Oxandrolone is a man-made anabolic steroid. Because it is anabolic it also promotes the growth of muscle tissue.

The steroid is used with a diet program to cause weight gain in people who have lost too much weight due to surgery, injury, chronic (long-lasting) infections, trauma, or who are underweight for unknown reasons.

Oxandrolone is also used to treat bone pain in people with osteoporosis and to prevent certain side effects in people who take corticosteroids for a long time.

Withdrawn by FDA in 2023

Food and Drug Administration (FDA) in the USA decided to pull the medication from the market in the USA. FDA believes that the potential problems associated with oxandrolone tablets are sufficiently serious that the drug should be removed from the market.

Oxandrin was approved by the FDA in 1964 to relieve bone pain in osteoporosis. However, in 1984 an FDA advisory committee concluded there was no evidence of efficacy for tablets.

Oxandrolone and similar medications may cause damage to the liver or spleen and liver cell tumors - sometimes fatal. Blood lipid changes that are known to be associated with increased risk of atherosclerosis.
