Ethinyl estradiol

Pronounced ETH-i-nil es-trah-DY-ol

Brand names: In many combined pills, patches, and rings

Type: Estrogen (contraceptive component) · All Women's Health Medicines

What Ethinyl estradiol is used for

  • Birth control, as the estrogen part of combined pills, patches, and rings
  • Cycle control and acne (in approved combined products)

◆ Kidney note

Blood pressure can rise slightly on estrogen contraception, which matters in kidney disease where blood pressure control is central.

Common side effects

  • Nausea
  • Breast tenderness
  • Headache
  • Breakthrough bleeding
  • Mood changes

Important cautions

  • Estrogen-containing contraception raises the risk of blood clots in the legs, lungs, and brain — risk is highest in smokers over 35, who should not use it
  • It must not be used with certain migraine with aura, uncontrolled blood pressure, or a history of estrogen-sensitive cancer — screening questions come first
