Montelukast
asthma, maintenance
"Hello , I'm an 19 y/o and I've been on this medication for almost 2 months now. Since I've taken it I have extreme nightmares and weird sleeping patterns, all this time I've thought that it was helping me but in reality it has broken my life into piece. I'm can't sleep on a normal pattern and having lack off sleep which has caused me to become irritable and not have a clear train of thought. If yourself or anyone you know is taking this medication PLEASE monitor their behavior and sleep pattern."
