Rubraca is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Rubraca is used to treat ovarian cancer, fallopian tube cancer, or primary peritoneal cancer (cancer of the membrane lining the organs inside your abdomen). Rubraca is sometimes used for these conditions only if your cancer has a specific genetic marker (an abnormal "BRCA" gene). Your doctor will test you for this gene.

Rubraca is also used to treat prostate cancer with an abnormal BRCA gene. It is given for this condition when the cancer has spread to other parts of the body and surgery or other cancer treatments did not work or have stopped working.

Rubraca was approved for prostate cancer by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, some people responded to this medicine, but further studies are needed.

Rubraca can cause leukemia or serious bone marrow problems. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, blood in your urine or stools, shortness of breath, or signs of infection (fever, feeling weak or tired, weight loss).

Take Rubraca exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Rubraca is usually taken once every 12 hours, with or without food.

If you take Rubraca for prostate cancer, you may also be treated with another medicine called a gonadotropin-releasing hormone, or GnRH. GnRH helps prevent the testicles from producing testosterone.

If you vomit shortly after taking a dose of this medicine, do not take another dose. Wait until your next scheduled dose to take the medicine again, but do not take 2 doses at the same time.

You may need frequent medical tests and your cancer treatments may be delayed based on the results.

Store at room temperature away from moisture and heat.

Using Rubraca may increase your risk of developing serious bone marrow problems or other types of cancer, such as leukemia. Ask your doctor about your specific risk.
