
1	Allergy Headaches	Very Rapid Heart Rate of 133 and increased blood pressure. Felt very jittery in my arms and anxiety was raised.	Will never touch it again. My heart is a bit more important than a few headaches. I would never touch this stuff again.	M	37	2 days		1/9/2009
1	Allergies	I took a Claritin-D 24 hour at 11am and it is now 2:45am the next day and I can't sleep. Also, I was getting road rage today. I am usually just a calm driver but this afternoon I was getting mad at everyone on the road. I understand now after reading this site that it was probably the Claritin.	Yeah, I won't be taking this again.	M	38	1 days		1/5/2009
4	allergies	some insomnia. some loss of sexual libido.	It will help clear up allergies!! definitely. Try not to take it at night as it can keep you awake. If you have shortness of breath and wheezing from allergies, this is your med.	M	51	5 days		1/2/2009
3	Severe allergies, all year	Had no appetite, no libido, insomnia, irritability and more fun stuff...	Let me just say that this stuff works exceptionally well for severe allergies. I took it regularly when I had bronchitis and multiple bacterial infections and it will work. However, it has EXTREME side effects. You will never be hungry, lose lots of weight, become more moody, people will think you're hooked on illicit drugs and you will be a person, at any age, with no interest in sex etc. My recommendation is never to take the Claritin d 24 hour, unless you're having a severe allergic reaction. Otherwise, take only the 12 hour Claritin-D when you MUST.	M	24	9 years		12/9/2008
3	Claritin	Claritin or Claritin-D destroys my sex drive. I mean it is literally gone. The medicine works for my allergies, though.		M	33	3 years		12/3/2008
3	Severe Sinus Infection	Horrible insomnia! I would only be able to sleep in 45 minute increments. Never felt rested. Headache. Eye pain.	It definitely worked on allowing me to breathe clearly, but unfortunately, it did not allow me to get any real sleep. Going to have to stop taking it.	M	40	3 days		11/27/2008
4	Allergies to everything!	I take when I wake up and I have not noticed anything that affects my normal day to day activities. I work midnights so maybe it fuels me and I don't know it and by the time I am off I am ready to crash, so sleep is fine. I have noticed weight loss and have not changed my crappy eating habits at all. I only take half of a 24 hour pill. Kind of afraid to take whole one when half works so well.	I like it. I have tried all the other stuff, nasal spray included and I always come back to C-d. I guess I buy into the newer is better ads for a bit then I find I return to what works.	F	34	2 years		11/26/2008
5	Seasonal Allergies	After peeing, I feel like I have to pee right away again but if I try again no urine comes out. Though after taking the drug for 1-2 continuous months this feeling stops. Other than that eveything else is good.	This stuff works really well for me. I take it in half the year when allergies really get to me.	M	23	2 years		11/19/2008
5	Allergies	Clear sinuses, no sneezing, no drippy or stuffy nose, eyes no longer itchy...RELIEF! Also would tend to agree slightly with people who said it feels like they are a little high/loopy/jittery but hey...it's cold medicine...there will be side effects. Also to the woman who posted towards the bottom of the page that she gave this to her 4-year old son--I TRULY hope that it was the child's version of this drug!!!	I almost ripped my face off yesterday due to uncontrollable sneezing, itching, runny nose, watery eyes...not only has Claritin-D 24 hour completely cleared these symptoms, I also get a nice little buzz off it! Everyone else is freaking out but I feel alert, focused, and yes a litttttle like I'm on crack but nothing to have a conniption over. Haha it's a pleasant side effect and WELL worth the relief from allergies. They sell it over the counter for a reason people, it's POWERFUL.	F	23	1 days		11/14/2008
3	Seasonal Allergies	Dry Mouth, constipation, no energy, chest pain, anxiety, irritability, depression, knee pain (possibly related), and recently sleeplessness. The reason I looked this up is because both of my arms and legs have been becoming increasingly more numb over the last week. It's so irritating and sometimes quite painful. I took Claratin during one other season of my life and now looking back I can remember having many of these same side effects.	I know everyone else has said it too, but I'm sooo happy to have found this because it explains alot that has been going on in my mind and body. Now I have to decide if the allergies or symptoms are worse. It does wonders for my allergies.	F	28	3 months		11/13/2008
4	Allergies	Total Erectile dysfunction. After two weeks of one pill daily, I could not become aroused at all, even typical nocturnal erections didn't occur. After 24 hours off Claritan some improvement. After 4 days, I returned to normal. It does help with allergies, but I think I will use another medication	The box should be more descriptive about side effects. I am almost 50 and was truly concerned about this being related to being old. I happened upon this site and found the answer. Thank goodness for the Internet.	M	48	14 days		10/29/2008
