Oxymetholone is an anabolic steroid, which is a man-made form of a hormone similar to testosterone. Oxymetholone is used to treat certain types of anemia (lack of red blood cells), including anemia caused by chemotherapy. Oxymetholone will not enhance athletic performance and should not be used for that purpose.
You should not use this medicine if you have severe liver or kidney disease, prostate cancer, male breast cancer, or female breast cancer with high levels of calcium in the blood. Do not use oxymetholone if you are pregnant.
Long-term use of oxymetholone can cause liver tumors or blood-filled cysts in your liver or spleen. Call your doctor at once if you have upper stomach pain, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes), or rapid weight gain (especially in your face and midsection).
