My 8 year old son has taken singulair for 3 years. I have read the side effects & my son has about 6 of them. His moods have changed drastically, he wakes every night, & he has had night terrors in which he has hallucinations, these dont happen every night. I am meeting with his Dr to discuss this. His asthma usually only acts up if he gets a cold. I am just concerned is we stop the singulair after so long, is there anything to use in its place?View Thread
