Will Cleocin T gel (a topical antibiotic gel for acne) counteract birth control? I know oral antibiotics do but I am not sure about topical. My doctor said it shouldnt, because it has such a small amount of antibotic, but I am asking around because she did not sound completly confident. If there are any doctors out there, please help! I am wondering if anyone has had a pregnancy come about because of a topical antiboitic counteracting their birth control or know of anyone who has had a side affect from it. Please let me know. Thank you!!
