I am currently on clindamycin for an ear/sinus infection and I was wondering if it would have an effect on my birth control? From what I have read it is supposed to be "safe"...but I deffff do not want another baby right now so I am scared to have sex. Has anyone else had experiences with implanon while using antibiotics?

(And for those smarties who would say to just use a condom, I loathe them, I would rather abstain from activities. I'm allergic to latex and even the non latex ones are rather irritating to me)

How Effective Is Implanon?

Effectiveness is an important and common concern when choosing a birth control method. Implanon is very effective. Less than 1 out of 100 women a year will become pregnant using Implanon. It lasts up to three years.
Certain medicines and supplements may make Implanon less effective. These include

  • the antibiotic rifampin

I have never had any issues with it. my PCM told me i could take anything and it won't do anything hinky with the implanon since there is a constant flow of the hormones and your system builds it up the antibiotic won;t do anything like it does with the pill because you don't have a back stash of the hormones in your body.

When in doubt, ask the pharmacist! I didn't know if Bactrim or Pyridine affected implanon until the pharmacist asked me if i was on anything for birth control or was pregnant. turns out i was safe anyways.
