NuvaRing and Antibiotics

NuvaRing® (etonogestrel/ethinyl estradiol vaginal ring) is a flexible vaginal ring used as a method of birth control. It is known to interact with certain medications. For example, there is a potential drug interaction between NuvaRing and antibiotics.
Rifamycin antibiotics can make NuvaRing less effective. This increases your risk of unintended pregnancy. It is important that you talk with your healthcare provider prior to taking these medications together, as you may need to use an alternate form of birth control (at least during the antibiotic treatment period). Some of the common types of rifamycin antibiotics include rifabutin (Mycobutin®), rifampin (Rifadin®), and rifapentine (Priftin®).
