 5  Allergic all seasons Allegra D 24 hour - Dry mouth, nose and eyes. I've experienced these with any allergy med I've tried. Wow, I can't believe how many people have suffered negative affects. True, every body is different. I take this every day of the year for many years! First thing in the am, on empty stomach. On the occasion that I have missed a dose, I really notice! I WISH I experienced the energy and the loss of appetite that people talk about. Does not affect my sleeping. F 49 9 years

 5  ongoing allergies I take Allegra D once a day at 7 am or so. I don't take it at night because it interfers with my sleep. It pretty much eliminates my allergy symptoms. It does leave me impotent, but that is not a problem for me as my wife and I have a sexless marriage. M 51 3 months

 3  sinus congestion and allergies Took it around 6:30 before leaving for work. Experienced Terrible insomnia even though I took it early in the morning. Couldn't stay asleep more than three or four hours. Awful stomach pain and loss of appetite. Some itching. Weakness and dizziness when standing to quickly Unfortunately the other otc didn't work as well as this product. I'm in a lose-lose situation F 3 days

 1  For congestion and sinus headache This medication is awful. I had dizziness, weakness, loss of appetite, slurred speech, racing heart rate, itching, confusion, headache, vomiting. This should not be on the market. I thought I was going to die, I have never experienced anything like this from another medication. F 1 days
1X D

 3  allergies, sinus inflammation This drug really does clear up my nose and helps with sinus inflammation. HOWEVER, the side efects make me take this ONLY if absolutely necessary. BAD Side effects: Insomnia (Little to NO sleep, even when taking this in the morning), Heart racing/jumping out of skin. Dehydration cause you don't feel like consuming anything. 'GOOD' or tolerable Side effects: WIDE awake, like I had several cups of coffee, Focused/Sharp, No appetite so helps with weight loss I don't need to lose much weight, so it concerns when I don't eat at all and don't feel like eating all day. F 28 1 weeks
1X D

 5  Allergies, Sinus problems Drastic increase of sexual desire. Does a good job keeping my sinuses clear, but my sexual desire is just crazy. Its not as bad as when I accidentally got GNC Mega Men: Performance & Vitality instead of Sport, but its really frustrating. When I get home from work I am chasing and begging the wife...but I can breathe... M 33 2 months
1X D

 5  Seasonal Allergies Gave me more energy, cleared my nose, has not helped too much with my cough, but I don't have an appetite which is fine. I am 70 pounds overweight and can stand to lose some of the weight. That really sucks for the people that can't take this, but what works for others don't work for some other people. I am so glad my doctor switched me from Claritin which did nothing for me to the Allegra D. I am only going to take it for 10 days then they want to put me on the regular Allegra, I hope the regular Allegra works the same. F 44 2 days

 1  skin allergy, itchiness Huge headache to the point of nausea, numbness in muscles in face, nose felt swollen inside so I couldnt breathe, shortness of breath, heart palpitations, foggy head couldnt concentrate, pain in head behind eyes got so bad I thought I was having a stroke When I first took this medication it worked almost immediately, and my skin felt much less sore and irritated. However, after a couple of days I began to get a headache that would not go away regardless of the amount of pain killers I took. The pain behind my eyes and nose was frightening, my face felt numb on one side, I had tingling in my fingers and arm, problems sleeping even though i was exhausted. I couldn't concentrate, didn't want to talk to anyone and had trouble doing simple things such as checking my change in a shop. I have stopped taking the medication since yesterday, and already the headache has subsided and I can now breathe easier. I am very sad that this drug had such frightening side effects but would never, ever take it again. Just to add, I am not on any other medication whatsoever and am in excellent health apart from the skin allergy. F 61 14 days

 5  seasonal allergies restlessness,insomnia,bloating,acid reflux,jittery,decreased appetite F 40 4 years

 5  Severe allergies Side effects: Loss of appetite, insomnia, lots of energy. I do wish I could sleep a bit more but even without sleep I do not wake up tired. I am ready to hop out of bed and start my day by 3am. I force myself to lay in bed a few more hours, usually playing on my phone. I have had severe allergies my whole life. I have tried every medication on the market to no avail. My symptoms have almost vanished now! I am thrilled with how this works! I have also lost 24 pounds in 2 3/4 months, but I needed to so that was a blessing. Not sure how to stop the weight loss as food does not appeal to me in the slightest. I do often feel a bloated feeling very high up in my stomach. As if a tennis ball sized object was lodged right between and just below my breasts. I think that is why I feel like I can't eat. Most days its all I can do to eat one small meal. Somehow, I have no side effects from not sleeping or eating! It makes no since but I'm full of energy, happy, no headache, not light headed, not dizzy, nothing... I happen to not drink alcohol or soda and after reading all of the reviews I believe those two beverages along with juice leave many with very bad side effects. F 38 3 months
 4  Severe Allergies Severe appetite loss, but it immediately cleared up my itchy watery nose and eyes. i I just have to remind myself to eat. F 26 7 days

