How Effective Is the Birth Control Pill?
How Effective Is the Birth Control Pill, birth control pills are considered effective, but not foolproof. They’re about 99% effective when you take them correctly. But that’s if you take them perfectly, meaning at the same time each and every day. If you don’t, your odds of becoming pregnant go up to 9%.
After taking mifepristone, your doctor should direct you to wait 24 to 48 hours before taking another medication (misoprostol) by mouth as a single dose. The medications may not work as well if you take misoprostol sooner than 24 hours after taking mifepristone or later than 48 hours after taking mifepristone.

Read and sign the Patient Agreement form provided by your doctor. Tell your doctor if you do not understand how to use this medication or cannot follow the instructions. Mifepristone is available only from your doctor. It is not available from store pharmacies.
