Singular has been recommended to my 3 1/2 year old son. I didn't feel good about it, so I declined and decided to look up possible side effects. Wow! I will NOT be giving it to him! I have always been cautious on giving him antihistamines because prior bad side effects (which I never heard anyone else complain about). When he was a few months old, he had cold like symptoms (runny nose, congestion, etc.) and was really suffering. I gave him the over-counter Pediacare and he could breathe better but he became something out of a horror film. He screamed constantly for over 48 hours and did NOT sleep a wink! Like a "crack baby" or something. (I assure you I am not exaggerating). I too became sleep deprived and crazed by his constant screaming, it took me some time to realize it was the meds. When I quit giving it to him, he became normal again. I decided I had to deal with the symptoms and not give him meds. A year later, different medicine, I tried again. Same results. When he was 2 1/2 we took a road trip from KY to KS. I thought I would try Benedryl, he had 2 older syblings that it benefited. NOT for him. He became "crazy" and screamed to the top of his lungs for the entire 12 hour drive. I vowed never again (for him or his family). I have had success with Claritin in less than normal dosing. With no side effects. I have been assured, however, that Singular would work better for the symptoms. No thanks. I feel really bad everyone this has effected negatively. I understand the side effects first hand. I too have heard of the "antihistamine blocker" but don't know if it works. I plan on trying a "nettie pot" (natural alternative) and have heard great allergy success stories. You can get them for about $5 at Walmart. Hang in there parents! Do what you have to do for your child. Trust your instinks even over the Peditrician. I love Docs but YOU know your child. :)
