 3  Stuffy nose, watery eyes, sinusitus Severe depression especially with the generic brands. Several medical doctors told me this was not a side effect related to Claritin but I am certain it is. I have a comprehensive knowledge of psychological conditions and earned a degree in this area. After taking each pill, I feel like I have been crying all day. Furthermore, I feel like I should continue crying the rest of the day. If I didn't have a solid grip on my emotions, I would definitely experience crying spells. However, this medicine is the ONLY medication that remotely controls my allergies so I have to take it. My allergies are so bad that I'd rather deal with the depression :-( F 25 3 years

 3  seasonal and pet allergies I have taken loratadine (generic Claritin) during the springs and falls for 3 or 4 years... this year is the first time I've had any problem. Just recently, I've gone though several periods of extreme irritability and was extremely sensitive to touch and temperature. After eating, I get sharp pains in my abdomen and lots of gas. A general feeling of lethargy is almost constant, but it is sometimes very difficult to fall asleep. I didn't make the connection that these side effects were probably due to the medication until I read this site- I figured it was digestive problems combined with some off-schedule PMS. Claritin suppresses my allergic reactions for the most part, but occasionally it seems like it's doing nothing at all- my throat and eyes will get extremely itchy for short periods even while on the medication. I'm going to try to stop taking it daily and just have some Benadryl on hand if my symptoms start to get bad. F 20 3 years

 3  Allergies. Stuffed nose, itchy eyes I was sitting at work, having my lunch, when I experienced heartburn (I never get hearburn). All of a sudden I experienced what felt like a panic attack (heart racing, out of body feeling, dizzy). Thought I was going to have to call the fire rescue. Went away after a couple of minutes. Very odd as I don't take it everyday, only when my allergies become too bothersome, and I usually have no side effects (been taking it occasionally for a couple of years). F 31 3 years

 3  Allergies Destroys my sex drive. I mean I literally become asexual. Works for my allergies, but this side effect is depressing. M 33 3 years

 2  Sneezing After reading all these other comments, I now realize that the rash on my face that hasn't gone away for a year, as well as the unexplained 10 pound gain of water retention, swelling of the face, and my lack of sex drive may all be related to it. I thought these were all seperate problems affecting me for various unexplained reasons. I stopped taking the Claritin about 4 months ago, but still have rash and low sex drive. (Lost the 10 pound of water in days and face swelling!) Will the rash ever go away? The product always helped my alergies, and after an ear operation, I even found that doubling the perscription kept my ears and sinuses dry and normal. Now years later, after taking it daily, I think these other issues with my health may be related. Both my dermotologist and internal medical doctor can't explain the rash on my cheek, and I am worried it may never go away, and that I may not regain my sex drive, even after I stopped taking it. Is that possible? M 42 3 years

 2  Hives. It works really well for hives. I used to take Benadryl but it made me so stoned I could barely function. I started taking a generic version of Claritin when I moved to WA from Los Angeles, because all the pollen was making it worse. However, I've been super bitchy and mean basically since I got here. I've also been more depressed than I've ever been, and borderline suicidal. I have a history of mild depression and anxiety, so I figured it was moving and other life changes but after reading all these comments I think I prefer being stoned to being awful to people I care about. Try it but pay attention to how you feel emotionally. It works really well for some people, and again, it completely controlled my hives. It just made me a psycho-hose beast. F 25 3 years

 2  For allergies. For two years have been diagnose with severe anxiety. It has never improved, except during certain times of the year. When ? When I was not taking Loratidine. Severe anxiety, déjà vu and vivid nightmares. Trouble breathing, quite short of breath, night sweats, severe distraction, muscle aches in my back and loss of appetite. Made the connection after realizing that every time I took it I got bloated, and soon after felt fatigue. I stopped it for 2 days and the difference was inmense. Am hoping that I can get it out of my system and then get rid of my anxiety meds. M 37 3 years

 1  Seasonal allergy Anxiety, weak arms and legs, irritability, insomnia, stomach pains, waking up several times during the night. Side effects didn't happen all at once. Sometimes had usual side effects of drowsiness and other times I would get a random side effect of feeling irritated or anxious. M 22 3 years

 1  It helped with my vertigo I have taken this off and on for 3 years, as it helps dry up the fluid in my ears which causes my vertigo. I took one last night and ended up spending over 2 hours of agony - uncontrollable shivering, teeth chattering, felt cold, couldn't get enough air -was breathing as fast as I could - heart rate was incredibly fast, nausea, vomiting. I was ready to call 911 as I knew I could never drive a car.. I kept saying this will go away eventually, but it terrified me. After about 2 and a half hours I was finally able to slow the shivering and the breathing slowed. It took me 14 hours to feel semi-normal again. I have thrown out every claritin in the house and will never take it again, nor recommend it. Will be calling my doc about this Monday. Very, very scarey! F 54 3 years

