asthma
"I started taking montelukast at the beginning of the winter because I would wheeze at night and had a hard time breathing.  I have allergies and it just got much worse at night and affected my breathing.  I tried Advair and though it helped, I would cough during the day with phlegm and I didn't like taking steroids. I heard of Singulair and asked my allergist to write me a prescription.  Well, I have now been taking it for at least 4 or so months and it works great.  I am back to my normal self, breathing fine and plus, it helps with my allergies A LOT! This medicine is a life saver for me and I love it! I take it at night and no more wheezing."
