For Allergic Rhinitis: Recently I have been having VERY bad allergies and went to the doctor. She said that I should try Allegra (not Allegra-D) and that it is available over the counter. I went to the store but could not find any adult 12 hour Allegra. This disappointed me because I knew the 24 hour pills usually don't work. I went ahead and bought the smallest package of pills I could get (5) of the 180mg dosage. I took one and it cleared up my symptoms and made me feel better but that night I woke up after about 4 hours of sleep and could not get back to sleep. I didn't take one the next day as I wanted to get a good nights rest. Yesterday I took another and the same thing happened again. I just want to SLEEP! |

For Allergic Rhinitis: I took Claritin on two occasions to alleviate stuffy head colds and runny nose. I took 2 pills, one each on successive days about a month apart, and a day after taking them experienced both times a bloody nose. I am an older adult and haven't had a bloody nose since I was a child. For Allergic Rhinitis: It was effective for my allergies, however it caused many side effects that are listed nowhere! Depression, anxiety, confusion and sleepiness that was so pronounced I had to pull over while driving. This was the Nondrowsy formula. There are 11 other people who had similar reactions in the support in drugs.com group, under the drug name. I'll deal with my allergies rather than end up in the psych ward. |

For Allergic Rhinitis: I have taken Allegra the past few years during ragweed season which I am allergic to. I take it at night so do not have drowsiness during the day. I find it effective but have one major problem which is a side effect that has caused me to stop taking it - joint pain and weakness especially in my ankles. It became unbearable. As soon as I stopped taking it , it went away. I noticed the correlation last year but thought it was a coincidence. Now I know it's not. Pharmacists and Dr's please pay attention this very real and perhaps more common than thought side effect.
