If my girlfriend is on antibiotics and takes the plan b pill will it affect the plan b?

Should be fine!: There is ONLY one antibiotic that affects BC. It's for tuberculosis - Rifadin (rifampin). Otherwise ther's no impact in either direction. Best!

I was on seasonique for 2 weeks and had sex and freaked and got Plan B just in case. The next day I had to start antibiotics. Is there a chance I could have gotten pregnant since antibiotics interact?

Most antibiotics do not interfere with birth control pills. Rifampin (a medication for tuberculosis) is the only antibiotic that decreases pill effectiveness.

I have the Nexplanon implant and have been taking antibiotics for this past week and had a condom break this morning. Should I take plan b? Can I?

I have the Nexplanon implant and have been taking antibiotics for this past week and had a condom break this morning. Should I take plan b? Can I?

You're protected: Nexplanon is one of the best methods of birth control on the market and will not be affected by antibiotics. In fact, only antibiotics that are given to treat tuberculosis will affect the efficacy of any birth control. I do not think that you need to take plan B. however if you are worried about STDs, I would get tested in a week. Plan B is not harmful in any case. Take care! ...Read more
