How safe is azithromycin 250mg a day for 12 weeks for barbisia (Lyme co-infection) with Mepron. I'm reading scary stuff about both.

What kind of side effects should I expect. My doc says is easier then the 5 months of doxy an 6 weeks of ceftin I already finished.

Treating a case of Lyme that was undiagnosed for well over 5 years. I'm 80% improved but just can't seem to get it completely.
