Chlamydia Infection
"I was prescribed this with another antibiotic. The other was 1 pill on day one followed by 7 days of doxycycline (I&#039;m allergic to erythromycin so I guess this is why I was prescribed this).  Worked like a charm at clearing the infection.  My only woe is that I had been sick with the flu at the time and the pill gave me serious nausea the first few days. I also experienced throat irritation and some gastrointestinal things but nothing major."
