my son was prescribed Singulair melts to put in food for allergies. on day two he has developed a cough that will not stop, a fever and was up before the sun this morning also a bad dream last night. after giving him Tylenol for the fever and Elysium for the cough it hit me that he just finished antibiotics so i checked the web for side effects. i was never told by our family doctor about ANY side effects. i am outraged and he will not be taking this toxic drug ever again. i know my experience is small compared to most of the other stories on this web page but these are our children, our pride and joy why do we want to give them toxic drugs for a runny nose or sneezing and in return we get sleepless, cranky, devil children with night terrors? i think something should be done to stop this drug from being given to any child. what kind of world do we live in? i am appalled at the doctors for letting this happen.