2	allergies	head high, feels like i just did coke. legs jittery, attention span affected. anxious, nervous.	I took Claritin-D a few hours ago and found this website when I started Googling things like "Claritin speed" and "Claritin flying". I can't believe they sell this stuff legally... it's like a small dose of cocaine. I've never done meth, but I'm guessing it's something like the way I'm feeling but more intense. On the plus side, it did make my allergies go away. But it seems a little like having your finger amputated because of a paper cut.	M	29	1 days		9/26/2008
3	allergic reaction to sulfa drug	aggravated my innattentive attention-deficit disorder.	I had an allergic reaction to a Sulfa Drug. First took Benadryl which knocked me out. Next day tried Claritin. Reduced rash much better than Benadryl. Made me feel better immediately, appetite returned, felt like doing things again. No longer felt sick or washed out. But next day, started to aggravate my ADD, attention-deficit disorder (normally just the inattentive kind). In fact, it turned it into ADHD (the hyperactive kind). If there's one think I don't need, it's something that makes my thoughts race. I couldn't sleep. My mind kept on racing. Felt loony-toons. I talked endlessly. Does this have a stimulant in it? Because I have the same problem with Excedrin. Would take for short term. But no more than 1 day at a time. 2nd day I felt "high".	F	53	2 days		9/19/2008 Email
1	cold, sore throat	loss of sleep, tiredness, weak, dizziness, loss of appetite, feels like you're on crack.	i hate this drug. its the worst drug. it didnt do anything but make me feel worse. i took it at night thinking i could sleep good, but i was so wrong, i didnt get any sleep. i feel weak, like i cant do anything. the feeling feels like the come down from being high. this drug is bad. DO NOT TAKE IT!	F	23	1 days		9/18/2008
4	Allergies/Chronic Sinus Congestion	anxiety, nervousness	I use it as needed. It works well as a decongestant/anihistamine and side effects are more or less tolerable. I have used for a few years now and still works well.	F	37	3 years		9/12/2008
3	Allergies	Insomnia. Every time I take it I either wake up after only 3-4 hours of sleep or am able to sleep all night but only in 45min increments. Nasal congestion sometimes too.	gets rid of most allergy symptoms, just at a price.	F	19	4 years		9/9/2008
5	Allergies	None - only a sense of feeling very well-rested and slightly energized in the morning which I have always attributed to being able to actually BREATHE!	Before Claritin D, I was often so congested that I would awaken with severe, debilitating sinus headaches that would keep me in bed nearly all day. I would try other decongestants and/or antihistamines, hot showers or baths, ice packs, whatever. The medicine has been an absolute miracle for me, and I have not had ANY adverse side effects. I have taken it nearly as long as it has been available - 9 or 10 years - and have had NONE of the problems some others have listed. I take a 12-hour tablet before bed, sleep very peacefully for 7 to 9 hours, and wake alert with clear sinuses, ready for a very busy day. Although I have tried the 24 hour, I have found that personally I don't need it. I have taken occasional small breaks from 12-hour Claritin D without any withdrawal symptoms (a few days to a week here or there), but when my year-round symptoms unfailingly flare up, it is always Claritin D that keeps my sinuses clear like a charm and helps me to remain the happy, calm, productive pers	F	52	10 years		8/23/2008
1	Allergies to Dust, Mold	I took this medication because I ran out of regular Claritin. Although it is "Non-Drowsy" it made me feel very lethargic and slow. I also experienced depression and felt like crying all the time. Lastly, it made me anxious and nervous.	I would take regular claritin, but definitely not Claritin-D again.	F	17	1 days		8/22/2008
1	fever; stopped up nose	frequent urinating, takes a few minutes to start peeing!, cannot stop worrying, lazy, short fuse with co-workers and others i come in contact with, sweating, cant stay asleep or awake, feels like i'm high or something, no aches or pains.	stay away from people that irritate you ex: Macbook salesman at bestbuy, mcdonalds drive threw, girlfreind/wife etc. dont overdose!!!!!!	M	22	7 days		8/19/2008 Email
3	Allergies	Severe sleeplessness, painful dry mouth, anxiety, loss of appetite, loss of weight (2 lbs. over the course of 4 days) most likely due to loss of appetite, insanity	I took this to help with my postnasal drip and it did somewhat, but the side effects nearly drove me out of my mind. I rapidly lost weight, which really scared me and only increased my anxiety. I had horrible nightmares when I did finally fall asleep, but the worst thing was the dry mouth that became so painful I almost went to the hospital.	F	26	4 days		8/5/2008
