Etynodiol

Etynodiol is a progestin medication which is used in birth control pills in combination with an estrogen. It is taken by mouth.

Medical uses

Etynodiol is used in combination with ethinylestradiol in birth control pills to prevent pregnancy. It works mainly by stopping the release of an egg during the menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg.

Side effects

Common side effects of etynodiol include nausea, bloating, breast tenderness, headache, change in vaginal discharge, mood swings, blurred vision, and changes in sexual desire. Serious side effects include blood clot, stroke, heart attack, and liver disease.

Pharmacology

Etynodiol is a progestogen, or an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic and glucocorticoid activity and no other important hormonal activity.

History

Etynodiol was discovered in 1954 and was introduced for medical use in 1965. It is sometimes referred to as a "first-generation" progestin.

Society and culture

Etynodiol is marketed widely throughout the world. It is available as a generic medication.
