My 3 years old was on it for 16 days and after the samples were gone i stoped giving her. My husband just got prescription filled up yesterday but i did not give her yesterday thanks god for that. Her allergy dr. told me to give her that everyday and Zertec when needed. These Drs are so crazy i am telling you. I do not trust them for a bit. I have a sister who is a pharmasist and she told me singulair is a very safe medicine but after reading all this i am not going to give her that again. anybody knows about zertec for 3/5 yrs old?
