Azithromycin
tonsillitis/pharyngitis
"I'm on my 3rd day of this medication for strep throat and take it on a full stomach every day. I haven't had any stomach pain or diarrhea which I usually get with antibiotics, and no weird metallic taste in my mouth either. 
Only downside is it takes a bit longer to work than most antibiotics, so my throat was killing me until halfway through the day after taking the third pill. 
Aside from that, no side effects and I'm feeling much better now! My tonsil is still a little swollen but most of the pus is gone and no more pain."
