asthma
"Started Singulair approx 1 wk ago. I will say it's an asthma miracle, but the side effects are unreal. I had extreme irritability (out of character for me) severe fatigue when normally active, mood changes, depression, anxiety. I wish doctors would really explain this to new users thanks to all of you who reviewd this medicine and gave me insite on what was going on, that's the reason for my post too. "
