Birth control backup


about the "morning-after" pill

The morning-after pill prevents pregnancy when taken properly within 5 days of unprotected sex or birth control failure (for example, the condom breaks or you forget to take your birth control pills).

If you are already pregnant, these pills cannot end the pregnancy.

The sooner you take the pills, the more effective they are in preventing pregnancy.

Many women choose to buy the pills before they need them so that they can take the pills immediately when needed.

Learn about types of backup contraception, and how to use them to prevent pregnancy.

Kaiser Permanente members should call their doctor or advice line (24 hour) for information on how to get backup birth control.
