asthma
"My 13 year old son is an athlete who loves running and playing basketball. He excels in both sports as one of the state's top junior high athletes and could not perform at his best without Singulair. Before Singulair, and during the fall allergy season, he would suffer asthma flares while training outside on the cross-country courses and he would have difficulty playing an entire basketball game without using his albuterol inhaler once and getting a breathing treatment after cross-country and basketball practices. We noticed after a week of Singulair what a new person he was, he hasn't used his inhaler for almost a year and doesn't use Advair anymore."
