asthma, maintenance
"I have used this drug for over 15 years. I have asthma triggered by inhalants and the original version has totally controlled my symptoms. I used the generic when it came out because of cost. I started having mild asthma symptoms within a few days. When my local Target switched to another generic I developed hypersensitivity pneumonitis which was diagnosed after over $20,000 in lab work and a bronchoscopy. Back on original singulair..and no problem again. It really controls my asthma and allergic reactions."
