A member asked:
On amoxicillin for strep, i know when on birth control it's important to use a backup method but how long after meds is it no longer necessary?

Give it some time.: Medications take some time to completely wash out of your system after you've taken them for a while. I'd recommend you use barrier protection for one week more after completing your course of Amoxicillin to play it safe.

Newer ideas on this: The current thinking is that except for the antibiotic rifampin, other commonly-used antibiotics do not alter the effectiveness of birth control pills. Of course, this is presuming a person is not sick with vomiting or diarrhea, or some other condition that decreases the absorption of a swallowed pill.
