Question/Comment:

I took Singulair for 2 years for allergies. I became severly depressed. I took myself off of it. The doctor said he'd never heard of that side effect. He tried to prescribe it to me again and I refused.

Answer/Reply:

I got the same reaction also. I told my doctor and he said he had not heard of that also. It was in the news!

Question/Comment:

I just started taking singular for unidentified allergies. I've been on it one week and feel so tired all the time plus have a very dry throat. Will these symptons go away with time or get worse?

Answer/Reply from iGuard:

A very small number of our iGuard members, less than 1%, reported drowsiness and dry mouth while on Singular. Although side effect response can be variable between patients, almost all patients felt that the good things about Singulair outweighed that bad things.
