Indications & Clinical Uses

  • Mifegyne (mifepristone) is used in reproductive health for medical termination of pregnancy and early pregnancy loss.
  • Medical termination of intrauterine pregnancy: induces decidual breakdown and detachment of the gestational sac.
  • Management of early pregnancy loss: facilitates expulsion of retained products of conception.
  • Pre‑treatment before misoprostol in combined regimen: sensitizes the uterus to prostaglandins for effective expulsion.

How It Works

  • Mifepristone binds competitively to progesterone receptors in the endometrium, blocking progesterone‑mediated maintenance of the uterine lining. This antagonism leads to decidual breakdown, detachment of the gestational sac, and increased uterine sensitivity to prostaglandins, thereby promoting expulsion of pregnancy tissue when followed by a prostaglandin analogue.

Side Effects

Mifegyne may cause a range of adverse reactions. Monitoring and appropriate medical supervision are recommended.

Common Side Effects

  • Nausea: mild to moderate nausea reported.
  • Vaginal bleeding: increased bleeding during the treatment course.
  • Abdominal cramping: uterine cramping and pain.
  • Fatigue: general feeling of tiredness.
  • Diarrhea: loose stools or increased bowel movements.
  • Headache: occasional mild headache.

Serious or Rare Side Effects

  • Severe hemorrhage: excessive bleeding that may require medical intervention.
  • Infection: signs such as fever, chills, or foul‑smelling discharge.
  • Allergic reaction: rash, itching, swelling, or anaphylaxis in rare cases.

Precautions & Warnings

Before using Mifegyne, certain precautions should be observed.

  • Confirm gestational age: ensure pregnancy is ≤ 9 weeks.
  • Medical supervision: administration must be under a qualified health professional.
  • Contraindications: avoid in chronic adrenal failure, long‑term corticosteroid therapy, or anticoagulant use.
  • Drug interactions: review concomitant medications for potential effects.
  • Follow‑up care: schedule post‑treatment evaluation to assess completeness.
  • Store at ambient temperature: keep below 25 °C, retain original packaging, and protect from moisture.

Avoid Interactions

Mifegyne can interact with other medicines; some require avoidance while others need monitoring.

Major Interactions (Avoid)

  • CYP3A4 inducers (e.g., rifampin): may reduce efficacy.
  • Long‑acting corticosteroids: risk of adrenal insufficiency.
  • Anticoagulants: increased bleeding risk.

Moderate Interactions (Monitor Closely)

  • NSAIDs: may intensify uterine cramping.
  • Macrolide antibiotics: potential modest effect on metabolism.
  • Azole antifungals: may alter plasma levels of mifepristone.

Frequently Asked Questions

Mifegyne, containing the active ingredient mifepristone, is used under medical supervision for the termination of intra‑uterine pregnancy and for the management of early pregnancy loss. It works as part of a regimen that may include a prostaglandin analogue to complete the process.

Mifepristone acts as a progesterone receptor antagonist. By blocking progesterone’s action on the uterine lining, it causes the decidua to break down and the gestational sac to detach, while also making the uterus more responsive to prostaglandins that promote expulsion of pregnancy tissue.

The dose of Mifegyne is determined by the prescribing clinician based on the patient’s clinical situation, gestational age, and local treatment protocols. Only a qualified health professional can set the appropriate regimen, which may involve a single tablet followed by a prostaglandin medication.

Mifegyne is intended for use in early pregnancy to terminate a confirmed intra‑uterine gestation; it is not used to treat ongoing pregnancy. Breastfeeding is generally not recommended until the medication is fully cleared from the body, and patients should discuss any concerns with their health care provider.

To order Mifegyne, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Mifegyne (mifepristone) is the most widely used progesterone receptor antagonist for medical abortion, often combined with misoprostol. Compared with regimens that rely solely on prostaglandins, the mifepristone‑misoprostol combination offers higher efficacy, shorter treatment duration, and a more predictable outcome.

Mifegyne tablets should be stored at ambient temperature, preferably below 25 °C. Keep the product in its original packaging, protect it from moisture and direct sunlight, and store out of reach of children to maintain potency and safety.

Mifegyne is taken orally as a tablet, usually in a single dose under the supervision of a qualified health professional. After ingestion, a prostaglandin analogue such as misoprostol is often prescribed to complete the termination process, following the clinician’s protocol.

Serious risks, though uncommon, include severe hemorrhage requiring medical intervention, infection indicated by fever or foul discharge, and rare allergic reactions such as anaphylaxis. Patients should be monitored closely and instructed to seek immediate medical care if any of these signs occur.

Mifegyne should not be used by individuals with chronic adrenal failure, those on long‑term corticosteroid therapy, patients with known hypersensitivity to mifepristone, or anyone with contraindicated medical conditions such as uncontrolled bleeding disorders. A thorough medical assessment is required before prescribing.
