Comments from related studies:

  • From this study (5 years ago):

  • I was started on spironolactone for acne, already having been on advair for about a month. Within about 2 weeks on the spironolactone, I noticed muscle twitching. Thinking this was a side effect of the spironolactone, I stopped it, but the twitching has continued. Now I am wondering if it's a side effect of advair?
