Firmagon is a brand-name medication that contains the active ingredient degaralix. It’s a synthetic hormone blocker that reduces testosterone production, and it’s approved to treat advanced prostate cancer.

Firmagon shouldn’t be prescribed during pregnancy, although it typically isn’t prescribed in people who can become pregnant. It may also impact fertility and the ability to become pregnant.

According to Firmagon’s prescribing information, no studies have been done in pregnant humans taking Firmagon. However, in animal studies, Firmagon can cause harm to a fetus or even pregnancy loss.

Firmagon only has approval from the Food and Drug Administration (FDA) to treat prostate cancer by reducing testosterone. There is some research indicating that degarelix, the active ingredient in Firmagon, may have use in breast cancer treatment by suppressing ovarian function.

However, research is limited, and this would be considered an off-label use. Firmagon is not typically prescribed to people who can become pregnant, and the drug’s prescribing information warns against prescribing the drug in people who are or may become pregnant.

Firmagon can also impact your fertility, regardless of your gender. In animal studies, females showed decreased fertility after treatment, whereas males experienced reversible infertility after one dose.

However, the majority of prostate cancer treatments can have some effect on fertility. Doctors generally weigh up the risks and benefits of a treatment before prescribing it, and the benefits of treating prostate cancer most often outweigh the risks of infertility.

Speak with a doctor or pharmacist if you have been prescribed Firmagon and wish to conceive a child. They may be able to advise you of other options before you start treatment. You can also learn more about other treatments for prostate cancer.
