Generic Provera

Introduction

Provera is a prescription medication used primarily in women's health to supplement or replace natural progesterone. The active compound, medroxyprogesterone acetate, is a synthetic progestogen that influences the hormonal cycle and the uterine lining. In the United Kingdom, Provera is prescribed for a range of conditions, including abnormal uterine bleeding, secondary amenorrhoea, and as part of hormone replacement therapy (HRT). It may also be employed off‑label for endometriosis and certain infertility protocols. The product is manufactured by several licensed pharmaceutical companies that meet the standards of the Medicines and Healthcare products Regulatory Agency (MHRA).

What is Provera?

Provera is a tablet formulation containing 10 mg of medroxyprogesterone acetate. It belongs to the class of synthetic progestogens, which are analogues of the naturally occurring hormone progesterone. The drug was first developed in the 196s and has been marketed in the UK under the trade name Provera for several decades. Multiple manufacturers produce the same active ingredient; all products are required to demonstrate bio‑equivalence to the reference standard before receiving an MHRA licence.

How Provera Works

Medroxyprogesterone acetate binds to progesterone receptors in the endometrium, cervix, and breast tissue. By activating these receptors, it mimics the actions of endogenous progesterone:

• Endometrial stabilization – it converts a proliferative endometrium (driven by estrogen) into a secretory state, reducing the risk of irregular shedding and heavy bleeding.
• Ovulation suppression – at higher doses, the drug provides negative feedback to the hypothalamic‑pituitary‑ovarian axis, lowering luteinising hormone (LH) and follicle‑stimulating hormone (FSH) secretion.
• Hormonal priming – in HRT regimens, it counteracts estrogen‑induced endometrial hyperplasia, protecting against abnormal bleeding and long‑term malignant change.

After oral ingestion, medroxyprogesterone acetate is rapidly absorbed, reaching peak plasma concentrations within 2–3 hours. The compound is metabolised primarily by hepatic cytochrome P450 enzymes (CYP3A4) and eliminated in the urine and feces with an approximate half‑life of 12–18 hours, allowing once‑daily dosing in most indications.

Conditions Treated with Provera

• Abnormal uterine bleeding (AUB) – Provera induces regular shedding of the endometrium, useful when bleeding is caused by hormonal imbalance rather than structural pathology.
• Secondary amenorrhoea – In women who have stopped menstruating due to low progesterone output, Provera can re‑establish a withdrawal bleed.
• Hormone replacement therapy (HRT) – Combined with oestrogen, it protects the uterine lining in post‑menopausal women receiving systemic estrogen.
• Endometriosis – By suppressing ovulation and reducing ectopic endometrial growth, Provera alleviates pelvic pain in some patients (off‑label).
• Infertility protocols – Used in luteal‑phase support during assisted reproductive technologies to promote implantation (off‑label).

Data from the UK National Health Service (NHS) indicate that abnormal uterine bleeding affects up to 30 % of women of reproductive age, making Provera a frequently prescribed option in gynecological practice.

Who is Provera For?

Provera is appropriate for adult women who require progestogenic therapy for any of the indications listed above. Typical candidates include:

• Women of reproductive age with clinically confirmed progesterone deficiency causing irregular or absent periods.
• Perimenopausal or post‑menopausal patients receiving estrogen‑only HRT who need endometrial protection.
• Patients with confirmed benign uterine bleeding where structural causes (fibroids, polyps) have been excluded.
• Individuals undergoing fertility treatment who require luteal‑phase support.

Provera is not recommended for:

• Women who are pregnant or intend to become pregnant without medical supervision.
• Patients with a history of venous thromboembolism, severe liver disease, or undiagnosed vaginal bleeding.
• Those with known hypersensitivity to medroxyprogesterone acetate or any tablet excipients.

A thorough clinical assessment, including blood tests and imaging where appropriate, should precede initiation.

Risks, Side Effects, and Interactions

Common

• Nausea or mild gastrointestinal upset.
• Headache or dizziness.
• Breast tenderness or oedema.
• Weight gain or fluid retention.

