Concerns about progesterone cream use
You cannot actually know how much progesterone you are getting
without having a whole-blood progesterone test. Because of this and the
following concerns, some experts are concerned about use of over-the-counter
progesterone cream.3
- If it is absorbing well.Progesterone treatment has risks. It has been linked to headaches and
dangerous blood clots in a small number of women.3
This is why progesterone is usually a prescription hormone and is not safe for
women with certain health risks.

you also need to have enough progesterone to prevent the estrogen from causing
uterine (endometrial) cancer. Using a poorly absorbed
progesterone cream while taking estrogen does not protect you from uterine
cancer.4
