Reslizumab
"I started taking this drug in January of 2017.  The first thing I noticed was that within two hours of the infusion, my sinus's felt completely clear. Within three months I got my sense of smell back which had been gone for 9 years.  I'm getting ready to have my fourth infusion next week and am finally starting to feel better with my lungs.  It's not a big improvement yet, but I'm starting to get encouraged.  Even if my lungs don't see much better results, I believe the relief it gives with my sinus's is worth taking the drug.  I will write back again in three more months to see how it is then."
