Do You Need to Use a Back Up Method When Switiching Birth Control?

by Alexandra Haller

Overview

With the variety of birth control methods available, it could take time to find one that works for you. Knowing what to consider when changing from one method to another can make the process smooth and safe.
Identification

Use a back-up method of birth control if switching from one hormone-based type of contraceptive to another. These methods prevent ovulation by releasing the hormone progestin or the combination of estrogen and progestin hormones into the bloodstream.

Types

Examples of hormonal birth control are all birth control pills, the birth control patch (Ortho Evra) and the ring (NuvaRing), which work on monthly cycles. The birth control implant (Implanon) lasts for three years and the birth control shot (Depo-Provera) lasts for three months.
Process

If switching from birth control pills, the patch or the ring, finish a complete month's worth of the supply before starting with a new method. If switching methods from the birth control shot or the implant, start the new method on the first Sunday after the time frame of the previous method has expired.
Time Frame

Use a back-up method of birth control every time you have sex for the first full seven days of the new contraception. After a week, no back-up method is necessary.
Options

Back-up methods include condoms, diaphragms, the sponge and the cervical cap.
