 1  seasonal allergies I felt extreme lethargy shortly after starting on this drug and have just now found the connection. I also am sweating an abnormally large amount. I sleep for an average of 10.5 hours a night since i started and previously it was more like 7. I also experienced a loss of appetite. I gave up two of my hobbies and stopped going to church within a week of starting this drug for no real reason. I felt like nothing mattered anymore and everything seemed like i was in a dream. I have become very inactive since i started this drug and am planning to stop taking immediately. M 17 2 weeks

 1  nasal allergies Serious, debilitating depression which came on after the 3rd day on Claritin, and disappeared about 2 days after I stopped taking it. I've never been depressed before but on Claritin,I could barely get out of bed. Deep, grinding muscle aches in the back and neck. I felt as if I was coming down with a bad, bad flu. There was no warning about the depression or muscle pain on the box. I thought I was losing my mind until I found this website. It was quite frightening. F 46 5 days

 2  cat allergies Im pregnany and my doctor told me to take it while on a trip. I was having very bad bladder spasms, tingling sensation, and frequent urination. It was very very uncomfortable, and I dont get any sleep from it. It worked great on my allergies. no other side effects. Expensive allergy pill for all the side effects people were having, and they need to put warning about using with heart problems more avalible. F 22 2 days

 1  Seasonal Allergies Severe abdominal cramping. Loss of appetite. I began to take the OTC version shortly after my Allegra prescription ran out. Since I was using it while camping I thought it was food poisoning or possibly some bad water. At the time I asked my doctor about side effects and he didn’t mention severe cramping as one. I didn’t realize it was the drug until after 2 other times using it. I’m now happily back on Allegra with the only side effect for me being increased alertness. M 29 2 days

 1  Seasonal Allergies After a couple of days on the 24 hour version, I started getting migraines, and I never had them before. Tylenol & Ibuprofen would barely take the edge off. By the third day and third Migraine I realized that this could be caused by the claritin. As soon as I went off the med, the Migraine went away. I switched back to good old Benadryl, yeah it makes you tired at first, but after a few days you body adapts to it. M 39 4 days

 2  seasonal and cat allergies I've been on Claritin (the 24-hour pill) for about five days and it seems to help with some allergy symptoms, but I don't like the side effects. Fifteen minutes after taking it I get an anxious feeling (bordering on panic). I seem to breathe OK, so I imagine my blood pressure is spiking up. I am super bloated and constipated. I also have sharp stomach pains after eating. Last night, I had a weird weak feeling like I was coming down with something bad. That feeling sorta comes and goes mixed with a nervous edginess. My husband said I seemed suddenly mad at him for no reason the other night and looking back, he was right. I was very cranky and on edge. I seem to sleep OK on the stuff so far, although I am worried about developing some of the other side effects I've read about on this site. In past years, I've been on Claritin for short periods (mostly for cat allergy). It did nothing for my itchy eyes or throat, but it relieved some sneezing and was basically non-drowsy. I do remember feeling depressed on it, but I figured I was just bummed out by the allergies. I decided to try Claritin again this week because I have severe spring allergies and the medication is available without a prescription. I've now decided I don't like the side effects of anxiety, flu-like fatigue, and digestive problems. I think Benadryl works better on the allergy symptoms, although it makes me sleepy. I am going to try taking it at night and maybe try Sudafed and allergy eye drops during the day. It's going to be tough, but the Claritin just makes me feel too weird and I can't afford to develop insomnia because of my busy life. F 40 5 days

 4  Indoor mold/mildew allergies Took Claritin (24-hr); developed ringing in the ears, unexpected (and totally unwanted) weight gain, constantly FREEZING, went from needing 7.5-8hrs of sleep/night to at least 10hrs, and some days I would be very mellow and unmotivated, other days totally wired and jittery. Claritin really helped my mold/mildew allergy symptoms (dark circles under eyes, puffy cheeks, nasty headaches). But, the side effect showed up so strongly after only 7 days of taking Claritin every day, that I've stopped taking it. My MD has now switched me to Allegra. F 40 7 days

 3  runny nose ,sinus congestion jittery,nervousness,heart racing I did not take the recommended dosage (I buy the childrens medication which is liquid form) and maybe this drug is not for me.The RPH recommended it after I told her about my symptoms,watery eyes,nasal congestion.I told her that I never hardly take any kind of medication and no regular medications.This made my heart start racing and I was nervous for about ten minutes.I thought I was going to have to go to the doctor or ER but when I read further on the box it says it has a lot of sodium in it.I have lower than normal blood pressure so this may have been the reason.Its not the drugs fault I should have read the box more clearly but usually this reaction is not a problem when taking medications.I'll just use it for my children who have no problems in that area.

 1  post-nasal drip Insomnia, difficulty breathing, palpitations, chest tightness, extreme fatigue, dazed feeling, joint pain, anger and irritability. It did not cure my postnasal condition, although it has helped with allergies to various pollens. The similarity of my symptoms to those of other users is most comforting - I had been afraid of other possible conditions related to age. I have discontinued this drug and do not think that it should be taken regularly. M 75 10 years

 1  Year round allergies This is a terrible medicine. My nine year old has been taking this for over a year and his behavior at times has been out of control. We did not make the connection to Claritin until recently when my pediatrican suggested taking him off the medication to see if it made a difference in the behavior. The change was radical. Doctors should warn parents about these emotional/behavioral side effects before prescribing this medication to children. M 9 1 years

 4  Nasal congestion due to cold Dryness in the mouth but most importantly having difficulty urinating. Claritin D 24 hour pill works well as decongestion. It is the problem urinating that alarmed me. Claritin is supposed to constrict the blood vessel and shrink it in the nostril area. But apparently it restricted other vessels in the body. M 56 2 days

 1  allegies feeling of impending doom, paranoia, depression, crying for no reason, yelling at family, zombie-like symptoms and terrible dreams. I used to take it years ago and don't remember having such crazy psychological side effects. I have only been on it for five days and today was the worst. I ran out of my family's christmas party crying and drove away. I felt like I was going crazy. When I came home, I got online and started researching the side-effects. I'm glad I came to this site. Now I am sure that it is the Claritin that is causing me to go nuts. Took the last one last night and will not take another one EVER!!! THIS MEDICINE SHOULD BE TAKEN OFF THE MARKET!! F 29 5 days
