 3  Spring Allergies lightheaded, extreme anxiety/panic attacks (something I've never experienced before), mild/moderate depression (something I rarely have), shortness of breath (think anxiety related) I took the generic form for about 2 months but didn't make the connection until today while researching if it was possible that my sudden onset of anxiety could be caused by this medication. I ran across this site and about 95% of what everyone else has experienced, I have also experienced to some degree. I now will only take this if my allergies are more than miserable. I did have relief from my allergies. F 34 2 months

 2  For my 4 yr old son My son became very uncontrollable with many outburst and tantrums daily. He would have violent anger attacks on me and I was beginning to feel like a horrible parent that didn't know what to do for my child. We had been giving him claritin for 2 months and happen to forget to give it to him a couple nites in a row and we seen a drastic change in behavior. He was back to himself, loving and fun. Although it worked great for his allergies I will not give it to him again. M 4 2 months

 2  seasonal allergies poor judgement, uncharacteristic bad behavior in school,lack of focus and self-control. Had an exceptionally bad bout with zyrtec when age 6. Figured out it was due to the zyrtec and discontinued use and switched to Claritin. Had no issues for a long while. Recently switched from the liquid to the tablets now that he is old enough to take them. Experiencing the same type of behavior issues with the claritin tablets and we had with the zyrtec. Is it possible that he reacts differently to the tablets than the liquid? We are taking him off of it altogether and see if his behavior & focus (mood swings also) changes. M 8 2 months

 1  Allergies Something like a yeast infection but not quite, all the itching and sores and some discharage. This drug made me really thirsty, sore muscles, my teeth hurt really bad, nauseated, relentless thirst, diarhea and fatigue. For all the horrible things it did to my body, it never helped my allergies at all. When I first started taking these I didn't realize it was the drug causeing all of these problems. I quit taking them for about a week, everything cleared up, it didn't dawn on me unitl I started taking it again and all this misery returened that it was the drug. The stuff did nothing for me except wreak havoc on my body F 40 2 months

 1  allergies After taking claritin I had a loss of libido. I did a lot of research and found that this is an uncommon side effect. They should warn people about this side effect. I had to spend hours of reseach to find out that it was a side effect of claritin. M 34 2 months

 1  Seasonal Allergies At first I had no side effects from Claritin. I liked the fact that it worked, but I didn't notice any side effects. ( I do not take medications much and consider myself very healthy...take vitamins and eat well.) At some point I started getting dizzy and very confused, but did not know what was causing it until finding this website after two months of taking Claritin 24 hour every day. Also, my hair was falling out...not a problem before taking Claritin. After about two months of continual use the confusion was so bad that I had to second guess every move I made. I was feeling psychotic with continual anxiety right before I stopped taking it. My eyesight was also beginning to be affected and reading was difficult. After finding this site, I immediately stopped taking Claritin. The next day after stopping the drug I noticed that my dizziness was a lot less. The confusion was gradually less. But on day three with no Claritin my symptoms actually got worse. On day four off the d The longer this drug is in your system, the more lethal it gets. The FDA needs to get Claritin off the market. I hope a class action suit is made!!...My life was screwed up for weeks from taking Claritin! F 47 2 months

 1  sinusitis Severe joint pain, muscle aches, insomnia, shallow breathing, agitation, depression, gastric upset, gas. I am generally very fit, healthy except for sinuses. On no other medications. Taking generic 24 hour loratadine (have never taken loratadine-D) once daily. It helped some for a while, not dramatically better though, nose still runs quite a lot. Last few weeks steadily worsening joint pain. First 1 knee, then the other, then the right shoulder. Ache all over. Hurt to walk, or even to breathe. Shoulder hurt too bad to lay on back. Insomnia - normally have slept much better. Can't draw a deep breath, chest constricted and tight. Agitation, negative thoughts, depression, feeling of hopelessness. Increasing constant gas and gut spasms, pain. 2 nights ago laying awake, suddenly remembered I'd been through this before on loratadine. Quit and it all went away. Worse this time. Quit 2 days ago, getting better already. Not worth taking this stuff, throw it away! M 53 2 months

 1  Allergies Anxiety, hypothesia in face,arms, legs,tinnitus, depression, confusion, amnesia type effects, fatigue, headache. Literally thought I was going to die, had ct scan of head and then saw neurologist all for what they thought were neurological symptoms, they decided it was anxiety, neurologist thought Claritin may have been cause or contributed to symptoms, never had anxiety before but this has taken a long time to go away, at time never contributed it to the Claritin as seems to happen so subtly. Looking back over the years I have taken this off and on not for the same length of time and it seems even when taken for a few days it coincided with small bouts of depression. This last time was the worst by far, this is criminal having medications like this available for general sale. M 40 2 months

 1  Allergies Chest pain and tightness, shortness of breath, mild dizziness, pain in shoulders and back and under arm pits, nausea, anxiety/panic attacks, random crying I took the Kirkland/Costco Claritan equivalent in conjunction with Flonase for approx 2 months and it helped with my allergies for sure. After one month I noticed a little wheezing and had a chest xray done at my annual physical that was normal After bout 1 1/2 months the side effects really kicked in and I had chest tightness, shortness of breath, unknow origin crying spells and anxiety. It scared the hell out of me and I ended up going to a cardiologist because I thought I was having a heart attack. All the tests were normal. I went to 2 cardiologists and neither of them paid much attention to me putting down using Claritin in my medicine history. On my own I decided to discontinue the medications and my symptoms for the most part have subsided within 4 days. I still feel slightly anxious today on day four after stopping the meds and a little dizzy, however I feel I will be back to baseline with a few days to a week. This website helped me realize I wasn't dying and it was a serious bad reaction to an allegedly safe drug. If you take Claritin, pay close attention to the side effects and if you feel them coming on slightly, stop taking it immediately. My wife takes the medication for approx 6 months with no issues.

 1  seasonal allergies dry mouth, impotence, problems urinating I have heard it takes a while to get into your system and I started to notice my dry mouth within a couple of weeks and as time went on it got worse. Then the urination problems started and then the erectile disorders. Some people on here put on the same stuff so i'm relieved something isn't really wrong with me. I guess impotence is a rare side effect but it can happen and that was the last straw for me. M 17 2 months

 1  seasonal allergies Mental fogginess, bloated abdomen, heartburn, "air hunger" (couldn't "catch my breath"),and crankiness Took the generic form. My sneezing attacks stopped, my sinuses cleared and all was well for about one month. During the second month, the symptoms of fogginess and irritability began. Then came the abdominal symptoms which made it uncomfortable to eat or even drink my beloved water! The air hunger was the last straw! Two to three days after stopping it, all symptoms resolving.
