The duration of treatment depends on the clinical response and the possible occurrence of side-effects.
We would recommend that the effectiveness of therapy be monitored with the appropriate methods for osteoporosis on a 6-12 monthly basis.
Method of administration:
DecaDuralin should be administered by deep intramuscular injection

4.3 Contraindications

Pregnancy (see section 4.6).
Breast-feeding
Porphyria
Hypersensitivity to the active substance or to any of the excipients, including arachis oil.DecaDuralin is therefore contraindicated in patients allergic to peanuts or soya (see section 4.4).

4.4 Special warnings and precautions for use
Medical examination:

Physicians should consider monitoring patients receiving DecaDuralin before the start of treatment, at quarterly intervals for the first 12 months and yearly thereafter for the following parameters:
• Hematocrit and hemoglobin to exclude polycythemia.
Conditions that need supervision:
Patients, especially the elderly, with the following conditions should be monitored for:
• Tumours – Mammary carcinoma, hypernephroma, bronchial carcinoma and skeletal metastases. In these patients hypercalcaemia or hypercalciuria may develop spontaneously, and also during androgen therapy. Nevertheless, the hypercalcaemia or hypercalciuria should first be treated appropriately and after restoration of normal calcium levels, if judged necessary and taking into account the risks and benefits on a case by case basis, hormone therapy can be resumed, with caution.
• Pre-existing conditions-In patients with pre-existing cardiac, renal or hepatic insufficiency/disease or epilepsy or migraine anabolic steroid treatment may cause complications characterized by oedema with or without congestive heart failure. In such cases treatment must be stopped immediately. Patients who experienced myocardial infarction, cardiac-, hepatic- or renal insufficiency, hypertension, epilepsy, or migraine should be monitored due to the risk of deterioration of or reoccurrence of disease. In such cases treatment must be stopped immediately.
• Diabetes mellitus – DecaDuralin can improve glucose tolerance in diabetic patients (see section 4.5).
• Anti-coagulant therapy – DecaDuralin can enhance the anti-coagulant action of coumarin-type agents (see also section 4.5).
• Liver dysfunction – caution should be used in patients with severe hepatic impairment and DecaDuralin 50mg/ml should only be used if the benefits outweigh the risks.
Adverse events:
If anabolic steroid-associated adverse reactions occur (see section 4.8), treatment with DecaDuralin should be discontinued and, upon resolution of complaints, treatment can be resumed.
Virilisation:
Patients should be informed about the potential occurrence of signs of virilisation. In particular, singers and women with speech professions should be informed about the risk of deepening of the voice.
If signs of virilisation develop, the risk/benefit ratio has to be newly assessed with the individual patient.
(Mis) use in sports:
Nandrolone is classified as a prohibited substance under the Olympic Movement Anti- doping Code (OMAC 1999). The misuse of Nandrolone and other anabolic steroids to enhance ability in sports carries serious health risks and is to be discouraged.
Excipients:
DecaDuralin contains arachis oil (peanut oil) and should not be taken/applied by patients known to be allergic to peanut. As there is a possible relationship between allergy to peanut and allergy to soya, patients with soya allergy should also avoid DecaDuralin (see section 4.3).
DecaDuralin 50mg/ml contains 100 mg benzyl alcohol per ml solution and must not be given to premature babies or neonates. Benzyl alcohol may cause anaphylactoid reactions in infants and children up to 3 years old.
Paediatric Population:
Safety and efficacy have not been adequately determined in children and adolescents. In pre-pubertal children statural growth and sexual development should be monitored since anabolic steroids in general and DecaDuralin in high dosages may accelerate epiphyseal closure and sexual maturation.

4.5 Interaction with other medicinal products and other forms of interaction

Enzyme-inducing agents may decrease and enzyme-inhibiting drugs may increase nandrolone levels. Therefore, adjustment of the dose of DecaDuralin may be required.
Insulin and other anti-diabetic medicines:
Anabolic steroids may improve glucose tolerance and decrease the need for insulin or other anti-diabetic drugs in diabetic patients (see section 4.4). Patients with diabetes mellitus should therefore be monitored especially at the beginning or end of treatment and at periodic intervals during DecaDuralin treatment.
Anti-coagulant therapy:
High doses of DecaDuralin may enhance the anti-coagulant action of coumarin- type agents (see section 4.4). Therefore close monitoring of prothrombin time and if necessary a dose reduction of the anti-coagulant is required during therapy.
ACTH or corticosteroids:
The concurrent administration of anabolic steroids with ACTH or corticosteroids may enhance edema formations; thus these active substances should be administered cautiously, particularly in patients with cardiac or hepatic disease or in patient predisposed to edema (see section 4.4).
Laboratory test interactions:
Anabolic steroids may decrease levels of thyroxine-binding globulin resulting in decreased total T4 serum levels and increases resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.
Recombinant Human Erythropoietin:
Combination of DecaDuralin with rhEPO (recombinant human erythropoietin), especially in females, may enable a reduction of the erythropoietin dose to reduce anemia.

