Patch: birth control

The birth control patch only prevents pregnancy, not STIs. Always use a condom.

What is the birth control patch?

The birth control patch is a thin, plastic patch that contains two hormones (estrogen and progestin) that you place on your skin. It slowly releases the hormones through your skin.

How does the birth control patch work?

The patch prevents the ovary from releasing an egg. It also thickens the cervical mucus, making it difficult for sperm to reach the egg.

How effective is the birth control patch?

The patch is 99% effective at preventing an unplanned pregnancy when used correctly.

What are the possible side effects of the birth control patch?

• skin irritation where the patch is worn
• nausea
• breast tenderness
• moodiness
• spotting between periods
• if you smoke, the patch increases your risk of a blood clot, heart attack or stroke

What are the advantages of the birth control patch?

• you don’t have to do anything before or after sex
• you only have to change the patch once a week
• lighter and/or shorter periods
• reduced menstrual cramps
• it doesn’t affect your ability to get pregnant in the future

What are the disadvantages of the birth control patch?

• the patch is visible
• you need a prescription

Where can I get the birth control patch?

The patch can be prescribed by:

• your health care provider
• Public Health Sudbury & Districts’ Sexual Health Clinic

*The patch offers no protection against sexually transmitted infections (STIs), including HIV/AIDS.
