I have never taken Arikayce, but I get hoarse from time to time from my daily inhalers. My pulmonologist recommended using cough drops containing a large amount of pectin to coat my throat to reduce the problem, and it works. I have even used them before 7% saline when I had a sore throat. Halls' Throat Ease and old-fashioned Cherry Ludens (without menthol) are my favorites.