3	allergies	My allergies feel practically non-existant, but the medicine makes me feel insane. Really depressed. Cold. I could sleep all day long. I don't want to go anywhere. Be VERY careful when taking this product.	Totally works for my allergies, but dangerous.	F	19	6 days		7/25/2008
1	allergies	Jittery, couldn't concentrate, elevated b/p, anxious, felt HIGH!!!	No wonder they 'hide' this drug behind the counter! Cheapest high I've ever experienced. I felt like I had just 'done a line'! This, and all medications, are CRAP, if you ask me! Trust me, I did my drug experimentation during the 80s but don't ingest ANYTHING...perscription or OTC...anymore. The doc insisted I take this. Well, the doc can take it! Take it and...well, I do want to remain civilized here. Trust me, your doctors aren't giving you medications, they're giving you DRUGS!!! I think anyone addicted to their prescriptions, and who believes the lies their doctor and the drug companies feed them, are not only ignorant but as addicted and no better off than someone using street drugs. Ask Rush Limbaugh!	M	62	1 times		7/24/2008
1	allergies	I have never experienced any side effect as powerful as the sleeplessness caused by Claritin D. I absolutely cannot fall asleep - and each time I take it I have absolutely no allergies, and no sleep. Note - an audiobook is fantastic during the sleeplessness because although you may be tired the drug keeps you aware and alert.		M	28	1 days		6/29/2008
1	Allergies/headache, itchy nose	Nightmares, increased heartrate, insomnia, euphoria.	Initial symptoms were aleviated, but side effects were far worse. I thought I was going crazy until I found this site...so glad I found it!	F	32	5 days		6/24/2008 Email
4	allergies	Erectile Disfunction. No doubt about it, if Clariton D is active "Oh Henry" aint.	Take only the 12 hr and only when you really need to...plan ahead.	M	44	3 years		6/20/2008
1	Alergies	Sleeplessness. I can take sudafed without any issue. However, after taking Claritin-D 24 hour I was unable to sleep. After goign to sleep at 12am dead tired, woke up at 3am, 4am and 5am finally got up and checked for side effects on the box. Did a google search for Claritin-D 24 hour sleeplessness and see that I am not alone in the insomnia department.	Anyone want 9 free Claritin-D 24 hour?	M	26	1 days		6/12/2008
4	seasonal outdoor allergies	I had no side effects. I left this product for the Z brand and came back. love claritan		F	31	3 months		6/11/2008 Email
2	Claritin-D 24 Hour	Craziest 'over the counter' allergy med I've ever taken! I took one around 7am and by 10am I thought I was getting the flu. Over the course of the day I developed severe anxiety and heart palpitations. Absolutely could not fall asleep that night. Overall symptoms were: Dizziness, anxiety, heart palpitations, nervousness, flu-like symptoms.	I thankfully realized that it was the Claritin causing these symptoms and discontinued use after that day. I would, with out a doubt, NOT recommend this product to anyone!	M	26	1 days		6/3/2008
1	Pet Allergies	Note: this is after taking Claritin-D 12-Hour. Over the past 6 months I've started to believe that I have a pseudoephedrine sensitivity and have been avoiding the drug. However, I had to take this medicine today because I woke up to my eyes swelling shut with allergy and it was all I had available. Took the medicine at 11 AM and experienced rather severe drowsiness and irritability during my work day (enough to make me walk out.) Slept from 3 PM to 8 PM. It's now nearly 5 AM and I CANNOT sleep. I would've thought the medicine would be out of my system by now. Skin crawling, teeth numbness, jaw stiffness, trouble focusing, trouble breathing and swallowing, nervousness and restlessness. A definite overall WEIRD feeling. I'm recently coming out of a three month bout with nocturnal panic attacks, anxiety (have always had but had been able to control in the past), paranoia, and insomnia. So, as you can imagine, this is a nightmare! A single pill has sabatoged months of struggle. Though, I'm	Any of those prone to anxiety, depression, panic, insomnia, hypochondria, or paranoia should BE WARNED before taking Claritin-D. The negative effects are much worse than a runny nose. If you experience any of the side-effects I mentioned having after taking Claritin-D, I strongly recommend avoiding ALL medicines containing pseudoephedrine in the future.	F	19	1 days		6/3/2008
3	Congestion, sneezing	Sleeplessness, Dry mouth, anxiety	I took one 12hr tablet at 3:00pm. It caused dry mouth fairly quickly. By 8:00pm I had a feeling of anxiety. Went to bed at 10pm with no problems, but, woke up at 2 and couldnt fall back asleep until completely exhausted around 5:30am. I am trying it again but taking the med before lunch.	M	40	1 days		5/31/2008
5	For my allergies	I didn't experience any side effects. The product is great! I feel really good. Much better than going through all of the previous discomfort. I will continue buying this product.	I would recommend your product to anyone.	F	53	30 days		5/28/2008
