Hello, ThisisMS seems to be causing posting difficulties again for me, so I have brought your questions here!(1) I know Sarah took Roxithromycin 150mg 2x per day, but Dr. Wheldon recommends Azithromycin 250mg 3x per week. Why Azith over Roxith? And why only three times per week, not daily? I'm curious about this later dose. For full disclosure, I've been taking 250mg daily, but skipping a 1-2 days per week, and anecdotally, I always feel a touch worse when I skip.
