Hello i have a question about clymidia . i took the one doze pill yesterday and i feel sick is this normal ?

Maybe a side effect: The single dose treatment for chlamydia is azithromycin. Nausea, abdominal pain, cramps, and/or diarrhea are common side effects, but usually start in a few hours. If "feel sick" means lower abdominal pain, it's possible the chlamydia has infected your fallopian tubes, i.e. pelvic inflammatory disease (PID). If your symptoms continue for more than another day, definitely contact your doctor.