 3  severe seasonal allergies It works great for allergies but side affects are awful I experienced chest pain,headaches,severe back pain,dizziness,insomnia I felt like I was during. But I changed my allergy medicine to chloramphirminee and phenylephrine I feel one hundred percent better . F 42 6 months
 1  ear fluid allergies Shaking. Feel like something crawling in the head. 24 4 days

 3  Seasonal Allergies It works well for my allergies, but I cannot handle the side effects anymore. I take it in the morning and still experience insomia at night. I haven't had a good night sleep in 2 weeks. My heart races and I cannot wear my contacts because I get so dizzy. I have been moody lately, not sure if it's from the meds or from school (lol). I need to switch to something else because I love sleep and I'm not getting any. I just realized that the insomia and allegra D are related. F 22 2 weeks

 1  Extreme allergies Think about suicide and killing constantly. Can not talk to people. Hate everything around me. Can NOT CONCENTRATE on anything other than bad thoughts. Caused schizophrenic symptoms, voices and ocd. Anxiety through the roof. Makers of this drug are destroying humans Worst thing you could ever take. Today was my last dose. I have been on decongestants since 5 years old. I have been off decongestants for a period of 3 years in which I actually worked, felt good all the time, and did wonderful things for myself and other people and animals too. ON allegra-d I am a basket case that hates everyone around me and it has ruined relationships. DO NOT TAKE ALLEGRA D. Company should be sued. M 35

 4  Allergies Insomnia I take this medication at night before I go to sleep (10 PM). I am able to fall asleep, however, each night taken I've woken up at 3:30 AM and cannot fall back asleep. I wake up with energy (not grogginess). Other allergy medications I have tried have made me feel drowsy the whole day. Even though this medication wakes me up, I will continue to use it because I would rather have "energy" then feel drowsy. F 27 30 days

 3  fall allergies jitters, anxiety, strange tiredness I suffer from seasonal allergies. This year they have been worse so after trying other meds, I tried allegra. My allergy problem was gone. I mean GONE! The first day I felt weird, but chalked it up to being tired or something. The second day was even worse. Super jittery, anxious and nervous. Not like myself at all. I am so bummed that the medicine that works so great makes me feel so weird. I saw that some continued to take it and the symptoms got better, but I'm just not sure I can try that... *Please note that no other factors changed while I was taking the meds. I ate the same as normal, slept the same as normal. F 30 2 days

 1  Allergies grass, dust, plugged up Mind was out of control, anxiety, depression, do not take this drug. I have learned the hard way I have lost my fiance partly b/c of this drug. It works but there are herbal remedies with NO side effects I have found. I have been taking allegra-d on and off all my life but more heavily in the last 3 years. Pretty much sometimes twice a day just so I could breath I have been off this drug for 3 weeks now and I have a whole new outlook on life. My mind is not spinning out of control and I am able to think straight and normally now. I can even read a sentence in a book without getting all jittery or pre-occupied with something else. Basically I am normal, calm, and feel better about myself. I have lost the best thing that happened to me, this drug took over control of my mind and brain and made me a person I am not M 32 3 years

 1  allergies to dust mites & ragweed Sadly it took a decade to find out why I was not sleeping, I take the 12 hr at 5 am and cant sleep until 22 hours after taken. Also Recently noticed trouble urinating, I never put the two together, I have had insomia for a decade and never made the connection that it was the Allegra-D that was keeping me up. It does work for allergies.I also had bladder trouble with allegra, complication ith intercistitis (sores in bladder). I tried the Allegra without the D and that didn't work to relieve any symptoms.

 1  Sinus problems It cleared me up immediately and although I was sick, I plowed through an entire day at work in 100 degree weather. But when it was time to sleep -- forget it. I stayed up all night. It's the following afternoon and I tried to nap -- no such luck. Anyone know how long it takes for 1 dose to disappear? F 63 1 days

 1  Seasonal allergies Upset stomach, severe stomach pains After taking allegra d for a week became seriously ill, I have diverticulosis, I had severe abdominal cramping, had to go on heavy antibiotics, only to realize that allegra d does not digest properly and after several days saw a full undigested allegra d in my stool. This could have been life threatening, DO NOT TAKE THIS MEDICATION IF U HAVE DIVERTICULOSIS F 53 7 days

 5  RunnyNose,Sneezing,ItchyThroat Taking 24 Allegra D. Most side effects (sleeplessness, jitters,etc.)go away after a few days on medicine. Still will experience dry/cotton mouth, but I find drinking more water helps. I feel the best I've felt in years. I have more energy. Zyrtec made me feel drugged and tired all day. Claritin didn't work as well, but few side effects. I used to take this as prescription medicine years ago. My insurance these days wouldn't cover it since there were over the counter medications available. I'm so happy that it is now available over the counter, I just wish insurance would cover since it's more expensive this way. F 39 30 days

