Medical examination:

Physicians should consider monitoring patients receiving Labdec 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 - Labdec can improve glucose tolerance in diabetic patients.

- Anti-coagulant therapy - Labdec 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 Labdec 50mg/ml should only be used if the benefits outweigh the risks.

Adverse events:

If anabolic steroid-associated adverse reactions occur , treatment with Labdec 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:

Labdec 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 Labdec.

Labdec 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 Labdec in high dosages may accelerate epiphyseal closure and sexual maturation.

Due to the nature of Labdec, side effects cannot be quickly reversed by discontinuing medication. Injectables in general, may cause local reaction at the injection site.

Labdec at the recommended dosages is unlikely to produce virilising effects. High dosages, prolonged treatment and/or too frequent administration may cause:

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 Labdec 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.

Pharmacokinetic properties

The information provided in Pharmacokinetic properties of Labdec is based on data of another medicine with exactly the same composition as the Labdec of the medicine (Nandrolone). Be careful and be sure to specify the information on the section Pharmacokinetic properties in the instructions to the drug Labdec directly from the package or from the pharmacist at the pharmacy.

Absorption

Nandrolone decanoate 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 nandrolone decanoate 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.

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.

Incompatibilities
