What Are Ethinyl Estradiol and Norelgestromin Used For?

Ethinyl estradiol and norelgestromin are two synthetic hormones combined in a transdermal patch to prevent pregnancy and manage menstrual-related issues. This combination patch delivers a steady dose of estrogen (ethinyl estradiol) and progestin (norelgestromin) through the skin, reducing the risk of ovulation and creating an environment hostile to sperm.

How Do They Work?

• Inhibit ovulation
  The hormones suppress the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), preventing egg development and release.
• Thicken cervical mucus
  Thicker mucus makes it harder for sperm to reach the uterus.
• Alter endometrial lining
  Changes in the uterine lining reduce the chance of implantation.

How to Use the Patch

1. Choose a site on clean, dry, intact skin—lower abdomen, buttock, upper torso (excluding breasts), or outer arm.
2. Apply a new patch on the same day each week for three consecutive weeks.
3. Remove the patch after seven days, then start the next patch immediately if it’s in Week 1–2. In Week 4 (patch-free), expect withdrawal bleeding.
4. Rotate sites to reduce skin irritation.
5. If it peels off: Reapply if <24 hours; replace with a new patch if >24 hours and use backup contraception for 7 days.
