Azithromycin
"This is my 3rd day out of 5 days on Zpak. The first 2 doses were hard with the stomach pain. But if you eat a pretty good meal like 20 min before you take it then it helps a lot. The stomach pain is only there when the pill dissolves. So eating with it helps it dissolve a lot easier. My coughing really hasn't gone down much. The urgent care I went to gave me a inhaler too so that has been helping with my coughing and chest cold pain. But I can only take every 4 hours. But I do feel better enough to work now."
