Different forms of progesterone are available by prescription. Progesterone is often used in:

  • Birth control pills
  • Hormone replacement therapy (either as pills or applied to the skin)

Many plants contain compounds related to progesterone. It's possible to buy products made from plant progesterone without a prescription.

A form of progesterone made from plants is also available as a skin cream without a prescription.

This article focuses on progesterone that's available without a prescription -- not the drug form of progesterone that requires a prescription.

Why do people use progesterone?

Over-the-counter progesterone cream has been marketed as a treatment for menopausal symptoms, including:

  • Hot flashes
  • Memory loss
  • Fatigue
  • Tender breasts

It's also sometimes used by people to try to treat:

  • Thyroid problems
  • Osteoporosis
  • Weight gain

The progesterone in these creams can effectively travel through the skin and into the bloodstream, according to research. In one study, menopausal women used 40 milligrams of cream twice daily, placing it on their arm, thigh, breast, or abdomen. Their blood levels of progesterone were as high as when they took progesterone capsules by mouth.

Can you get progesterone naturally from foods?

Many plants make progesterone. The progesterone in creams bought without a prescription is made by processing ingredients from plants, such as yams.
