Deca-Durabolin is an injectable anabolic preparation. The decanoate ester gives the preparation a duration of action of about 3 weeks after injection.
Nandrolone is chemically related to the male hormone. Compared to testosterone, it has an enhanced anabolic and a reduced androgenic activity. This has been demonstrated in animal bioassays and explained by receptor-binding studies. The low androgenicity of nandrolone is confirmed in clinical use.
In humans, Deca-Durabolin has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis. In women with disseminated mammary carcinoma, Deca-Durabolin has been reported to produce objective regressions for many months. Furthermore, Deca-Durabolin has nitrogen-saving action. This effect on protein metabolism has been established by metabolic studies and is utilized therapeutically in conditions where a protein deficiency exists eg, during chronic debilitating diseases and after major surgery and severe trauma. In these conditions, Deca-Durabolin serves as a supportive adjunct to specific therapies and dietary measures as well as parenteral nutrition.
Androgenic effects (eg, virilisation) are relatively uncommon at the recommended dosages. Nandrolone lacks the C-17α-alkyl group which is associated with the occurrence of liver dysfunction and cholestasis.

What Deca-Durabolin is used for

It is used to treat:

- certain types of anaemia
- breast cancer (in women)
- patients on long term corticosteroids.
It belongs to a group of medicines known as anabolic steroids.
These medicines help to rebuild tissues that have become weak because of continuing illness or serious injury. Deca-Durabolin can be used to increase lean body mass in the case of negative nitrogen balance. It can also be used to increase bone mass and stimulate the formation of red blood cells in the bone marrow.
Your doctor may have prescribed it for another reason.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Ability to drive or operate machinery.
As far as is known, Deca-Durabolin has no adverse effect on driving and using machines.
Before you use Deca-Durabolin
Do not use Deca-Durabolin if:
- you are a man and have or have had cancer of the prostate or the breast,or are suspected of having one of these tumours. You also should have had an examination by your physician to exclude any abnormalities of the genital organs.
- you have kidney disease
- you have liver disease
- you have heart failure
- you are allergic to nandrolone decanoate, or any of the ingredients listed at the end of this leaflet
- you are allergic to peanuts or soya
- you are a child below the age of 3 years
- it is past the expiry date or the packaging shows signs of tampering.
Do not use this medicine if you are pregnant or think you may be pregnant.
It may give increased male characteristics to an unborn baby and should not be used during pregnancy.
Do not breastfeed if you are using this medicine.
It may have a virilising effect on your baby and the amount of active ingredient excreted in breast milk is unknown.
The acute toxicity of nandrolone decanoate in animals is very low. There are no reports of acute overdosage with Deca-Durabolin in humans.
Known or suspected prostatic carcinoma or mammary carcinoma in the male.
Use in pregnancy & lactation: Deca-Durabolin is contraindicated during pregnancy because of possible masculinisation of the foetus. There are insufficient data on the use of this medicine during breastfeeding to assess potential harm to the infant or a possible influence on milk production.
If signs of virilisation develop, discontinuation of the treatment should be considered, preferably in consultation with the patient.
It is recommended to monitor patients with any of the following conditions: Latent or overt cardiac failure, renal and hepatic dysfunction, hypertension, epilepsy, diabetes or migraine (or a history of these conditions), since anabolic steroids may occasionally induce fluid retention; incomplete statural growth, since anabolic steroids in high dosages may accelerate epiphyseal closure; skeletal metastases of breast carcinoma. In these patients, hypercalcaemia may develop both spontaneously and as a result of anabolic steroid therapy. The latter can be indicative of a positive tumour response to the hormonal treatment. Nevertheless, the hypercalcaemia should first be treated appropriately and after restoration of normal calcium levels, hormone therapy can be resumed; liver dysfunction.The use of anabolic steroids to enhance athletic ability may carry severe risks to the user’s health and should be discouraged.

The use of anabolic steroids like Deca-Durabolin may lead to a reduction of the doses of these medicines.
Also tell your doctor or pharmacist if you are using or about to use the hormone ACTH or corticosteroids (used to treat various conditions such as rheumatism, arthritis, allergic conditions and asthma). The use of anabolic steroids like Deca-Durabolin may increase the risk of water retention especially if your heart and liver are not working properly.
Anabolic steroids may also affect the results of some laboratory tests (e.g. thyroid gland). Therefore you must tell your doctor or the laboratory staff performing the tests that you are using this medicine.
These medicines may be affected by Deca-Durabolin or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Additionally, at regular intervals, blood tests will be done to check the oxygen-carrying substance in your red blood cells (hemoglobin). In very rare cases the number of red blood cells will increase too much leading to complications.
Things that may help your condition
Some self help measures may help your condition. Your doctor or pharmacist can give you more information.
Your doctor may advise you to change your diet. This is because Deca-Durabolin works best in helping to repair and replace your damaged tissue, bone or red blood cells when you are eating a high protein, and nutritious diet.
