What is Progesterone for?

Progesterone is a natural female hormone which is found in our bodies. It is used to treat various conditions related to the menstrual cycle, including premenstrual syndrome (physical, emotional or mood change prior to a woman’s menstruation) or amenorrhoea (missing one or more periods). It is also used for abnormal uterine bleeding, female infertility, and depression that occurs after giving birth.

How to use it?

Progesterone can be taken by mouth as a capsule, inserted into the vagina as a vaginal tablet, a vaginal capsule, inserted into the vagina or rectum as a pessary or a suppository, or applied in the vagina as a gel.


For oral capsules, you should take them at bedtime on an empty stomach. Swallow the whole capsule and do not crush, chew, or break the tablet.

For suppositories, you should insert it after evacuation. Remember to remove the packaging before use.
