What is Oxandrolone?
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.
Warnings
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. These conditions can occur without warning or symptoms and can lead to liver failure, internal bleeding, cancer, stroke, heart attack, or death. Talk with your doctor about the risks and benefits of using this medicine.
How should I take Oxandrolone
Oxandrolone is usually given for only a few weeks. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Oxandrolone will not enhance athletic performance and should not be used for that purpose.
Oxandrolone may be habit-forming. Never share oxandrolone with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
If a child is taking this medicine, tell your doctor if the child has any changes in weight. Oxandrolone doses are based on weight in children.
While using oxandrolone, you will need frequent blood tests. Your kidney function may also need to be checked with urine tests.
Oxandrolone can cause bone overgrowth in children, especially young children. Bone development may need to be checked with x-rays every 6 months during treatment.
Store at room temperature away from moisture and heat.
Keep track of the amount of medicine used from each new bottle. Oxandrolone is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

Some people using anabolic steroid medicine have developed cysts or tumors of the liver or spleen. These conditions can occur without warning or symptoms and can lead to liver failure, internal bleeding, cancer, or death. Using anabolic steroid medicine may also cause cholesterol (lipid) changes within your blood, which can increase fatty buildup inside your arteries (also called atherosclerosis). This condition can lead to stroke or heart attack. Talk with your doctor about the risks and benefits of using oxandrolone.
To make sure oxandrolone is safe for you, tell your doctor if you have:
-
liver disease;
-
a history of heart disease;
-
high cholesterol or triglycerides (a type of fat in the blood);
-
diabetes;
-
a thyroid disorder;
-
chronic obstructive pulmonary disease (COPD);
-
a history of stroke or blood clots;
-
if you take a blood thinner (warfarin, Coumadin, Jantoven); or
-
if you use other steroid medicines (prednisone, methylprednisolone, and others).
oxandrolone can harm an unborn baby or cause birth defects. Do not use if you are pregnant. Use effective birth control and tell your doctor right away if you become pregnant during treatment.
It is not known whether oxandrolone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Older men may have an increased risk of developing an enlarged prostate or prostate cancer while taking this medicine. Talk with your doctor about your individual risk.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
What special dietary instructions should I follow?
Unless your doctor tells you otherwise, continue your normal diet.
What should I avoid while using Oxandrolone?
Follow your doctor's instructions about any restrictions on food, beverages, or activity.
