Azithromycin
sinusitis
"After years of suffering a one nostril clog. I was recently prescribed a 5 day 250MG dosage of Zithromax. 

I had zero side effects and it although it didn't totally clear my sinus infection it cleared it enough for me to know it was absolutely effective and on the right path.

I can now get lengthy periods of use out of my other nostril and that's better than I've had in 10 years."
