Crinone (progesterone, micronized)

No dosing information is available for this tab.

Progesterone is administered by orally, intravaginally, and by IM injection.

Progesterone capsules are administered orally once daily at bedtime. Women who have difficulty swallowing the capsules should be advised to swallow progesterone capsules while in an upright position and with adequate amounts of fluid (e.g., a glass of water). Administration at bedtime may alleviate some of the adverse effects (e.g., dizziness, blurred vision) associated with the drug.

Progesterone vaginal gel should not be administered concurrently with other intravaginal preparations. If therapy with another agent administered intravaginally is needed, such therapy should be administered 6 hours before or 6 hours after progesterone vaginal gel.

Concomitant use of progesterone vaginal inserts with other preparations that are administered intravaginally is not recommended. Although specific studies have not been undertaken, the possibility exists that concomitant administration of a progesterone vaginal insert with another preparation administered intravaginally may alter the release and absorption of progesterone from the vaginal insert.

Progesterone is used to support embryo implantation and maintain pregnancy as a component of assisted reproductive technology (ART) treatment in infertile women. Such use is associated with increased ongoing pregnancy rates.

Although progestins have been used beginning in the first trimester of pregnancy to prevent habitual abortion or to treat threatened abortion, there is no adequate evidence from well-controlled studies to substantiate the efficacy of progestins for these uses; however, there is evidence of potential adverse effects on the fetus when these drugs are administered during the first 4 months of pregnancy. In addition, in most women, the cause of abortion is a defective ovum, which progestins could not be expected to influence. Because of their uterine-relaxant effects, progestins may delay spontaneous abortion of fertilized defective ova. Masculinization of the female fetus has reportedly occurred when progestins were used during pregnancy. Clitoral hypertrophy has been reported in a few female neonates born to women who had received medroxyprogesterone during pregnancy. An association between intrauterine exposure to female sex hormones and congenital anomalies, including cardiovascular and limb defects, has been suggested. (See Cautions: Pregnancy, Fertility, and Lactation, in Estrogen-Progestin Combinations 68:12.) Use of progestins generally is not recommended during the first 4 months of pregnancy.

Progesterone should not be used to induce withdrawal bleeding as a test for pregnancy.

Progestins are reportedly distributed into milk. The manufacturers warn that the possible effects of progestins in milk on nursing infants have not been determined.
