Oxandrolone may increase the amount of low density lipoprotein (LDL; 'bad cholesterol') and decrease the amount of high density lipoprotein (HDL; 'good cholesterol') in your blood. This may increase your risk of developing heart disease. Tell your doctor if you or anyone in your family has or has ever had high cholesterol, heart disease, a heart attack, chest pain, or a stroke. Also tell your doctor if you smoke or have ever smoked and if you have high blood pressure or diabetes.

It is important to have regular laboratory tests to be sure that the liver is working properly and that LDL has not increased.
