Generic Provera (Medroxyprogesterone Acetate)

Introduction

Provera contains the synthetic progestin medroxyprogesterone acetate (MPA) and is supplied as oral tablets in 5 mg and 10 mg strengths. It belongs to the class of progesterone receptor agonists and is used primarily to treat hormone-related gynecologic conditions. In addition to its approved indications, clinicians sometimes employ MPA for certain off-label purposes, although such use is not authorized by the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA). The medication is manufactured by several licensed producers and is marketed in many countries under various brand names.

What is Provera?

Provera is the generic version of well-known medications, containing the active compound medroxyprogesterone acetate. Our online pharmacy provides this generic alternative as a cost-effective treatment option. Medroxyprogesterone acetate is a synthetic analogue of the natural hormone progesterone and has been available worldwide since the s. It is sold under brand names such as Depo-Provera, Depo-SubQ Provera 104, and Prempro (in combination with estrogen). The oral tablet formulation of Provera is produced by multiple reputable manufacturers and is distributed in 5 mg and 10 mg tablets for adult use.

How Provera Works

Medroxyprogesterone acetate binds to intracellular progesterone receptors, forming a hormone-receptor complex that translocates to the nucleus and modulates gene transcription. The resulting effects include:

• Endometrial suppression - the uterine lining becomes thin, reducing the risk of hyperplasia and abnormal bleeding.
• Negative feedback on the hypothalamic-pituitary-gonadal axis - luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion decline, which can inhibit ovulation.
• Anti-androgenic activity - MPA competes with androgens at receptor sites, alleviating androgen-driven symptoms such as acne.

Following oral administration, peak plasma concentrations are reached within 2-4 hours. The drug’s half-life ranges from 12 to 16 hours, allowing once-daily dosing for most indications. Metabolism occurs primarily in the liver via CYP3A4, and metabolites are excreted in the urine.

Conditions Treated with Provera

1. Abnormal Uterine Bleeding (AUB) Provera’s ability to thin the endometrium makes it effective for treating dysfunctional uterine bleeding, especially when caused by anovulatory cycles.

2. Endometriosis By suppressing ovarian hormone production, MPA reduces ectopic endometrial tissue activity, alleviating pelvic pain and dysmenorrhea.

3. Hormone-Replacement Therapy (HRT) for Post-menopausal Women When combined with estrogen, medroxyprogesterone acetate protects the endometrium from estrogen-induced hyperplasia, a standard component of combined HRT regimens.

4. Amenorrhea and Secondary Infertility Related to Luteal Phase Deficiency Supplementation with MPA supports the luteal phase, helping to maintain a suitable endometrial environment for implantation.

Off-Label and Investigational Uses of Provera

• Contraceptive Maintenance in Injectable Formulations - Though the oral tablet is not a contraceptive, clinicians sometimes transition patients from injectable dep­o-provera (MPA) to oral MPA for continuation of progesterone-only contraception. Evidence from small cohort studies suggests comparable cycle control, but formal approval is lacking.

• Management of Certain Cancers - Low-dose MPA has been investigated as an adjunct in hormone-sensitive breast cancer. A 2019 phase II trial reported modest disease-stabilization, yet the regimen remains experimental and is not FDA-approved for oncology.

• Adjunctive Therapy for Severe Menstrual-Related Mood Disorders - Some psychiatrists prescribe MPA off-label to mitigate menstrual-related mood swings, based on its stabilizing effect on hormonal fluctuations. Controlled data are limited, and usage should occur only under specialist supervision.

All off-label applications are not endorsed by regulatory agencies. Patients should discuss any such consideration with a qualified healthcare professional before initiating treatment.

Is Provera the Right Medication for You?

Provera is appropriate for adult women who require progesterone supplementation for the approved conditions listed above. It is particularly useful when:

• A thin endometrium is needed to prevent hyperplasia.
• Ovulation suppression is desired without estrogen exposure.
• A cost-effective oral progestin is preferred over injectable forms.

Contraindications include:

• Known hypersensitivity to medroxyprogesterone acetate or any tablet excipient.
• Active or history of thromboembolic disease, uncontrolled hypertension, or severe liver dysfunction.
• Pregnancy - MPA may affect fetal development and is not recommended for use in pregnant individuals.

Patients with a history of mood disorders, breast cancer, or unexplained uterine bleeding should receive a thorough medical evaluation before starting Provera.

