What Is Progesterone Injection?
Progesterone injection is a type of female hormone given to replace the hormone progestin when the body is not making enough of it.

Progesterone is also used to treat abnormal bleeding from the uterus that is due to low hormone levels and not other causes (e.g., fibroids, cancer of the uterus). Progesterone injection is available in generic form.
