Drostanolone Propionate

Read all of this leaflet carefully before you start using this medicine

  • Keep this leaflet. You may need to read it again.
  • 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.
  • If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet.

1.What Drostanolone Propionate is and what it is used for

Drostanolone Propionate 100 mg/ml is a clear oily solution that is injected into a muscle. It contains drostanolone, a man-made copy of a male sex hormone of the kind men's bodies make naturally, and it is not changed into the female hormone oestrogen in the body. This pack contains the short-acting form. The "propionate" part is released from the muscle quickly, so the level in your blood rises soon after an injection and falls again within a few days — which means injections are needed more often, but treatment can also be adjusted or stopped quickly. Your doctor has prescribed it for you after weighing up the benefits and the risks in your case.

2.What you need to know before you use Drostanolone Propionate

Read this section before your first injection — there are conditions in which this medicine must not be used, and others where your doctor will want to keep a close eye on you.

Do not use it if

  • Do not use this medicine if you are allergic to drostanolone propionate or to the oil it is dissolved in (see the end of this leaflet for the ingredients).
  • Do not use it if you have, or are being investigated for, cancer of the prostate gland or cancer of the male breast.
  • Do not use it if a blood test has shown a high level of calcium in your blood.
  • Do not use it if you are a woman. It can cause masculine changes, such as a permanently deeper voice, extra facial and body hair, and an enlarged clitoris.
  • Do not use it if you are pregnant, may be pregnant, or are breastfeeding.
  • Do not use it if you have severe liver or kidney disease, unless your doctor judges that you still need this treatment.

Warnings and precautions

  • Talk to your doctor before using this medicine if you have any heart or circulation problem, high blood pressure or raised cholesterol. Hormones of this type can push your cholesterol in an unhealthy direction.
  • Because this is the short-acting form, you will need injections more often than with the long-acting form. Injection sites can become sore or hard if the same area is used repeatedly, so your doctor or nurse will show you how to change the site each time.
  • Talk to your doctor if you have prostate trouble or are an older man; your prostate will normally be checked before and during treatment.
  • Tell your doctor if you have diabetes, epilepsy, migraine, or liver or kidney problems, as hormone treatment can make these harder to control.
  • Your doctor will usually arrange blood tests before you start and at intervals afterwards, to check your blood count, cholesterol, liver and prostate.
  • While you are using this medicine your body makes less of its own testosterone, and your sperm count and fertility can fall.
  • Drostanolone is prohibited in sport by the World Anti-Doping Agency. Tell your doctor if you compete at any level, as it can be detected in tests for a considerable time.
  • This medicine must not be given to children or to adolescents who are still growing, because it can stop the bones reaching their full length.

Other medicines and Drostanolone Propionate

Tell your doctor or pharmacist about any other medicines you are taking, have recently taken, or might take, including ones bought without a prescription. Be sure to mention blood-thinning medicines such as warfarin, because this injection can make them work more strongly and increase the risk of bleeding or bruising; medicines for diabetes, including insulin, because your blood sugar may drop and your doses may need to be changed; and steroid medicines of the cortisone type, such as prednisolone, which taken together with this injection can cause swelling of the ankles and legs.

Pregnancy, breastfeeding and fertility

This medicine must not be used in pregnancy. It can harm an unborn baby and can cause masculine changes in a baby girl. It must not be used while breastfeeding, as it may pass into breast milk. It is not for use in women at any time. In men, it reduces the number and quality of sperm while it is being used, which can make it harder to father a child. Because this is the short-acting form, it leaves the body faster than the long-acting form, but recovery of sperm production can still take months and is not guaranteed. Speak to your doctor if you are planning a family.

Driving and using machines

This medicine is not expected to affect your ability to drive or to use tools and machines. Some people, though, get headaches, feel dizzy, or sleep poorly and feel tired the next day. If that happens, wait until you feel normal again before driving or using machines.

3.How to use Drostanolone Propionate

Always use this medicine exactly as your doctor has told you. Ask your doctor or pharmacist if you are not sure. It is given by deep injection into a muscle, usually the buttock or the thigh, by a doctor or nurse, or by you if you have been trained to do it. It must never be injected into a vein. Inject slowly, as the solution is oily, and use a different site each time. Each ampoule is for a single use; throw away any solution left over. Because this form is short-acting, the level in your body falls quickly if an injection is missed — but do not inject extra to catch up. Contact your doctor, who will tell you what to do. If you think too much has been given, tell your doctor straight away.

4.Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Stop and get medical help straight away

  • Stop and get medical help now if you have a rash, itching, swelling of the face, lips or throat, or difficulty breathing — these may be signs of an allergic reaction.
  • Get medical help now if the injection site becomes very painful, hot, swollen or oozes fluid, or if you develop a fever — this may be an infection.
  • Get medical help now if you have chest pain, sudden breathlessness, coughing, or feel faint straight after an injection.
  • Get medical help now if your skin or the whites of your eyes turn yellow, your urine becomes dark, or you have pain under your right ribs.
  • Get medical help now if you cannot pass urine, or if there is blood in your urine.
  • Tell your doctor promptly if your mood drops severely, you become unusually aggressive, or you have thoughts of harming yourself.

Other possible side effects

  • Soreness, stinging, redness or a hard lump at the injection site, which is more common with this short-acting form
  • Oily skin and acne on the face, chest or back
  • Hair loss from the scalp in a male pattern, and increased hair on the body and face
  • Trouble sleeping, restlessness, irritability or mood swings
  • Increase or decrease in sex drive
  • Shrinking of the testicles and a lower sperm count during treatment
  • Headache, flushing, or a feeling of the heart pounding
  • Unhealthy changes in cholesterol, and sometimes a rise in blood pressure, usually picked up on a check-up
  • In men, needing to pass urine more often at night or finding it harder to start

5.How to store Drostanolone Propionate

Keep this medicine out of the sight and reach of children. Store below 25 °C and do not freeze. Keep the ampoules inside the outer carton to protect them from light until the moment of use. Do not use the medicine after the expiry date shown on the carton and the ampoule; that date is the last day of the month stated. Do not use an ampoule that is cracked or chipped, or if the liquid looks cloudy or contains particles. Do not throw medicines away in household rubbish or down the sink. Take unused ampoules back to your pharmacist, and put used ampoules and needles into a sharps container. This helps protect the environment.
