Progestogen. Indicated for dysfunctional (anovulatory) uterine bleeding, secondary amenorrhoea and for mild to moderate endometriosis.
Posology
Adults:
Dysfunctional (anovulatory) uterine bleeding: 2.5 - 10 mg daily for 5 - 10 days commencing on the assumed or calculated 16th - 21st day of the cycle. Treatment should be given for two consecutive cycles. When bleeding occurs from a poorly developed proliferative endometrium, conventional oestrogen therapy may be employed in conjunction with medroxyprogesterone acetate in doses of 5 - 10 mg for 10 days.
Secondary amenorrhoea: 2.5 - 10 mg daily for 5 - 10 days beginning on the assumed or calculated 16th to 21st day of the cycle. Repeat the treatment for three consecutive cycles. In amenorrhoea associated with a poorly developed proliferative endometrium, conventional oestrogen therapy may be employed in conjunction with medroxyprogesterone acetate in doses of 5 - 10 mg for 10 days.
Mild to moderate endometriosis: Beginning on the first day of the menstrual cycle, 10 mg three times a day for 90 consecutive days. Breakthrough bleeding, which is self-limiting, may occur. No additional hormonal therapy is recommended for the management of this bleeding.
Elderly: Not applicable
Paediatric population: Not applicable
Method of administration
For oral use.
Known or suspected pregnancy;
Known, past or suspected breast cancer
Previous idiopathic or current venous thromboembolism (deep venous thrombosis, pulmonary embolism)
Active or recent arterial thromboembolic disease (e.g. angina, myocardial infarction)
Acute liver disease or a history of liver disease as long as liver function tests have failed to return to normal
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1
Porphyria
Medical Examination/Follow-Up
Before initiating or reinstituting therapy, a complete personal and family medical history should be taken. Physical (including pelvic) examination should be guided by this and by the contraindications (section 4.3) and warnings (section 4.4) for use. During treatment, periodic check-ups are recommended of a frequency and nature adapted to the individual woman, but may include, if judged appropriate by the clinician, abdominal and pelvic examination. Women should be encouraged to participate in the national breast cancer screening programme (mammography) and the national cervical screening programme (cervical cytology) as appropriate for their age.
The possibility of genital tract pathology should be considered before commencing treatment in women with abnormal uterine bleeding, especially in women over 45, who may require gynaecological investigation.
A negative pregnancy test should be demonstrated before starting therapy (see section 4.6).
Doses of up to 30 mg a day may not suppress ovulation and patients should be advised to take adequate contraceptive measures, where appropriate.
Conditions which need Supervision
If any of the following conditions are present, have occurred previously, and/or have been aggravated during pregnancy or previous hormone treatment, the patient should be closely supervised. It should be taken into account that these conditions may recur or be aggravated during treatment with medroxyprogesterone acetate, in particular:
- A history of, or risk factors for, thromboembolic disorders (see below)
- Risk factors for oestrogen dependent tumours, e.g. 1 degree heredity for breast cancer
- Hypertension
- Liver disorders (e.g. liver adenoma)
- Diabetes mellitus with or without vascular involvement
- Cholelithiasis
- Migraine or (severe) headache
- Systemic lupus erythematosus.
- Epilepsy
- Asthma
- Otosclerosis
Meningiomas have been reported following long term administration of progestogens, including medroxyprogesterone acetate. This medicine should be discontinued if a meningioma is diagnosed. Caution is advised when recommending medroxyprogesterone acetate to patients with a history of meningioma.
Rare cases of thrombo-embolism have been reported with use of medroxyprogesterone acetate, especially at higher doses. Causality has not been established.
History or emergence of the following conditions requires careful consideration and appropriate investigation: signs of a blood clot; migraine or unusually severe headaches or acute visual disturbances of any kind.
Medroxyprogesterone acetate, especially in high doses, may cause weight gain and fluid retention. With this in mind, caution should be exercised in treating any patient with a pre-existing medical condition, such as epilepsy, migraine, asthma, cardiac or renal dysfunction, that might be adversely affected by weight gain or fluid retention.
Some patients receiving medroxyprogesterone acetate may exhibit a decreased glucose tolerance. The mechanism for this is not known. This fact should be borne in mind when treating all patients and especially known diabetics.
This product contains lactose and sucrose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
Patients with a history of treatment for mental depression should be carefully monitored while receiving medroxyprogesterone acetate therapy. Some patients may complain of premenstrual like depression while on medroxyprogesterone acetate therapy.
Reasons for Immediate Withdrawal of Therapy:
Therapy should be discontinued in case a contraindication is discovered and in the following situations:
- Jaundice or deterioration in liver function
- Significant increase in blood pressure
- New onset of migraine-type headache
Aminoglutethimide administered concurrently with medroxyprogesterone acetate may significantly depress the bioavailability of medroxyprogesterone acetate.
Interactions with other medicinal treatments (including oral anti-coagulants) have rarely been reported, but causality has not been determined. The possibility of interaction should be borne in mind in patients receiving concurrent treatment with other drugs.
The metabolism of progestogens may be increased by concomitant use of substances known to induce drug-metabolising enzymes, specifically cytochrome P450 enzymes, such as anticonvulsants (e.g. phenobarbital, phenytoin, carbamazepine) and anti-infectives (e.g. rifampicin, rifabutin, nevirapine, efavirenz).
Medroxyprogesterone acetate (MPA) is metabolized in-vitro primarily by hydroxylation via the CYP3A4. Specific drug-drug interaction studies evaluating the clinical effects with CYP3A4 inducers or inhibitors on MPA have not been conducted and therefore the clinical effects of CYP3A4 inducers or inhibitors are unknown.
Ritonavir and nelfinavir, although known as strong inhibitors, by contrast exhibit inducing properties when used concomitantly with steroid hormones. Herbal preparations containing St John's wort (Hypericum perforatum) may induce the metabolism of progestogens.
Clinically, an increased metabolism of progestogens may lead to decreased effect.
Fertility
MPA at oral doses may inhibit ovulation.
Women may experience a delay in return to fertility (conception) following discontinuation of this medicine.
Pregnancy
Medroxyprogesterone acetate is contraindicated in women who are pregnant.
Some reports suggest an association between intrauterine exposure to progestational drugs in the first trimester of pregnancy and genital abnormalities in male and female foetuses.
If medroxyprogesterone acetate is used during pregnancy, or if the patient becomes pregnant while using this drug, the patient should be apprised of the potential hazard to the foetus.
Infants from unintentional pregnancies that occur 1 to 2 months after injection of medroxyprogesterone acetate injectable suspension may be at an increased risk of low birth weight, which, in turn, is associated with an increased risk of neonatal death. The attributable risk is low because pregnancies while on medroxyprogesterone acetate are uncommon.
Breast-feeding
Medroxyprogesterone acetate and its metabolites are secreted in breast milk.
In nursing mothers treated with medroxyprogesterone acetate injection 150 mg IM every 3 months, milk composition, quality, and amount are not adversely affected
Neonates and infants exposed to MPA from breast milk have been studied for developmental and behavioural effects through puberty. No adverse effects have been noted.
However, due to limitations of the data regarding the effects of MPA in breastfed infants less than six weeks old, medroxyprogesterone acetate should be given no sooner than six weeks post-partum when the infant's enzyme system is more developed.
No adverse effect has been reported.
The table below provides a listing of adverse drug reactions with frequency based on all-causality data from Phase 3 clinical studies that evaluated efficacy and safety of DMPA in gynaecology.
