Nuvaring Birth Control

Patient : I've been on the nuvaring since Tuesday. I've been in antibiotics , but I took my last one on either Wednesday or Thursday. They're antibiotics that makes the birth control less effective. How long should I wait until I have sex again?
Doctor :   Hello, Thanks for contacting Nuva Ring is a hormonal contraceptive to be used intravaginally from day 1 of cycles till 21 days and then should be removed to allow for withdrawal bleed to occur. But the effectiveness is indeed reduced if used with antibiotics. If you have taken your antibiotic course till wednesday , then i would suggest to avoid intercourse for a week . If not, then you may use a back up method like barrier contraception for a week before Nuva Ring can re-establish its contraceptive protection completely. I hope i have answered your query in detail, wishing you good health , regards
