There is a case report of progesterone misuse with an oral dosage of 6,400 mg per day. [137] Administration of as much as 500 mg progesterone by intravenous infusion in humans was uneventful in terms of toxicity, but did induce deep sleep, though the individuals were still able to be awakened with sufficient stimulation. [119] [17] [120] [121]
Progesterone is used as part of hormone replacement therapy in people who have low progesterone levels, and for other reasons. For purposes of comparison with normal physiological circumstances, luteal phase levels of progesterone are 4 to 30 ng/mL, while follicular phase levels of progesterone are 0.02 to 0.9 ng/mL, menopausal levels are 0.03 to 0.3 ng/mL, and levels of progesterone in men ...
MPA has been studied at "massive" dosages of up to 5,000 mg per day orally and 2,000 mg per day via intramuscular injection, without major tolerability or safety issues described. [ 122 ] [ 123 ] [ 124 ] Overdose is not described in the Food and Drug Administration (FDA) product labels for injected MPA (Depo-Provera or Depo-SubQ Provera 104).
The duration of progestogen therapy should be at least 14 days per cycle to prevent endometrial disease. [52] Endometrial cancer has been grouped into two forms in the context of hormone replacement. Type 1 is the most common, can be associated with estrogen therapy, and is usually low grade.
Two types of female oral contraceptive pill, taken once per day, are widely available: The combined oral contraceptive pill contains estrogen and a progestin; colloquially known as "the Pill". The progestogen-only pill, colloquially known as "minipill". For perfect use it is 99% effective and typical use is 91% effective.

Norgestimate is a progestogen, or an agonist of the progesterone receptor. [1] The relative binding affinities of norgestimate and its active metabolites for the progesterone receptor compared to promegestone (100%) are 15% for norgestimate, 10% for norelgestromin, 150% for levonorgestrel, and 135% for levonorgestrel acetate.

Estradiol/progesterone (TX-001HR), a combination of estradiol and progesterone in oil-filled capsules, is currently pending approval. [45] Estradiol and norgestimate (Prefest; 1 mg / 90 μg) was previously available in the U.S. but was discontinued.