4.6 Pregnancy, lactation and fertility

DecaDuralin is contra-indicated in women who are pregnant (see section 4.3).
Pregnancy
There are no adequate data for the use of DecaDuralin in pregnant women. In view of the risk of virilisation of the foetus, DecaDuralin should not be used during pregnancy. Treatment with DecaDuralin should be discontinued when pregnancy occurs.
Lactation:
There are no adequate data for the use of this medicine during lactation to assess potential harm to the infant or a possible influence on milk production. Therefore, DecaDuralin should not be used during lactation.
Fertility:
In men treatment with DecaDuralin can lead to fertility disorders by repressing sperm-formation. In women treatment with androgens can lead to an infrequent or repressed menstrual cycle (see section 4.8).

4.7 Effects on ability to drive and use machines

DecaDuralin has no influence on the ability to drive and use machines.

4.8 Undesirable effects

Due to the nature of DecaDuralin, side effects cannot be quickly reversed by discontinuing medication. Injectables in general, may cause local reaction at the injection site.
DecaDuralin at the recommended dosages is unlikely to produce virilising effects. High dosages, prolonged treatment and/or too frequent administration may cause:
System Organ Class MedDRA term*
Endocrine disorders Virilism
Metabolism and nutrition disorders Lipids abnormal1
Psychiatric disorders Libido increased
Vascular disorders Hypertension
Respiratory, thoracic and mediastinal disorders Dysphonia
Gastrointestinal disorders Nausea
Hepatobiliary disorders Hepatic function abnormal
Peliosishepatis
Liver tumours
Skin and subcutaneous tissue disorders Acne
Pruritus
Hirsutism
Renal and urinary disorders Urine flow decreased
Reproductive system and breast disorders Enlarged clitoris
General disorders and administration site conditions Oedema
Injection site reaction
Sodium retention
Investigations Haemoglobin increased
* MedDRA version 15.0.
1. Decrease in serum LDL-C, HDL-C and triglycerides.
Virilisation which appears in sensitive women as hoarseness, acne, hirsutism and increase of libido. Hoarseness may be the first symptom of vocal change which may end in long-lasting, sometimes irreversible deepening of the voice.
The terms used to describe the undesirable effects above are also meant to include synonyms and related terms.

4.9 Overdose

The acute toxicity of nandrolonedecanoate in animals is very low. There are no reports of acute overdosage with DecaDuralin in the human.

5. Pharmacological properties

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Anabolic steroids. ATC code: A14A B01
Nandrolone is chemically related to testosterone and shows enhanced anabolic and a reduced androgenic activity.
In humans DecaDuralin has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis.
Androgenic effects (e.g. virilisation) are relatively uncommon at the recommended dosages. Nandrolone lacks the C17 alpha-alkyl group which is associated with the occurrence of liver dysfunction and cholestasis.

5.2 Pharmacokinetic properties

Absorption
Nandrolonedecanoate is slowly released from the injection site into the blood with a half-life of 6 days.
Distribution
The ester is rapidly hydrolysed to nandrolone in the blood with a half-life of one hour or less. The half-life for the combined process of hydrolysis of nandrolonedecanoate and of distribution and elimination of nandrolone is 4.3 hours.
Biotransformation and excretion
Nandrolone is metabolised by the liver. 19-norandrosterone, 19-noretiocholanolone and 19-norepiandrosterone have been identified as metabolites in the urine. It is not known whether these metabolites display a pharmacological action.

5.3 Preclinical safety data

Toxicity studies in animals after repeated dosing did not indicate a safety risk for humans. No formal studies to assess reproduction toxicity, genotoxicity and carcinogenicity have been conducted by the company. As a class, anabolic steroids are considered to be probably carcinogenic to humans (IARC Group 2a).
The use of androgens in different species has resulted in virilisation of the external genitals of female foetuses. Investigations into the genotoxic potential of nandrolone showed it to be positive in an in vitro micronucleus assay and an in vivo micronucleus assay in mouse but not rat, and in the comet assay of mouse and rat. The clinical relevance of these findings is unknown, therefore the risk to patients cannot be ruled out.
