2.

This medicine contains medroxyprogesterone acetate, which is one of a group of medicines called 'Progestogens'. Progestogens act like progesterone, a natural sex hormone. Medroxyprogesterone acetate can slow down the growth of certain tumours which are sensitive to hormones. Provera tablets are used in the treatment of cancer in the breast, kidney (in men and women) and in the lining of the womb (endometrial cancer). It is also used to treat cancer which has spread to other parts of the body (metastatic cancer) in post-menopausal women (women who have stopped having their periods). It is not expected that Provera Tablets will be used in children for the above indications. If you are not certain why you are being given this medicine, ask your doctor. You must talk to a doctor if you do not feel better or if you feel worse.

What you need to know before you take it

e Provera Tablets

Do not take Provera Tablets:

  • If you are hypersensitive (allergic) to medroxyprogesterone acetate or other similar hormone medicines or any of the other ingredients of this medicine (listed in section 6).
  • If you have liver problems
  • If you have a heart condition where you feel pain in your chest when you exert yourself (angina) or have had a heart attack or if you have been told that you are at risk of developing cardiovascular diseases
  • If you have raised levels of calcium in the blood (hypercalcaemia) associated with metastasised bone cancer
  • If you have suspected or recently diagnosed breast cancer for the first time

If you have undiagnosed vaginal bleeding If you have past or recent blood clot disorders, including deep vein thrombosis (DVT), pulmonary embolism (clot(s) in the lung), thrombophlebitis (inflammation of the blood vessels) or if you have been told that you are at risk of developing these conditions If you have a history of a condition known as porphyria (a hereditary blood disorder) If you have a missed abortion (where the woman's body does not expel the dead foetus), miscarriage or pregnancy.

Warnings and precautions Talk to your doctor or pharmacist if you have or have ever had any of the following conditions to help him or her decide if Provera Tablets are suitable for you:

  • fluid retention
  • diseases that affect the heart and blood vessels (cardiovascular disease)
  • epilepsy
  • migraine headaches
  • sudden vision disturbance
  • asthma
  • liver or kidney problems
  • diabetes
  • a meningioma (a usually benign tumour that forms in the layers of tissue that cover your brain and spinal cord)
  • depression or a history of depression
  • hyperlipidaemia (raised levels of fat in the blood)
  • if you are taking or have recently taken any other medicines, even those not prescribed
  • jaundice (a condition which causes the skin or whites of the eye to appear yellow)
  • a significant increase in high blood pressure
  • hormonal imbalance Treatment with Provera Tablets may cause you to have symptoms associated with Cushing's syndrome. Meningioma Use of medroxyprogesterone acetate has been linked to the development of a usually benign tumour of the tissue surrounding the brain and spinal cord (meningioma). The risk increases especially when you use it for longer duration (several years). If you are diagnosed with meningioma, your doctor will reconsider your treatment with Provera Tablets. If you notice any symptoms such as changes in vision (e.g. seeing double or blurriness), hearing loss or ringing in the ears, loss of smell, headaches that worsen with time, memory loss, seizures, weakness in your arms or legs, you must tell your doctor straightaway. Risk of Venous Thromboembolism (VTE) All women have a small chance of having a blood clot in the veins of the leg, in the lung or other parts of the body. The chances of getting a clot are very slightly increased if you are taking a hormone medicine like Provera Tablets. You are more likely to get a clot whether or not you are taking Provera Tablets if you:
  • are very overweight
  • have relatives who have had blood clots
  • have had a blood clot in the veins or lungs before
  • are unable to move for long periods of time (for example after an operation)
  • have a serious injury or have major surgery
  • have a history of repeated miscarriage (See section 4 on 'Possible side effects' for more information on the warning signs of blood clots).

