Interferon beta-1a injection is used to treat the relapsing forms of multiple sclerosis (MS). Interferon beta-1a will not cure MS, but it may slow some of the disabling effects and decrease the number of relapses of the disease. Interferons are natural substances that are produced in the body to help fight infections. Interferon beta-1a is a synthetic (man-made) version of these substances.

Interferon beta-1a is available only with your doctor's prescription.

Leuprolide overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily. Leuprolide reduces the amount of testosterone in men or estrogen in women.

Leuprolide is used in men to treat the symptoms of prostate cancer (but does not treat the cancer itself). Leuprolide is used in women to treat symptoms of endometriosis (overgrowth of uterine lining outside of the uterus) or uterine fibroids.

Leuprolide is also used to treat precocious (early-onset) puberty in both male and female children.

Leuprolide may also be used for purposes not listed in this medication guide.