Rare

• Mood changes, including depressive symptoms.
• Decreased libido.
• Skin reactions such as rash or pruritus.

Serious

• Thromboembolic events – deep‑vein thrombosis, pulmonary embolism, particularly in smokers or those with clotting disorders.
• Liver dysfunction – jaundice, elevated transaminases, hepatitis‑like syndrome.
• Severe allergic reaction – anaphylaxis, angio‑oedema.

Drug–Drug Interactions

• CYP3A4 inducers (e.g., rifampicin, carbamazepine) may reduce plasma concentrations, decreasing efficacy.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) can increase exposure, raising the risk of side effects.
• Anticoagulants – progestogens may augment the pro‑coagulant effect of warfarin or direct oral anticoagulants, requiring closer INR monitoring.
• Anticonvulsants – enzyme‑inducing agents may lower hormone levels, potentially compromising therapeutic goals.

Patients should always disclose all current medications, including over‑the‑counter products and herbal supplements.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – For abnormal uterine bleeding, the usual regimen is 10 mg taken orally once daily for 10–14 days, followed by a withdrawal bleed. In HRT, a typical dose is 10 mg daily, taken continuously. Dose adjustments are clinician‑determined based on response and tolerability.
• Missed dose – If a dose is forgotten within 12 hours, take it as soon as remembered. If more than 12 hours have elapsed, skip the missed dose and continue with the regular schedule; do not double‑dose.
• Overdose – Symptoms may include severe nausea, vomiting, or dizziness. In the event of suspected overdose, seek immediate medical attention; supportive care is the mainstay of treatment.
• Administration advice – Tablets may be taken with or without food. Alcohol does not markedly affect absorption but can exacerbate hepatic side effects; moderate consumption is advised.
• Renal or hepatic impairment – No dosage reduction is routinely required, but patients with severe liver disease should be monitored closely.

FAQ

• Is Provera available in both brand‑name and generic forms in the UK?
  Yes. The brand name Provera contains medroxyprogesterone acetate, and there are generic tablets with the same strength and formulation that are typically less expensive.

• Does Provera require refrigeration?
  No. tablets should be stored at controlled room temperature, away from moisture and direct sunlight.

• What does the Provera tablet look like?
  In the UK, the 10 mg tablet is usually round, white to off‑white, and may be scored for division. In some regions the tablet is oval; inactive ingredients can differ slightly between manufacturers.

• Can I travel internationally with Provera tablets?
  Yes, provided you keep the medication in its original packaging with a copy of the prescription or a doctor’s letter, as some countries require documentation for hormonal drugs.

• Are there differences in formulation between EU and US versions of medroxyprogesterone acetate?
  The active ingredient is identical, but excipients such as lactose, cellulose, or magnesium stearate may vary. These differences rarely affect efficacy but could be relevant for patients with specific allergies.

• How long can I keep an unopened pack of Provera?
  The shelf‑life is typically three years from the date of manufacture, as indicated on the blister pack. Check the expiry date before use.

• Will Provera appear on drug‑testing panels for employment or sport?
  Medroxyprogesterone acetate is not a prohibited substance in standard occupational drug screens, but some sports agencies list it under prohibited hormones; athletes should verify current regulations.

• Is Provera safe for women with a history of breast cancer?
  Progestogens can influence hormonal pathways; clinicians usually avoid prescribing progestogenic therapy to patients with estrogen‑ or progesterone‑sensitive breast cancer unless the benefits clearly outweigh the risks.

• Can Provera be taken with hormonal contraceptive patches?
  Combining Provera with estrogen‑containing contraceptives may increase the risk of endometrial hyperplasia. It is generally unnecessary to add a progestogen when an effective combined contraceptive method is used.

• What are the environmental considerations for disposing of unused Provera tablets?
  Unused tablets should be returned to a pharmacy take‑back programme or disposed of according to local hazardous waste guidelines; flushing them down the toilet can contribute to water‑way contamination.
