Progestin

How is Progestin dosed?

Progestins can be dosed in various ways, depending on the specific form and intended use. For oral progestins, the typical dosages are as follows:

  • For preventing endometrial hyperplasia when taking estrogen for ovarian hormone therapy in postmenopausal women: 200 mg per day at bedtime for 12 continuous days per 28-day cycle of estrogen treatment each month.
  • For treating amenorrhea: 400 mg per day at bedtime for ten days.

For vaginal progestins, the dosages are:

  • For treating amenorrhea: 45 mg (one applicatorful of 4% gel) once every other day for up to six doses. Dose may be increased to 90 mg (one applicatorful of 8% gel) once every other day for up to six doses if needed.
  • For use with infertility procedures: 90 mg (one applicatorful of 8% gel) one or two times a day. If pregnancy occurs, treatment can continue for up to ten to twelve weeks.

For parenteral progestins (e.g., injections), the dosages are typically based on the individual's age, medical condition, and the specific progestin used. It is crucial to follow your doctor's instructions and dosage recommendations as they may vary based on individual factors.
