The birth control patch prevents pregnancy by transferring hormones to your body through your skin. This method uses a 28-cycle. You apply a new patch each week for 3 weeks (21 total days). No patch is applied the 4th week and your period should start during this patch-free week.
There are three options for starting your first cycle of the patch:
Wear the patch for 7 days. On day 8 apply a new patch for Week 2 and on Day 15 apply a new patch for Week 3. Do not wear a patch during week 4 and your period should start during this week. Every new patch should be applied on the same day of the week. Patches can be put on your buttock, abdomen, upper outer arm, or upper torso in a place where it won't be rubbed by tight clothing. Never place a patch on your breast(s). Do not leave patch off more than 7 days.
Abstain from intercourse or use an additional method of birth control such as a male condom if you have intercourse during the first 7 days of this cycle.
Note: refer to the package insert for problems or questions about use of the patch, such as a patch falling off or forgetting to apply a patch at the proper time.
