My 7 year old twins were both prescribed this drug in Nov last year, come the new year they had both become angry and aggressive and very emotional little boys. In particular one of them, I couldn't so much llok at him without him telling me I was cross with him, he was going to kill every body and I was called in to school on 2 occasions following him attacking a teacher. This was completly out of character, after some interent research (which I know may not be a good thing) I made the decision to stop giving montelukast, and the changes in them are astonishing, and commented on by everybody. In particualar at parents evening their class teacher was running through a 'time line' of probelms and character changes, which match to starting and stopping the drug, but she was oblivious to the medication.
I wonder if anyone has had a similar event? I am still toying eith whether it is the right or wrong thing, but It seemed so unfair to alolow a tablet to do this to my children?
