@terrim thank you for your reply. I ordered Strepfen from New Zealand. Not made or sold in USA. Also my side effects go beyond sore throat. My upper airways are irritated & inflamed. I’ve been on daily Arikayce for two weeks. Doctors know so little about this drug since it was only marketed in October. I’m relying on info provided by Heather and others who were part of the trial. At this point they are way more informative than any doctor Ive encountered. They simply haven’t had any patients on Arikace before.
