Taken for less than 1 month

For Allergic Rhinitis "Took one 24-hour Claritin on Sunday. Within hours, my itchy eyes and runny/stuffy nose had cleared. Took a second Claritin on Monday. Poor sleep that night. Tuesday morning, getting out of bed, I experienced a terrible backache and the beginnings of a headache that Tylenol didn't touch. Backache lasted all day. Stopped Claritin before my third dose. Today is Wednesday, and I'm feeling zombie-like, fatigued, with lingering back pain. Much as I had hoped this might be my miracle pill, it's not. I'm a 70+ year-old lady in good health who will not be taking this again."

For Allergic Rhinitis "This is the 2nd time in a month that I have suffered from dizziness and fatigue after taking Claritin. My blood pressure has dropped to 96/58, which is low even for me. I have always had lower than normal blood pressure. I last took Claritin on Thursday morning, and this is Monday, and I can finally stand up without feeling dizzy."

Taken for 10 years or more

For Allergic Rhinitis "I have been on Claritin throughout my youth. It has never failed me and was great. I am 69 years old and very fit, and Claritin just started giving me side effects like waking up with sudden anxiety, being very thirsty, and also fatigued. I tested myself again after a while, and I think it is true. I’m not on any other medication except 8 mg of Candasartan blood pressure meds, which I have been taking for over 10 years. I’m a golfer and work out in the gym. It’s sad to be no longer able to tolerate certain antihistamines."
