Is it okay to take estrostep (ethinyl estradiol and norethindrone) fe with minocycline?

Yes but: Always safest to use condoms as well when taking an antibiotic and birth control pill. It will give you some extra piece of mind.

BCP & antibiotic: I am not clear if you are taking the bcp for pregnancy prevention or acne tx. Antibiotics can reduce bcp effectiveness in some women. You might need to use condoms to further decrease chance of pregnancy and need additional/alternative form of bcp while using minocycline. Tell your dr. Everything you take including vitamins and herbs.
