Montelukast
"This medicine changed my life. After 18 months of constant post nasal drip, coughing up sputum, sore throat, and nasal congestion, I think I may have finally found my answer. I have taken almost every medicine suggested to me and seen over 30 doctors. I was finally put on this for Rhinitis and Asthma and I started to notice a big difference by 4 days in. It has now been a week without coughing up sputum (something that I had daily for 18 months), and my congestion and breathing is significantly better. For some reason antihistamines and inhalers don't seem to help me, but Singulair does. I'm so glad that I tried this medication!"
