Orilissa

Orilissa binds to the same receptors in the body as a certain hormone that stimulates the production of sex hormones.

Orilissa works by lowering blood levels of estradiol and progesterone (female sex hormones).

Orilissa is used to treat moderate to severe pain caused by endometriosis.

Take Orilissa exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Take the medicine at the same time each day, with or without food.

Your dosing schedule may change if you switch to a different strength of this medicine. Follow your doctor's dosing instructions very carefully.

Store at room temperature away from moisture and heat.

Do not keep leftover Orilissa that is no longer needed. Ask your pharmacist where to locate a drug take-back disposal program. Do not flush the unused tablets down the toilet.

Do not use Orilissa if you are pregnant. Elagolix may cause miscarriage.

Hormonal birth control methods (birth control pills, injections, implants) could make Orilissa less effective. Use a condom or diaphragm with spermicide while you are taking elagolix and for at least 1 week after your last dose.

Elagolix can lower your estrogen levels, which may cause bone loss (osteoporosis). Talk with your doctor about ways to keep your bones healthy during and after treatment with this medicine.

You should not use Orilissa if you are allergic to elagolix, or if:

• you have osteoporosis;
• you are pregnant or may become pregnant;
• you have severe liver disease; or
• you also use certain other medicines such as cyclosporine, gemfibrozil, or rifampin.

You may need to have a negative pregnancy test before starting this treatment.

Do not use Orilissa if you are pregnant, and tell your doctor right away if you become pregnant. This medicine may cause miscarriage.

Orilissa may change your menstrual periods, making it harder for you to know if you are pregnant. Other signs of pregnancy could include breast tenderness, nausea, and weight gain.

Birth control pills can make elagolix less effective. Use a condom or diaphragm with spermicide to prevent pregnancy while using elagolix and for at least 1 week after your last dose.
