I started taking Montelukast 6 weeks ago and it has REALLY helped my asthma. I was poorly and frankly quite worried about my worsening asthma when I started it.
However pretty much within days of taking it I noticed I was a bit grumpy but I had PMT so I assumed it was that.
Recently I've gotten so agitated, aggressive and quarrelsome. Between getting into rows on FB (who does this, not me ever before) and making rude hand gestures at drivers who cut me off. That last one scares me as what the heck was I doing? I know its rude and foolhardy.
Has anyone else (adult) noticed this side effect?
