How long does it take for Augmentin to start working? I was prescribed Augmentin 875 mg twice daily for 14 days. I'm on day 6 of the antibiotic, and it does not seem to help me. They say I have a sinus infection, so I wonder if anyone has taken this antibiotic, and if so how long did it take the symptoms started getting better?
2-3 days you should notice an improvement .... after six days ... hmm ... you should call doc
I took the antibiotic. He ate with my stomach. Sinus infections haha take a long time to get better. This will be a while, but if you get so clogged you can not breathe, you can try smelling the salt water. It made me feel much better.
