"I can't use Zyrtec or Claritin because they make my ADHD symptoms worse and counteract my Ritalin medication. This is the only antihistamine that works for me and does not make me drowsy (4-hour version). However, the 12-hour one has made me drowsy."

"I have severe allergies and believe that Chlor-Trimeton has saved my life several times. I have had 10-12 life-threatening anaphylactic attacks over the last 20 years. My attacks usually build slowly, starting with hives, then vomiting and diarrhea, then swelling of my tongue, throat, and inner ears. I have found through trial and error that if I can take a 12-hour Chlor-Trimeton in the first 2-4 minutes after the reaction starts, I can stop the reaction altogether, or at least get to the hospital without having to use my EpiPen. I LOVE this medicine for hay fever symptoms as well. Unfortunately, it is getting harder and harder to find the 12-hour tablets."

"I tried this after trying all others before I got a shot for allergies. I was fine sleeping on it, then took it again the next morning, and within an hour and 15 minutes, I had severe hot flashes, got shaky, wired, and tired/loopy, then nauseated. I just had a second hot flash, and the nausea is hanging on too. I will never take it again!"

"I have been taking this for allergic sneezing, itchy eyes, itchy tongue, and back of mouth, allergic post-nasal drip. Very effective. My grandmother told me about it forty-five or fifty years ago. Don't take it if you have high blood pressure. This is an oldie but a goodie. I prefer the short-acting yellow pills rather than the twelve-hour pills."
