Hormonal contraceptives, including the vaginal ring, are less effective if taken with certain seizure medications. A few medications are affected by estrogen therapies, but this is of less concern when using the vaginal ring for birth control since the dose is very low. Women should talk to their healthcare provider or pharmacist about their specific situation.

Antibiotics can cause hormonal birth control methods to fail. This includes penicillins, tetracyclines, and rifamycins.

Anticonvulsants can cause hormonal birth control methods to fail. This includes carbamazepine, felbamate, hydantoins, oxcarbazepine, rufinamide, and topiramate.

Other medications that can cause hormonal birth control methods to fail include:
  • aprepitant
  • barbiturates
  • bosentan
  • fluconazole
  • glitazones
  • griseofulvin
  • mifepristone
  • modafinil
  • non-nucleoside reverse transcriptase inhibitors
  • protease inhibitors
If you are taking a beta blocker, a corticosteroid, a tricyclic antidepressant, or theophylline, a form of birth control containing a progestin and estrogen may not be a good option for you.

If you are taking cyclosporine, a form of birth control containing a progestin and estrogen can lead to side effects and should be avoided.

If you use birth control containing a progestin and estrogen, you should avoid St. John's wort.
