Im on amoxicillin for the antibiotics,and apri is my pill that I take. the doctor told me that they WILL effect it and that it will make it not work as good. I was just wondering if it was ok to take the 2 together. the doctor wasnt my normal doctor and they didnt know exactly what kind of BC I was taking and I didnt ask. (kinda dumb I know) but yeah. thank you!!! =) I never would have thought about how long it stays in your system though. kinda good think to remember when it comes to these sort of things!!! lol! thank you! thank you! and thank you again!! =)
