PROGESTERONE SUPPORT MEDICINES

Progesterone plays a vital role in preparing your womb for embryo implantation and supporting early pregnancy. As part of your treatment, you may be prescribed one of several forms of progesterone.

Progesterone medicines used in fertility treatment

Here we’ve outlined the different progesterone medicines you may be prescribed. Each section explains what it’s for, how to use it, possible side effects, and when to contact us if something doesn’t feel right. 

The progesterone medicine prescribed for you will depend on your individual treatment plan and medicine availability. Always use your medicine exactly as directed by your Care Fertility team and as shown in your treatment companion app, Salve. Information about recently used medicines may remain on this page for patients who are completing an existing course of treatment.

If anything is unclear, or you’re worried about how you’re feeling, our team is always here to help.
