What is this medication for?
Fluoxymesterone belongs to a group of male sex hormones called androgens. Androgens are responsible for the growth and development of the male sex organs as well as male sex characteristics such as chest hair, facial hair, pubic hair, voice changes, and muscle growth. A deficiency of androgens can result in underdeveloped testes and/or impotence.
Fluoxymesterone is used to treat male hypogonadism (androgen deficiency in men). It is also used to treat delayed puberty in boys where it has been established that the delay is not an inherited trait.
In women who are between one and five years past menopause, fluoxymesterone is used for the treatment of certain types of breast cancers that respond to androgen treatment.
