Posology Adults Generally, treatment is started with 1 tablet Androcur 50 mg twice daily, after the morning and evening meals. The duration of cyproterone acetate treatment should be defined on an individual basis. When a satisfactory result has been achieved, the therapeutic effect should be maintained with the lowest possible dose.
When changing the dose or when discontinuing cyproterone acetate, this should be done gradually. Additional information on special populations Paediatric population Androcur is not recommended for use in male children and adolescents below 18 years of age due to a lack of data on safety and efficacy.
Androcur must not be given before the conclusion of puberty since an unfavourable influence on longitudinal growth and the still unstabilised axes of endocrine function cannot be ruled out. Older people There are no data suggesting the need for a dosage adjustment in elderly patients.

Patients with renal impairment:
The use of Androcur in patients with renal impairment has not been investigated. 2). Method of administration The tablets are to be taken with some liquid after meals. For oral administration.
The most frequently observed adverse drug reactions (ADRs) in patients receiving Androcur are decreased libido, erectile dysfunction and reversible inhibition of spermatogenesis. The most serious ADRs in patients receiving Androcur are hepatic toxicity, benign and malignant liver tumours which may lead to intra-abdominal haemorrhage and thromboembolic events.
The following approximate incidences were estimated from published reports of a number of small clinical trials and spontaneous ADR reports: - very common: incidence ≥ 1:10 - common: incidence < 1:10 but ≥ 1:100 - uncommon: incidence < 1:100 but ≥ 1:1,000 - rare: incidence < 1:1,000 but ≥ 1:10,000 - very rare: incidence < 1:10,000 - not known (cannot be estimated from available data) Neoplasms benign, malignant and unspecified (incl cysts and polyps) Rare: Meningioma.

Immune system disorders Rare:
Hypersensitivity reactions may occur.
Endocrine disorders Not known:
Suppression of adrenocorticol function.
Metabolism and nutrition disorders Common:
Changes in bodyweight during long term treatment (chiefly weight gains in association with fluid retention) Psychiatric disorders Common: Depressive moods and restlessness (temporary). 4). 4).
Hepato-biliary disorders Common:
Direct hepatic toxicity, including jaundice, hepatitis and hepatic failure has been observed in patients treated with Androcur. At dosages of 100 mg and above, cases with fatal outcome have also been reported. Most reported fatal cases were in men with advanced carcinoma of the prostate.
Liver:
Direct hepatic toxicity, including jaundice, hepatitis and hepatic failure, has been observed in patients treated with Androcur. At dosages of 100mg and above, cases with fatal outcome have also been reported. Most reported fatal cases were in men with advanced prostatic cancer.
Toxicity is dose-related and develops, usually, several months after treatment has begun. Liver function tests should be performed pre-treatment, regularly during treatment and whenever any symptoms or signs suggestive of hepatotoxicity occur.
g. metastatic disease, in which case Androcur should be continued only if the perceived benefit outweighs the risk. In very rare cases benign and malignant liver tumours, which may lead to life- threatening intra-abdominal haemorrhage have been observed after the use of Androcur.
If severe upper abdominal complaints, liver enlargement or signs of intra-abdominal haemorrhage occur, a liver tumour should be considered in the differential diagnosis.
Thromboembolic events:
The occurrence of thromboembolic events has been reported patients using Androcur, although a causal relationship has not been established. g. deep vein thrombosis, pulmonary embolism, myocardial infarction), with a history of cerebrovascular accidents or with advanced malignancies are at increased risk of further thromboembolic events, and may be at risk of recurrence of the disease during Androcur therapy.
3.
Meningiomas:
The occurrence of meningiomas (single and multiple) has been reported in association with use of cyproterone acetate primarily at doses of 25 mg and above. 1). High cumulative doses can be reached with prolonged use (several years) or shorter duration with high daily doses.
1 Liver diseases (including Dubin-Johnson syndrome and Rotor syndrome) Malignant tumours (except for carcinoma of the prostate) Previous or existing liver tumours Wasting diseases (because of transient catabolic action) A history of or existing thrombosis or embolism Severe diabetes with vascular changes Sickle cell anaemia Severe chronic depression Meningioma or a history of meningioma.
Androcur should not be given to youths under 18 or to those whose bone maturation and testicular development are incomplete.

Toxicity is dose related and develops, usually, several months after treatment has begun.
Skin and subcutaneous tissue disorders Uncommon:
Rash Not known: Reduction of sebum production leading to dryness of the skin and improvement of existing acne vulgaris has been reported as well as; transient patchy loss and reduced growth of body hair, increased growth of scalp hair, lightening of hair colour and female type of pubic hair growth.
Musculoskeletal and connective tissue disorders Not known:
Osteoporosis (due to long-term androgen deprivation).
Reproductive system disorders Inhibition of spermatogenesis:
Very common: Sperm count and the volume of ejaculate are reduced. Infertility is usual, and there may be azoospermia after 8 weeks. There is usually slight atrophy of the seminiferous tubules. Follow-up examinations have shown these changes to be reversible, spermatogenesis usually reverting to its previous state about 3-5 months after stopping Androcur, or in some users, up to 20 months.
That spermatogenesis can recover even after very long treatment is not yet known. There is evidence that abnormal sperms which might give rise to malformed embryos are produced during treatment with Androcur.
Gynaecomastia:
Common: Gynaecomastia (sometimes combined with tenderness to touch of the mamillae) which usually regresses after withdrawal of the preparation.
Rare:
Galactorrhoea and tender benign nodules have been reported. Symptoms mostly subside after discontinuation of treatment or reduction of dosage.
General disorders and administration site conditions Common:
Hot flushes, sweating, fatigue and lassitude. Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product.

Patients should be monitored for meningiomas in accordance with clinical practice. If a patient treated with Androcur is diagnosed with meningioma, treatment with Androcur and other cyproterone containing products must be permanently stopped (see section ‘Contraindications’).
There is some evidence that the meningioma risk may decrease after treatment discontinuation of cyproterone.
Shortness of breaths:
Shortness of breath may occur under high-dosed treatment with Androcur. This may be due to the stimulatory effect of progesterone and synthetic progestogens on breathing, which is accompanied by hypocapnia and compensatory alkalosis, and which is not considered to require treatment.
3).
Diabetes mellitus:
Strict medical supervision is necessary if the patient suffers from diabetes as Androcur can influence carbohydrate metabolism. Parameters of carbohydrate metabolism should be examined carefully in all diabetics before and regularly during treatment because the requirement for oral antidiabetics or insulin can change.
