L5.2.4.2.1.1.2: Contraceptive Patch

• A transdermal patch applied to the skin that releases synthetic estrogen and progestin hormones to prevent pregnancy

  Worn on several areas of a woman’s body, most specifically areas with larger muscles that are proximal to the reproductive tract:

  ● Lower abdomen

  ● Buttocks

  (However, it can be worn on other areas as it creates a systemic effect)
• How to use Contraceptive Patches

  Patch is worn 1 week at a time and is changed on the same week 3 times a month. The 4th week is patch-free.
• Example:

  (First 3 Weeks of November)

  1. Monday, Nov 6 (Change)
  2. Monday, Nov 13 (Change)
  3. Monday, Nov 19 (Change)

  (Last Week or 4th Week - Patch Free)

  ● Rationale: By the 4th week, there is already possible menstrual flow, as another cycle begins.
• Effectiveness

  A different site must be used each time a new patch is applied for 99% effectiveness