1	indoor allergies	immediate feeling of discontent. couldnt sleep at all throughout the night. alternate feelings of cold and hot. mood swings and feelings of depression. when it says "non drowsy" it means it...this stuff makes you crazy. definitly should not be OTC!	if you cant take sudafed...dont take this!!	F	21	3 days		5/27/2008
4	Allergies	Sleeplessnes, dry mouth, energy, loss of appetite	I now split the pill in 1/2 & make sure I take it as soon as I get up in the morning. 1/2 is enough to completely clear my symptoms but avoid most of the unpleasant side effects (except the dry mouth).	F	33	30 days		5/12/2008
1	Allerggies	I am taking Claritin D 12 Hour for the past three days and have not slept in three days - I will never take it again -		M	37	3 days		5/8/2008 Email
2	seasonal allergies	insomnia, shakiness, panic attacks, couldn't breathe, rapid heartrate, tons of energy and felt very focused, dizziness- very hard to drive, lost 10 lbs in only 3 days (and i'm already a size zero-- didn't really have any weight to lose), major loss of appetite, dry mouth- did help with the allergies though.	this was only taking a 12 hour pill once in the morning.	F	26	7 days		5/6/2008
1	Allergies	Anxiety, increased heart rate, restlessness, dry throat, sleeplessness, irritability, foggy disconnected feeling ... depressed and overly emotional ... crying over nothing. I thought there was something seriously wrong with me until I realized the only thing that could be causing it was the Claritin 24-hour tabs ...overall I exercise daily, am happy and healthy, and found this over the counter medicine to be horrible. Never experienced anything like it. My wife took one and it had absolutely no effect on her at all. Very bizarre medicine.		M	38	7 days		5/5/2008
5	Congestion	Sleeplessness	This stuff works great! Most of my life I have dealt with a stuffy nose and almost always breathed through my mouth. When I take this, it makes me alert, clear-headed, and I can actually breathe easily through my nose - a miracle! The only problem I have with it, is that I only get a few hours of sleep during the night, no matter what time I take the pill. Think I'll try the 12-hour when this box is gone.	F	29	8 months		5/3/2008
2	Sinus allergies	Weight Gain -I put on 6 pounds in 3 months,other side effects dry mouth , Bloating, restless. I go to gym regularly and all no where i put so much weight. It works for my allergies but with a big price :(	I am going to stop it, but don't know how to cope up with allergies. all allergy medication seem to have same side effect.	F	27	120 days		4/21/2008
1	seasonal allergies	I went on Claritin-D years ago and gained 15-20 pounds, but I convinced myself that other factors were to blame. I recently went back on it (a week ago) and although I am barely eating and exercising, I'm gaining weight rapidly. It might be water retention, but it still is quite extreme and not that time in my cycle. It also seems to be causing me depression and crying jags, though I cannot say with any certainty that it is caused primarily by Claritin-D. I just threw away the remaining tablets.		F	45	6 days		4/16/2008
3	seasonal allergies	I've never had a bloody nose before and now I've had three small ones since taking Claritin-D 24 hour. My throat feel like I have to swallow all the time. I've had shaky hands and feel anxious.	I'm glad I found this web site, I thought I was sort of crazy.	F	56	2 weeks		4/15/2008
5	allergies	hard time sleeping	works great but take in the morning	M	30	3 days		4/13/2008
4	allergies	insomnia	I will never take this product again due to the insomnia! It is nearly 6am - I have been awake 24 hours - thank God today is Saturday!	M	57	2 days		4/12/2008
4	seasonal allergies	i usually take regular claritin redi-tabs but recently switched to claritin-d about a week ago. it works great for clearing up my symptoms (although i'm still sneezing a bit), but it's not worth the restlessness and anxiety when i try to fall asleep. i usually have very long days and exercise regularly, therefore i have no trouble falling asleep and getting at least 6-7 hours a night. with claritin-d i have the hardest time falling asleep - my mind is racing and i can't get comfortable. when i wake up in the morning i feel irritable and unrested.		M	27	7 days		4/9/2008
2	Seasonal Allergies	Knees were weak and made horrible cracking noise; ended up having knee pain which I have never had before.		F	36	2 weeks		4/8/2008
3	seasonal allergies	the first 2 days no sleep,irritability,dry mouth,no appetite,moodiness,heart palpations,raised blood pressure,runny nose,vivid dreams,nightmares		F	53	2 days		4/5/2008
3	Congestion - Snoring	Mixed bag - - I am a bad snorer. Claritin D 24 hours significantly improved this problem and is the main reason I continued taking it. Great for the marriage! - Erectile dysfunction. Significant depression of ability to have sex. Terrible for marriage! - Changed personality. Positive, bolder, less minor depression. - Significant energy gain. - Great for a hang over. Take one in the morning and wow. - Definitely breathed better.		M	55	8 months		4/4/2008
