Why do i feel sick after taking ciprofloxacillin as post abortal care?

Nausea is a fairly common side effect with ciprofloxacin and other similar antibiotics (the fluoroquinolones). Taking it with food can help.

You symptoms may be due to the antibiotic you are taking, the abortion you had with possible late complications or may be unrelated to any of the above. Your best reference remains your current prescriber who you should call and report current symptoms so that a proper plan will be in place.