Risks, Side Effects, and Interactions

Common

• Headache
• Nausea or mild gastrointestinal upset
• Breast tenderness or enlargement
• Mood changes (e.g., irritability, mild depression)
• Weight gain or fluid retention

Rare

• Decreased bone mineral density with long-term use (> 12 months)
• Hyperglycemia or worsening of diabetes control
• Elevated serum cholesterol or triglycerides

Serious

• Deep-vein thrombosis or pulmonary embolism
• Severe hepatic impairment (jaundice, hepatic encephalopathy)
• Allergic reactions: rash, pruritus, angioedema, anaphylaxis
• Endometrial cancer: prolonged unopposed estrogen without adequate progestin protection

Drug-Drug Interactions

• CYP3A4 inducers (e.g., rifampin, carbamazepine, St. John’s Wort) may lower MPA plasma levels, reducing efficacy.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, grapefruit juice) can increase MPA concentrations, potentially heightening side-effect risk.
• Anticoagulants (warfarin) may have altered effect; monitoring of INR is advisable.

Drug-Food Interactions

• High-fat meals do not significantly affect absorption, but patients should maintain consistent intake patterns to avoid variability.
• Alcohol in excess can exacerbate liver metabolism disturbances; moderation is recommended.

Use: Dosing, Missed Dose, Overdose

Standard Dosing

• Endometrial protection (HRT): 5 mg once daily.
• Abnormal uterine bleeding: 10 mg once daily for 5-10 days, repeated as directed.
• Endometriosis: 10 mg daily, often in a cyclic regimen (e.g., 21 days on, 7 days off).

Doses may be adjusted by a healthcare professional based on response and tolerance.

Missed Dose If a dose is missed within 12 hours, take it as soon as remembered. If more than 12 hours have passed, skip the missed tablet and resume the regular schedule. Do not double-dose.

Overdose Acute overdose is uncommon but may present with pronounced nausea, vomiting, dizziness, or severe hypotension. Immediate medical evaluation is warranted. Supportive care, gastric decontamination, and monitoring of vital signs are the primary interventions.

Practical Precautions

• Tablets may be taken with or without food.
• Avoid concomitant use of strong CYP3A4 modulators without professional guidance.
• Operating heavy machinery is generally safe, but patients experiencing dizziness or severe fatigue should exercise caution.

FAQ

• Can I travel internationally with Provera tablets?

  • Yes. The tablets are stable at normal room temperature and can be packed in the original container. Carry a copy of the prescription or a physician’s letter if required by customs.

• Does Provera interact with caffeine or nicotine?

  • No direct pharmacokinetic interaction has been documented. However, both caffeine and nicotine can exacerbate menstrual-related symptoms, so moderation may improve overall comfort.

• What do the Provera tablets look like?

  • The 5 mg tablets are typically round, white, and imprinted with “5 MPA.” The 10 mg tablets are round, white or off-white, marked with “10 MPA.” Inactive ingredients may include lactose, maize starch, and magnesium stearate.

• Is Provera safe for people with a history of migraines?

  • Migraine sufferers should discuss use with a clinician because hormonal fluctuations, including progestin therapy, can trigger attacks in some individuals.

• How should Provera be stored in hot climates?

  • Keep tablets in a cool, dry place away from direct sunlight. If ambient temperature exceeds 30 °C (86 °F) for prolonged periods, store the bottle in an insulated container or a refrigerator (do not freeze).

• Can Provera affect hormone-based drug testing?

  • Standard drug screens do not test for progestins. However, specialized endocrine panels might detect elevated progesterone levels, which could be noted in the results.

• Are there any vegan-friendly versions of Provera?

  • Most formulations contain lactose derived from dairy, making them unsuitable for strict vegans. Some manufacturers offer lactose-free tablets; verify the excipient list before purchase.

• What is the difference between Provera and Depo-Provera?

  • Provera is an oral tablet taken daily, whereas Depo-Provera is a long-acting injectable given every 12-14 weeks. Both contain medroxyprogesterone acetate but differ in route, dosing frequency, and pharmacokinetic profile.

• Is it necessary to have blood work while on Provera?

  • Baseline liver function tests and lipid panels are advisable before initiating therapy, especially for long-term use. Periodic monitoring (e.g., annually) helps detect any metabolic changes early.

• Can I take Provera while on hormonal birth control pills?

  • Concurrent use may lead to excessive progestin exposure and increase side-effect risk. Coordination with a healthcare provider is recommended to adjust dosing or select an alternative regimen.