 3  eye lid swelling w/ allergies Days 1 and 2 Severe reactions: headache, nausea, jittery nerves, anxiety, insomnia, dizziness, slight sore throat, loss of taste and smell, disorientation, intense eye pressure. I'm on day 3 now and most of the side effects have worn off or at least lessened. I think you just need time for your body to get used to a new medicine. It felt like I was on a major coffee overload. And of course with all those side effects it does lead to moodiness and anger fits. You just lose it easier with the nausea, jittery nerves, lose of sleep. Now I just have insomnia, mild headache, mild disorientation, probably can't taste or smell as well as normally but it's probably a good thing because I'm allergic to perfumes as well as grass and pollen. I've had allergies for years but I started taking this medicine because of eye lid swelling that is getting out of hand. After trying the 12 hr doasge for 2 weeks with some improvement, my doctor gave me the 24 hr allegra and flonase to try for 10 days to see any improvement. Honesty I have seen no improvement yet so I can't say if this medicine is going to work..but at least I can tolerate the side effects for the next 7 days. M 37 3 days

 4  allergies Cotton mouth, restlessness, lack of appetite. I use Allegra-D for my severe allergies. It works great, except for the cotton mouth. It does boost my mood (as opposed to zyrtec, which makes me depressed). I find myself forgetting to eat (which I never miss a meal) and my body synthesises it in 10 hours not 12. I don't take it at night - can't sleep. F 45 4 weeks
60 1X D
 5  post nasal drip I love allegra-D! Don't know why so many are posting negatively. Yes, the pseudoephedrine will give you a slight "lift", but I happen to appreciate the boost of energy. Medication very effective in controlling my PND. F 48 10 days

 1  Allergies, Cold - without infection anxiety, nervousness, irritability, slight chest pains, shoulder and upper back pain, faster heart beat/pulse, slight increase in blood pressure, brain fog, eye pressure, dizziness, trembling, slow ejaculation, semen consistency change from thick to runny and quantity less, slight impotence, slight urination change, different urine smell, lack of concentration, and jittery. This is the twice a day pill, 12 hours each pill. After taking the first pill I felt strange, but past it off as being part of the cold, after taking the second pill 12 hours later, I was fine until about 4 hours after I took it, and then the symptoms just started rolling in. I have had a similar experience before, and now I am certain it is this medication. M 35 2 times

 3  Allergies/Congestion Severe lower back pains, low grade fever, vomiting I would advise anyone to ask there doctor to see if there is another medicine with less side effects, it clears my allergies up but like alot of people have commented it has awful side affects. Mine is the 12 hour. M 14 3 days

 5  Seasonal allergies Little constipation from drying out but probably from not drinking enough water, dry eyes wearing contacts. No other noticeable problems. Allegra d 12-hr works best for me. Other allergy meds really dry me out too much to the point of a nose bleed Take it with breakfast every morning and no allergies through the day. My doctor also gives it for sinus and ear infections. Helps with sinus draining. Excellent on those yard days with pollen. M 33 3 years

 1  Seasonal Allergies I have been taking Allegra D for over 10 years & have never had a problem & it was the only allergy pill that worked for me. I only take it in the Summer & Fall when my allergies are at their worse. I started taking it a few days ago & I am having trouble sleeping, bad headaches, vision blurry & I can not wear my contacts - I took this med on an empty stomach, 8 hrs later I ate and started vomiting and I noticed the Allegra had come up & did not dissolve (after 8 hrs). I did not realize it was the Allegra that made me sick, so the next day I took another one on an empty stomach - 3 hrs later I ate a light snack & have been severely vomiting all day, almost flu like symptons, I can not hold anything down (not even water or ice) and again the pill came up and did not dissolve. Severely vomiting and this medication is not dissolving in my stomach. Flu like symptons, headaches, blurry vision. F 37 10 years
1X D
 4  Allergy to dust & pollen I have no side effects whatsoever from using this drug. I would recommend to anyone reporting any side effects to isolate the conditions that may be contributing to your ailments, and work carefully to pinpoint any other factors that may be keying in. Too often, I think we are too ready to judge based on an array of factors that may have nothing to do with the drug. If we are to contribute vital knowledge to potential customers searching for allergy solutions, sharing the proper information is vital, while avoiding misinformation based on insufficient, inconclusive observations.

 2  seasonal allergies /sinus infection restless, shaky, jittery, heart racing, cold chills, sleeplessness I took in late afternoon (5pm)after my initial doctor's appt. At about 2am my heart started racing, I was shaking and I got the chills. I thought maybe it was low blood sugar (which I have never had but my mother does) so I ate something. Nothing helped...symptoms continued all night and was unable to sleep. Had a total of 3 hours sleep and was still completely restless. I am sure I can find something better to deal with my sinuses.
