Will cefprofozil affect my nuvaring effectiveness??? I am on the antibiotic and my husband and I did not use another BC method. I am wondering if I should consider Plan. B


Only one antibiotic is known to interact with hormonal birth control methods. That antibiotic is as rifampin, which is used to treat tuberculosis. Unless someone is taking that medication with a Nuvaring, Plan B would likely not be needed. I hope you find this helpful. Let me know if I can answer anything else.
