i have taken Zyrtec for years during the fall during ragweed season - works great for me without any side effects. My husband can only take it every other day as it makes him feel flu -ish. 18 yr old takes as needed and it works great. 16- yr old has allergy asthma and has taken Zyrtec for years and now with Singulair. She now is experiencing all noted problems of sleeplessness, headache, anxiety, and grumpy. We are quitting the Singulair to monitor improvement and will do the same with Zyrtec if needed. NOTE: Each person most be monitored with every drug for allergies and side effects. If you or your child cannot tolerate a drug, STOP taking it. You are your best daily diagnostician! Your DR. may not agree or understand, but pursue another course. REMEMBER though, that drug may be a lifesaver for millions of others that react favorably! Penicillin is a miracle drug unless you are allergic! Doctors should encourage close monitoring whenever your kids take a new drug - but when they don't - that's our job!
