 1  For allergy If you have ever had joint pain issues, this stiff will exacerbate it to the point where you may scream with pain as I did with one pill. My left knee blew up to the size of a grapefruit, unable to leave my bed. This is a horrible drug and this side effect should be listed on the box. Never again. Where is the FDA when we need them?

 1  Seasonal Allergies Insomnia, and a very odd sensation in my head . An overwhelming feeling of uneasiness.in my body and head. Two days later I had some wheezing, and pressure on my heart very odd I attributed it to Clartin Clartin did stop my allergy symptoms, but the side effects are too much anything that has a mile long of side effects is not for me! I stopped after one pill. I going to see my naturopathic doctor and go with a more natural option that works with the body without all the side effect, F 3 1 days

 1  Allergies Mood swings, pain in mouth, loss of taste, anxiety, depression While Clariton did seem to help my allergy issue, the side effects make this medication a big no-no for me. I only took one pill and the next day I thought I was losing my mind! I was irritable, snapping at my husband for no reason. I had horrible anxiety and even depression, which I've never had. I was so anxious, exhausted, foggy... It was horrible. My tongue and mouth hurt. I completely lost my taste the NEXT DAY. It's been three days and I still don't have it back. It's crazy one tablet did all this damage. I hope to feel normal soon! I've been researching side effects like crazy and found out in here that these things were happening to other people as well!

 1  Allergies Claritin has given me the worst experience of my life . I had really bad allergies and thought maybe Claritin would help but after a few hours of taking it I had a panic attack and I didn't sleep the whole entire night because of it . I had very bad heart palpitations , nausea , everything bad you could possibly think of . My body went numb , and I became so tired . It's been a day already and I'm still having anxiety / panic attacks . I'm up at 2:27 AM right now because I can't sleep and I believe it's because of the Claritin still in my system . F 17 1 days

 1  Seasonal Allergies Anxiety, panic attacks, mood swings, depression. Only took this medication once, and a few hours later I started experiencing heart palpitations, extreme anxiety, and depersonalization. Lasted for a few hours, and I almost had my girlfriend take me to the emergency room not realizing what the culprit was immediately. Anxiety and depression continued into the next day, though more mild. Horrible experience. M 25 1 days

 1  Seasonal allergies/decongestant This is horrible!!! I took 1 pill it was the Claritin decongestant 24 hour (I had to show my ID behind the pharmacy desk to get them and now I know why) at 10am on Friday after my doc requested it and it now Sunday 10am and I'm still feeling the weird feeling... not as bad as yesterday but it's lingering. Read below: It works great but I suppose coming down off this stuff is worse than the actual allergies. If you have anxiety DO NOT TAKE THIS... you'll thank me later. You'll have this weird fuzzy feeling like you awake or alive but disconnected from a reality... yesterday was worse so I've been drinking more than usual water to get this stuff out of my system. I guess it varies from person to person but I will never take this again in my life. When I got home last night from work and first thing I did was throw that crap away. F 39 1 days

 1  Seasonal Allergies, Post nasal drip Gave 1 dose to my 9 year old son (two 5 mg chewable tabs) and my son had a horrible reaction! This medicine literally made him extremely lethargic to the point he would fall asleep immediately upon sitting down and cry when he stood up because he “just wanted to lie down”. After about 10 hours, he threw up twice and he completely lost his appetite for the day. I had to force him to drink fluids through his limited waking hours to stay hydrated. Never ever ever again. This is our first time trying this allergy medicine (we usually use nasal spray) & we honestly started to take him to the doctor until I found this post and realized it's more common than not for reactions like his to affect kids.

 1  Excess Fluid In Ears Took 1 10mg dose about 5pm after my Dr. suggested it at my appointment that day. About a half hour later, had a pretty bad headache. Had to take 400mg of Motrin. Started to feel drowsy and dizzy later in the night. Went to sleep at my normal time about 2am. SLEPT UNTIL 2 THE NEXT DAY!!!!! Woke up feeling VERY hungover, dizzy, nauseous, drowsy and had HORRIBLE brain fog. Had to take an anti-nausea pill. Went back to sleep until 4:30pm. It is now 7:30 the next day and Im still nauseous, my head feels weird, I still have a slight headache and Im anxious. I hope I feel better tomorrow because I dont feel well AT ALL!!!!! NEVER AGAIN!!!!! I took the regular Claritin(Loratadine). NOT the Claritin-D(Loratadine+Pseudoephendrine). F 40 1 days

 1  Cough, runny nose I am so thankful I came across this website, I just gave my daughter Claritin 4 hrs ago, we were literally ready to take her to the hospital because she'll wake up crying hysterically out of nowhere, like if something is hurting or like if she's scared. She does not let me comfort, her she pushes me away and starts kicking when I try touching her. She only lets her dad hold her, I feel horrible. She's now asleep in her dads arms and I put relaxation music on. I hope this medicine wears off soon. I will NEVER give my baby this crap again. F 2 1 days
