Im actually using the birth control patch, but last monday i started some antibiotics and yesterday had sex with my boyfriend,If I started my treatment (antibiotic) on monday and have had sex yesterday ( forgot to take my medicine) will this affect the effectiviness of my patch when I only took it one day?
I had a discussion with my doctor last night about antibiotics and the birth control pill (I'm on both). He said that it was just a theory made up back in the 80s and was never completely proven or studied that antibiotics really did affect birth control effectiveness. Some antibiotics actually enhance birth control pills. He's a smart guy and I completely trust him and what he says...I don't think you have anything to worry about.
(couple paragraphs down is some info)
"There are no scientific studies to show that antibiotics interfere with birth control pills. If you are concerned, however, use a back-up method."
