Montelukast
"I rate Singulair with a ten because it has done everything I could have hoped for. I am 15 now and started taking it when I was 10 or 11. I am able to live my daily life without worrying about asthma, and I use albuterol 15 minutes before exercise through an inhaler, but without Singulair, I'm sure it would be much worse. I have had absolutely no side effects whatsoever, and I am severely allergic to peanuts, nuts, shellfish, and have had allergic reactions to other medicines in the past. This is wonderful!"
