Oxandrolone is a man-made steroid, similar to the naturally occurring steroid testosterone. Oxandrolone is an anabolic steroid that promotes the growth of muscle tissue.
Oxandrolone is used to help you regain weight lost after surgery, severe trauma, or chronic infections. Oxandrolone is also used in people who cannot gain or maintain a healthy weight for unknown medical reasons.
Oxandrolone is also used to decrease muscle loss caused by using steroid medicines, and to reduce bone pain in people with osteoporosis.
Oxandrolone may also be used for purposes not listed in this medication guide.
You should not use oxandrolone if you have prostate cancer, advanced kidney disease, high levels of calcium in your blood, breast cancer, or if you are pregnant.
Some people using anabolic steroid medicine have developed life-threatening side effects on the liver, spleen, and blood vessels.