  • anti-infective medicines like rifampicin, rifabutin, efavirenz or nevirapine for infections caused by bacteria and yeast
  • ritonavir and nelfinavir, sometimes used to treat HIV and AIDS
  • cytotoxic drugs (drugs that kill cancerous cells)
  • ciclosporin for suppressing the immune system
  • herbal preparations containing St. John's wort
  • aminoglutethimide sometimes used in Cushing's syndrome
  • anticoagulants like warfarin for thinning the blood
  • pain killers like aspirin, ibuprofen or naproxen and vasodilators like hydralazine, minoxidil may affect the way Provera Tablets work. Pregnancy If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Avoid becoming pregnant while being treated with Provera Tablets. This medicine must not be taken if you are pregnant as hormonal medicines may affect the developing baby.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Progestogen indicated for the treatment of certain hormone dependant neoplasms, such as:

1. Endometrial carcinoma.

2. Renal cell carcinoma.

3. Carcinoma of breast in post menopausal women.

4.2. Posology and method of administration

Posology

Adults

Endometrial and renal cell carcinoma

200 - 600 mg daily

Breast carcinoma

400 - 1500 mg daily

The incidence of minor side-effects, such as indigestion and weight gain, increases with the increase in dose.

Response to hormonal therapy may not be evident until after at least 8-10 weeks of therapy.

Elderly patients: This product has been used primarily in the older age group for the treatment of malignancies. There is no evidence to suggest that the older age group is any less prepared to handle the drug metabolically than is the younger patient. Therefore, the same dosage, contraindications, and precautions would apply to either age group.

Paediatric population: The product is not anticipated for paediatric use in the indications recommended.

Method of administration

For Oral use.

4.3. Contraindications

Medroxyprogesterone acetate is contraindicated in the following conditions:

• thrombophlebitis, thromboembolic disorders, and where there is a high risk of developing such manifestations [presence or history of atrial fibrillation, valvular disorders, endocarditis, heart failure, pulmonary embolism; thromboembolic ischaemic attack (TIA), cerebral infarction; atherosclerosis; immediate post surgery period]

• hypercalcaemia in patients with osseous metastases

• hypersensitivity to the active substance or to any of the excipients listed in section 6.1

• impaired liver function or active liver disease

• missed abortion, metrorrhagia, known or suspected pregnancy

• undiagnosed vaginal bleeding

• previous idiopathic or current venous thromboembolism (deep vein thrombosis, pulmonary embolism)

• active or recent arterial thromboembolic disease (e.g. angina, myocardial infarction)

• suspected or early breast carcinoma

Progestogens are known to be porphyrogenic. Patients with a history of attacks or aged under 30 are at greatest risk of an acute attack while on progesterone treatment. A careful assessment of potential benefit should be made where this risk is present.

4.4. Special warnings and precautions for use

Warnings:

In the treatment of carcinoma of breast occasional cases of hypercalcaemia have been reported.

Unexpected vaginal bleeding during therapy with medroxyprogesterone acetate should be investigated.

Medication should not be readministered pending examination if there is sudden, partial or complete loss of vision or if there is a sudden, onset of proptosis, diplopia or migraine. If examination reveals papilloedema or retinal vascular lesions, medication should not be readministered.

Medroxyprogesterone acetate may produce Cushingoid symptoms.

Some patients receiving medroxyprogesterone acetate may exhibit suppressed adrenal function. Medroxyprogesterone acetate may decrease ACTH and hydrocortisone blood levels.

Treatment with medroxyprogesterone acetate should be discontinued in the event of:

• jaundice or deterioration in liver function

• significant increase in blood pressure

• new onset of migraine-type headache

Meningioma

Cases of meningioma (single and multiple) have been reported in patients treated with medroxyprogesterone acetate for a prolonged time (several years). If a patient is diagnosed with meningioma, the need for further treatment with medroxyprogesterone acetate should be carefully considered on a case-by-case basis taking into account individual benefits and risks. In some cases, shrinkage of meningioma was observed after treatment discontinuation of depot medroxyprogesterone acetate.

Caution is advised when recommending medroxyprogesterone acetate to patients with a history of meningioma.

Precautions:

Animal studies show that medroxyprogesterone acetate possesses adrenocorticoid activity. This has also been reported in man, therefore patients receiving large doses continuously and for long periods should be observed closely for signs normally associated with adrenocorticoid therapy, such as hypertension, sodium retention, oedema, etc. Care is needed in treating patients with diabetes and/or arterial hypertension.

Before using medroxyprogesterone acetate, the general medical condition of the patient should be carefully evaluated.

This product should be used under the supervision of a specialist and the patient kept under regular surveillance.

