A member asked:

I had unprotected sex on day 7 of taking tri-sprintec. i took another pill right after. do i need to take more to use in place of a plan b pill?

A doctor has provided 1 answer

Missing data: If you are new to the pill, many docs suggest you use backup BC until your system is accustomed to that pill or 1 month. Some drug companies suggest they are effective within a week, but I tend to be cautious when the issue is so important. If you have been on that pill for months there is no need for additional measures.
