I am a female, age 22, with straight sexual orientation. I was tested positive for chlamydia, and was prescribe 4 250mg tablets of azithromycin. I took the pills shortly after breakfast. A few hours later I felt stomach pain and threw up. At the same time I felt nausea and wanted to vomit. Those symptoms calmed down after an hour or so, then I had diarrhea. It s been a few hours and my stomach still feels funny and I have lots of gas, as well as loose stool. Is it normal to feel this?
