sinusitis
"I have my 5th sinus infection of the year (2017,) which caused my ear drum to rupture. My doc prescribed me a 500 mg dose, twice a day. Antibiotics in general upset my stomach and should be taken with food, so I made sure to take with a large meal. The one time I didn't was in a rush to get on the road for a trip, and I was nauseous the entire ride, but tums helped A LOT. The infection has cleared up quickly and my ear is draining a lot less fluid out. This has been able to do what four other antibiotics haven't. Take with a full meal, and you will be feeling much better soon!"
