My Dr. gave me Singulair to take every night because it is the only thing that keeps my allergies in check. I love it and it works great....but it makes me itch like crazy. I stop the singulair, I stop itching, but then I can't breath. I have tried all the OTC's and nothing works like singulair so I try to use it only when I have to. Well I have to now so last night while itching myself to death, I read that Allegra can stop the itching caused by the allergic reaction to singulair so I took one this morning and it seems to help.View Thread
