I used to take Trelegy (b4 being diagnosis MAC) for Bronchiectasis. I had no side effects and found effective. However, since MAC, I was concerned about using a steroid due to some studies linking the use to additional risk of MAC. I asked doc to change and he put me on Stilito RESPIMAT. Currently been using for over a year with no effects. ALSO, the drug company has a program that allows me to fill the script for FREE. Don’t know how long that will last- but grateful!
Hope this helps! Dee
