- If you have any further questions, ask your doctor or pharmacist.
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

1.What Oxymetholone is and what it is used for
Oxymetholone is a man-made medicine related to testosterone, the main male sex hormone. It works mainly by encouraging your bone marrow — the factory inside your bones — to make more red blood cells, the cells that carry oxygen around your body. Your doctor has prescribed it because your bone marrow is not producing enough red blood cells, a problem called anaemia, which can happen when the marrow fails or is damaged. It is a strong medicine that needs close supervision, and it has been chosen for your situation only.
2.What you need to know before you use Oxymetholone
Read this section carefully before your first tablet — this medicine needs regular blood tests and you should know what to watch for.
Do not use it if
- Do not use it if you are allergic to oxymetholone or to any of the other ingredients listed on your carton.
- Do not use it if you are pregnant, may be pregnant or are breastfeeding — it can seriously harm an unborn baby.
- Do not use it if you have cancer of the prostate gland or cancer of the male breast.
- Do not use it if you have severe liver disease, or have ever been told you have a liver tumour.
- Do not use it if you have too much calcium in your blood.
- Do not use it if you have severe heart failure or severe kidney disease with a lot of protein in your urine.
Warnings and precautions
- Talk to your doctor before using it if you have any liver trouble. Of all the hormone tablets of this kind, oxymetholone is the hardest on the liver: it can cause blood-filled spaces in the liver, and rarely liver tumours, which sometimes do not cause any symptoms until they bleed. Your doctor will test your liver before you start and regularly during treatment. Tell your doctor immediately if your skin or eyes turn yellow, your urine goes dark, your stools go pale, or you get pain in the upper right side of your stomach.
- Talk to your doctor before using it if you have heart failure, high blood pressure or kidney disease. This medicine makes the body hold a lot of salt and water, which can cause sudden swelling and put strain on the heart. Weigh yourself regularly and tell your doctor about rapid weight gain.
- Your doctor will take blood counts regularly, both to see whether the anaemia is improving and because this medicine can affect how your blood clots.
- Your blood fats and blood sugar will be checked, because this medicine lowers your "good" cholesterol and can unmask or worsen diabetes.
- If this medicine is for a child, the doctor will X-ray the bones regularly, because it can close the growing ends of the bones too early and reduce final adult height.
- Women should tell the doctor as soon as their voice deepens, hair appears on the face or body, or their periods change — some of these changes can be permanent.
- Never take this medicine to build muscle or improve sporting performance and never give it to anyone else; used that way it is particularly dangerous to the liver.
Other medicines and Oxymetholone
Tell your doctor or pharmacist about all other medicines you take, including anything bought without a prescription and herbal products. It especially matters with: blood-thinning medicines such as warfarin — oxymetholone makes them far stronger and can cause serious bleeding, so your doctor will usually reduce the dose and check your clotting tests often; medicines for diabetes, including insulin, because your blood sugar can fall; steroid tablets such as prednisolone, which together with this medicine cause much more swelling; and ciclosporin, used after transplants.
Pregnancy, breastfeeding and fertility
Do not take this medicine if you are pregnant or trying to become pregnant. It can seriously harm an unborn baby, especially the sexual development of a baby girl. Women who could become pregnant must use a reliable method of contraception; ask your doctor which is suitable. Do not breastfeed while taking it. In men, this medicine lowers the number of sperm you make and can make you unable to father a child during treatment, and sometimes for a while afterwards.
Driving and using machines
Oxymetholone is not expected to affect your ability to drive or to use tools and machines. If you feel dizzy, tired or headachy, or you are sleeping badly, do not drive or use machines until you feel normal again.
3.How to use Oxymetholone
Always take this medicine exactly as your doctor has told you; check with your doctor or pharmacist if you are unsure. Swallow the tablets whole with a glass of water, ideally with or just after food to reduce stomach upset. Your doctor decides how many tablets you take and for how long, based on your blood counts, and this is written on your pharmacy label — never change it yourself. It can take three to six months of treatment before the full benefit is seen, so keep taking the tablets even if you do not feel different at first. If you forget a dose, take it when you remember unless the next one is nearly due, in which case skip it; never take a double dose. Do not stop without talking to your doctor. If you take too many tablets, contact your doctor or your nearest hospital straight away and take the carton with you.
