Using the Birth Control Patch PDF

What is the Birth Control Patch?

The birth control patch contains 2 hormones (estrogen and progestin) that are absorbed through the skin (transdermal). The patch is worn for one week at a time and at least 3 patches must be worn in a row. It prevents pregnancy by stopping the release of an egg (ovulation), thickening the cervical fluid and changing the lining of the uterus.

How effective is the Patch?

The patch is a very effective method of birth control. The patch is about 93% effective at preventing pregnancy in typical use, which means that around 7 out of 100 people using it as their only form of birth control will get pregnant in one year. With consistent and correct use it can be over 99% effective.

How can I get the Birth Control Patch? 

You will need to visit a clinic to get the patch or a prescription for it. You will talk with a healthcare provider about whether the patch is right for you.

When do I start my patch? 

It is recommended you start your patch right away. The patch is effective in preventing pregnancy after one week of use, so you need to use a backup method of birth control such as condoms or not have sex  for 7 days. You do not have to wait for your period, but if you happen to start on the first day of your period you don’t need to use a backup method as the patch is considered effective immediately.

How do I use the Patch? 

The patch is packaged based on a 28 day cycle.It is typically worn on the lower belly, upper arm or bum on clean, dry, lotion free skin. Your pack will contain 3 patches, each of which is worn for 7 day, for a total of 21 days. You must use all 3  patches in a row with no breaks in between. After you have used 3 patches in a row for 3 weeks:

a) remove the patch and take a short patch-free break of no more than 7 days, OR
b) remove the patch and immediately apply the 1st patch of a new pack with no break in between. 

You must be sure to apply your next patch on time and never go longer than 7 days without wearing one in order to be protected from pregnancy throughout the whole month. Periods that occur while using the patch  are a result of taking a break from hormones. Taking no hormone break or a shorter than 7 day break to lighten or skip periods is safe.

Tips for using the patch: 

  • When applying press down firmly on the patch with the palm of your hand for 10 seconds
  • Check the patch daily to ensure it is on correctly
  • Put it on a different area of skin each time to avoid irritation. If needed, you can remove the patch and put it in a new location (for example, if it is causing irritation, do not apply to skin that is irritated or cut 
  • You can exercise, swim, sweat and shower with the patch on
  • After removing a patch fold it closed on the sticky side and throw it in the garbage 
  • Do not place the patch on or near your breast/chest
  • Do not decorate or cut the patch in any way
  • Do not use tape or glue to keep the patch in place
  • Avoid directly touching the sticky surface of the patch with your fingers
  • Avoid placing patch under areas of friction (such as your waist band)
  • Avoid using any creams, lotions, or oils near or at the patch site
