That very interesting, I’ve been on singulair for about five months and haven’t had any sleep issues or nightmares. I would say if you’re really co corned about it maybe talk to your physician about it to see if they can help; it could also be dose related as well, but I would talk to your physician I hope this helps

Interesting….I’ve been on Singulair since I was a toddler (over 20 years) and I’ve always been a bad sleeper. I wonder if that has anything to do with it

I’ve been on it for a while, I currently have bad dreams, but my singular backdates that. I know it can happen though

I have been taking singular for years but I take it in the morning. Recently it was connected with severe anxiety though, so that’s something to look at

I had weird dreams taking it, too. It’s a side effect among other things. Do you feel it’s really helping your condition?

I've been on it off and on for three years and I only have nightmares when I DON'T take it. It did recently get a black box warning for newly discovered long-term neuropsychiatric effects, so that may be your issue
