Azithromycin
"Had a severe sinus infection that was getting worse over a week and the Doc prescribed me a 5 day, 6 pill Z-pack of 250mg Azithromycin and 10mg Prednisone; 40mg for two days ,30mg for two days ,20mg for two days,10mg for two days and last 5mg for 3 days.

So far this cocktail of drugs has made a vast improvement in only a  few days!

No known side affects at this time, had loose stool, very little appetite and very bad time sleeping before started taking both drugs.

If i had to pick one that's most prominent I would say loose stool.

If you tend to be gassy, where a diaper just in case."
