I’m sorry to respond late. I have not had treatment for penicillium because the Mayo doc felt it was unlikely to be causing my CT findings or my clinical symptoms. Once the culture was negative for Mac or other treatable organisms, she changed my asthma inhaler from Stiolto to Advair and my “little cough” was gone in 48 hrs. I’d had a cough for ages and this was a great relief. 😀. She’d mentioned the Stiolto could be making it worse. My “horrid cough” had already improved before the Mayo trip with nasal sprays. It is wonderful not to cough so much. I also use Albuterol neb daily followed by Aerobika and huffing, but am not sure that does much.
