Norelgestromin/ethinylestradiol, sold under the brand name Evra among others, is a type of birth control patch used to prevent pregnancy. Other benefits include the ability to determine when periods occur, improved acne, and less PMS. It is generally applied to the skin for a week at a time for three weeks, followed by a fourth week patch-free. If the patch-free interval is longer than seven days, additional birth control, such as condoms, should be used. Patches should be applied the same day of the week to altering areas of the buttock, abdomen, upper arm, or upper back.

Common side effects include headache, nausea, breast tenderness, and irregular uterine bleeding. Use is not recommended in those with liver problems, migraines with aura, or at risk of blood clots. Those at risk of blood clots include those over 35 years old who smoke. It works less well in those weighing more than 90 kg or with a BMI ≥ 30 kg/m2. It contains the progestin, norelgestromin and the estrogen, ethinylestradiol.

The combination was approved for medical use in the United States in 2001 and Europe in 2002. A generic version became available in 2014. They are used by about 0.4% of women not wanting to become pregnant in the United States. In the United States it costs about 35 USD per month as of 2024. As of 2016, the brand Ortho Evra has been discontinued in the United States while other brands continues to be marketed.
