Can Your Medications Interfere with Your Birth Control?


If you are taking birth control, you want to feel certain that you can depend on it. If you are taking a hormonal form of birth control like a pill, the ring, or the patch, you will want to be sure that any medications you are prescribed will not interfere with the birth control. While most medications are safe to take, there are some medications known to affect birth control.

  • The antibiotic ripamfim, used to treat tuberculosis, can interfere with birth control.
  • Medicines for mood disorders and epilepsy can make birth control less effective. Not only that, but birth control can also make these types of medicines less effective at their job. Be sure to discuss other possible options with your doctor.
  • Some medications for HIV can make hormonal birth control less effective, though there are antiviral options that will not interfere with birth control, so be sure to consult your physician.
  • Herbal supplements, because they are not regulated by the FDA, can have ingredients that could potentially mess with your birth control. St. John's Wort, an herbal remedy often used for anxiety and depression, is known to reduce the concentration of hormones in the birth control pill, which could affect its efficacy. Talk to your doctor about any herbal supplements that you are taking.

It is always a good idea to discuss with your doctor any medications you are taking while on birth control, so that if necessary you can switch to something different or use a backup method.
