Was having a conversation with my uncle, who's been a pharmacist for something like 40 years, about what antibiotics could cause or worsen T. I brought up Zpack and he said he's never heard of it in the 1000s of scripts he's filled for it. What's you guys experience with this? I read Dr.Nagler from ATA say you shouldn't give a T sufferer erythromycin or azithromycin. I'm especially curious about this because I took Zpack right before my T started and probably will avoid anything but amoxicillin personally.
