• Requires a prescription from a health care provider

How does it work?

• Apply patch once a week for three weeks and then one week without a patch
• Prevents the ovaries from releasing an egg
• Thickens cervical mucus making it difficult for sperm to get through
• Causes changes in the lining of the uterus

Effectiveness

• The patch is 99.7% effective when used perfectly
• With typical use, it is 92% effective

Advantages

• Very effective and not permanent
• Only change patch once a week
• Makes periods more regular and decreases menstrual cramping
• Probably similar benefits as “the pill” but no research available yet

• Patch may partially lift off or detach from skin (this happens less than 3% of the time)