 1  allergies It took a long time to pin down the symptoms to the medication. At first I was taking this daily for allergy symptoms. I would suddenly become very groggy...felt like my mind was in a fog. I also experienced symptoms of depression, moodiness, and anger. I began to have problems with sleep...would wake up very tired and found myself needing almost 10 hours of sleep/night. I battled really bad nightmares which was something I had never had a problem with before. When I started taking the mediations only every 3-4 days I then could pin point the symptoms were directly related to the med. It worked well for allergy symptoms, but I would never recommend this to anyone due to the side effects I have experienced. F 45 3 years

 1  For year round allergies I started out taking 24 hour Claritin D about 3 years ago. Shortly afterwards, I went to 12 hour tablets but only once a day because the 24 hour tablets made me very edgy and just one 12 hour tablet seemed to get the job done. I thought I was doing okay until I recently started taking two tablets a day for additional relief. I have been sleeping very little and now I'm starting to feel paranoid. Lately, I have been very irritable toward my family. After reading the comments posted I'm starting to realize Claritin was affecting my life a lot more then I ever realized - even at the 12 hour/once a day dosage. I'm very thankful for this website. Last night I thought I was going crazy. I'm very thankful that others shared their experiences. It helped me to understand that some of the changes I've been going through the past 3 years has more to do with the medication I'm taking and not just a matter of M 55 3 years

 1  Major allergies I was prescribed 10 mg Claritin daily, which I took for 3.5 years. I gained 50 lbs, yes, fifty pounds in 2 years! Never having had a weight problem, I went to several doctors to find out why this had happened. Most told me I was crazy. Think about it: going from 118 pounds to 170 pounds in 2 years!!!! Who wouldn't freak out? I took myself off Claritin and within five days I had lost 7 pounds. It is two years later and I have lost 20 of those 50 pounds, but now my thyroid function is extremely low, and I have to take drugs for this condition. I blame the Claritin for my thyroid problems because I never had any thyroid abnormalities before I began using the drug loratadine. Please force your physician to get to the bottom of the problem if you have experienced similar abnormal weight gain in a short period of time. I do not think anyone should take medications for which there have been no long term usage studies performed, which is the case with Claritin---the longest time period in its clinical trial was 6 months.

 5  seasonal allergies I have been taking Claritin for several years and have never experienced any side effects. Both my daughters take it and likewise have had no side effects. In fact, I work in a health clinic as an RN and have never spoken to anyone who has had side effects from this medication so I was amazed at all the side effects reported here. It works very well controlling sneezing, itchy eyes, nose and throat. It works quickly (within 30 minutes) to relieve my allergy symptoms and generally lasts the full 24 hours. F 45 4 years

 5  Severe Allergy Symptoms In 4 years of taking Claritin I haven't noticed any certain side effects. I've been looking to see if anyone using claritin regularly for this long has experienced a loss of the sense of smell which began this year. I've also had some dryness issues that began this year only. I've been off of the claritin a week now and neither of these symptoms have gone away and I am more dehydrated. Other than the severe dehydration I haven't noticed anything like withdrawal symptoms either. I'm not sure if my loss of ability to smell is related to the claritin or not. Claritin has been a life saver for me. I had severe itching, watery eyes, sneezing, sometimes hives and claritin would clear all of this up with the possible exception of the very peak of the allergy season. Then some nights I would supplement with benedryl. I never had any side effects that I have noticed until perhaps this year. M 43 4 years

 4  Allergies I never experienced any side effects with Claritin/Loratidine, but I did find that Claritin D made my heart race, which in turn made me very anxious (I hate pseudophedrine). Just plain Claritin has been great for my allergies. Now that I've stopped taking Claritin, I've been having anxiety attacks and insomnia. It only occurred to me today that these anxiety issues could be linked to discontinuance of a drug that sometimes makes other people sleepy (my boyfriend, for instance). F 35 4 years

 4  allergies None that I am aware of. Works OK with mild allergies. Really doesn't help when I have a massive allergic reaction to dust, mold, cats, and pollen. To be fair, nothing works very well with my twice a year extreme reactions. I have to take benedryl, claritin, chlortabs, and a nasal spray to stop the itching in my head. F 47 4 years
