Evra (The Patch)

Similar to the pill, it contains the hormones estrogen and progesterone. The Evra patch reduces pregnancy risk by releasing these hormones into the bloodstream through the skin.

These hormones:

  • Stop the ovaries from releasing an egg each month
  • Thickens cervical mucous to make it difficult for sperm to pass through
  • Changes the lining of the uterus which results in lighter periods

You must visit the sexual health clinic to see a clinic nurse.


How to use the Evra patch

  • A 1 month supply of Evra has 3 patches
  • One patch is worn for 7 days
  • Every 7 days the patch is changed for 3 weeks. For example, if you put your first patch on, on a
  • Sunday, every 7 days on a Sunday for 3 weeks you will change your patch
  • Week 4 is considered your “patch free” week
  • After 7 “patch free” days, you will start a new package and repeat the above

How to start Evra

When starting Evra, the first patch should be applied within the first 24 hours of your period If a patch wasn’t applied on the first day of your period, put it on now. This will be your patch change day and you must use a back up method of birth control (condom) for 1 week.

Where do I apply Evra?

  • The patch site should be rotated with each weekly change
  • The patch can be worn on the buttocks, pelvic area, shoulder blade, and/or upper arms
  • The patch can be worn while showering, bathing, swimming, and exercising
  • Check the patch daily to make sure that it’s in place

Forgot to change your patch?

If you are 1-2 days late changing your patch, remove and throw away the old patch and put on the new patch as soon as you remember. This will now be your new patch change day. No back up method is needed.

If you are more than 2 days late changing your patch, you may become pregnant if you have had unprotected sex. You may need the emergency contraceptive pill. Remove the old patch and put on a new patch. This will be your new patch change day and you must use a back up method for 1 week.

Keep in mind, Evra protects against pregnancy, not STD/HIV. Condoms should always be used to reduce the risk of STD/HIV.
