These side effects may go unnoticed until life-threatening liver failure or internal bleeding develops. These side effects often stop or reverse when the medicine is stopped. Oxandrolone may also cause blood lipid (fat) changes that may increase the risk of hardening of the arteries and certain heart/blood vessel diseases (coronary artery disease).


Oxandrolone is used for:

Promoting weight gain, in combination with other medicines, after weight loss due to major surgery, recurring infections, serious injury, or unknown reasons. It is also used to offset certain side effects of long-term steroid use (protein catabolism), or to relieve bone pain due to osteoarthritis. It may also be used for other conditions as determined by your doctor.
