I took Arikayce daily for 8 months. I had hoarseness in varying degrees. At one point it got so bad I stopped for about a week and then restarted slowly, gradually increasing the time over about a month. At one point, as the hoarseness started to return, I backed off the time and then slowly increased, eventually getting back to the full 15 minute dose. I also pre-treated by taking honey, as recommeded by my Dr. This seemed to help.

I also developed a cough during the treatment. The good news is when I completed the treatment the cough quickly disappeared.

As many people say, everyone is different and reacts different and sometimes you have to make judgements based on how you feel while continuing to take guidance from your Dr.
