http://www.medications.com/effect/view/30303 My 4yr old son has been on allegra for 2 yrs now and it seems that it wasn't doing much anymore. so our doctor prescribed Singulair. He gave us a two week trial to see if helped. Well!!! Our once happy go lucky 4yr old is now very emotional and gets upset v Thu, 08 May 2008 11:51:51 -0400 http://www.medications.com/effect/view/30303?item=8085 Im happy for you that you realized this so early on! So many of us have had our children on it for years without realizing!

They work great for my kids. Singulair gave my boys terrible side effects for years. Don't go down that road with your child! Thank goodness you found out now. http://www.medications.com/effect/view/30303?item=8113
