Patient :Last night, I engaged in unprotected sex. I am currently on Quasense birth control pill that I take at the exact same time daily. I am also on Doxycycline Hyclate 100mg twice a day. I know that Doxycyline can decrease the effectiveness of birth control pills. Should I also take Plan B to ensure I don't have an unexpected pregnancy?
