Fluoxymesterone is used to treat symptoms of low testosterone in adult men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Fluoxymesterone is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain) or hypothalamus (a part of the brain) that cause hypogonadism. Fluoxymesterone is also used to stimulate puberty in men with delayed puberty. Fluoxymesterone may also be used alone or along with other medications in certain women with breast cancer that has spread to other parts of the body and can not be removed with surgery. Fluoxymesterone is in a class of medications called androgenic hormones. It works by supplying testosterone to replace the testosterone that is normally produced naturally in the body. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. When used to treat breast cancer, testosterone works by blocking the release of estrogen to stop or slow the growth of breast cancer..

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