Patients with the following conditions should be carefully monitored while taking progestogens:

• Conditions which may be influenced by potential fluid retention

o

Epilepsy

o

Migraine

o

Asthma

o

Cardiac dysfunction

o

Renal dysfunction

• History of mental depression

• Diabetes (a decrease in glucose tolerance has been observed in some patients).

• Hyperlipidaemia

The pathologist (laboratory) should be informed of the patient's use of medroxyprogesterone acetate if endometrial or endocervical tissue is submitted for examination.

The physician/laboratory should be informed that medroxyprogesterone acetate may decrease the levels of the following endocrine biomarkers:

• Plasma/urinary steroids (e.g. cortisol, oestrogen, pregnanediol, progesterone, testosterone)

• Plasma/urinary gonadotrophins (e.g. LH and FSH)

• Sex-hormone-binding-globulin

The use of medroxyprogesterone acetate in oncology indications may also cause partial adrenal insufficiency (decrease in pituitary-adrenal axis response) during Metyrapone testing. Thus, the ability of adrenal cortex to respond to ACTH should be demonstrated before metyrapone is administered.

Although medroxyprogesterone acetate has not been causally associated with the induction of thromboembolic disorders, any patient with a history or who develops this kind of event while undergoing therapy with medroxyprogesterone acetate should have her status and need for treatment carefully assessed before continuing therapy.

Risk of venous thromboembolism (VTE)

The risk of VTE has not been assessed for progesterone alone. However, VTE is a known risk factor of oestrogen-only and combined hormone replacement therapy. When prescribing medroxyprogesterone acetate for oncology indications, the following precautions and risk factors should be considered in the light of the patient's condition, the dose of medroxyprogesterone acetate and the duration of therapy:

• Generally recognised risk factors for VTE include a personal or family history of VTE or known thromboembolic states, severe obesity (BMI > 30 kg/m2) and systemic lupus erythematosus.

• The risk of VTE may be temporarily increased with prolonged immobilisation, major trauma or major surgery.

• If VTE develops after initiating therapy, medroxyprogesterone acetate should be discontinued. Patients should be told to contact their doctor immediately if they become aware of a symptom suggestive of potential thromboembolism (e.g. painful swelling of a leg, sudden pain in the chest, dyspnoea).

Excipient Information

Each 100 mg tablet contains 0.139 mg sodium benzoate (see section 2). Benzoates may increase unconjugated bilirubin levels by displacing bilirubin from albumin, which may increase neonatal jaundice. Neonatal hyperbilirubinaemia may lead to kernicterus (non-conjugated bilirubin deposits in the brain tissue) and encephalopathy. However, this medicinal product is not indicated for use in children and this warning is only included for completeness.

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium free'.

4.5. Interaction with other medicinal products and other forms of interaction

Interaction with other medicinal products

The metabolism of progestogens may be increased by concomitant administration of compounds known to induce drug-metabolising enzymes, specifically cytochrome P450 enzymes. These compounds include anticonvulsants (e.g. phenobarbital, phenytoin, carbamazepine) and anti-infectives (e.g. rifampicin, rifabutin, nevirapine, efavirenz,).

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. Progestogen levels may therefore be reduced.

Aminoglutethimide has been reported to decrease plasma levels of some progestogens.

Concurrent administration of ciclosporin and MPA has been reported to lead to increased plasma ciclosporin levels and/or decreased plasma MPA levels.

Interactions with oral anti-coagulants have been reported rarely, but causality has not been established.

When used in combination with cytotoxic drugs, it is possible that progestogens may reduce the haematological toxicity of chemotherapy.

Special care should be taken when progestogens are administered with other drugs which also cause fluid retention, such as NSAIDs and vasodilators.

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.

Other forms of interaction

Progestogens can influence certain laboratory tests (e.g. tests for hepatic function, thyroid function and coagulation).

4.6. Fertility, pregnancy and lactation

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/or 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.

4.7. Effects on ability to drive and use machines

No adverse effect has been reported.

4.8. Undesirable effects

The table below provides a listing of adverse drug reactions with frequency based on all-causality data from 1337 patients who received MPA in 4 pivotal studies that evaluated efficacy and safety of MPA for oncology indications.

The following lists of adverse reactions are listed within the organ system classes, under headings of frequency (number of patients expected to experience the reaction), using the following categories:
