Mifegyne

Mifepristone, the active ingredient in Mifegyne, is a progesterone receptor antagonist presented as a tablet for oral use. It is used for medical termination of early pregnancy and related obstetric indications.

GNH USA supplies Mifegyne as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Mifegyne, a progesterone receptor antagonist, is employed in several obstetric contexts.

- Medical termination of early pregnancy: induces decidual breakdown and facilitates expulsion of the gestational sac. - Management of miscarriage: promotes uterine evacuation when a miscarriage is incomplete. - Cervical ripening prior to surgical abortion: softens the cervix to allow safer surgical procedures.

Mifegyne may cause a range of adverse reactions, which are grouped by frequency.

Common Side Effects: - Abdominal pain: cramping or discomfort in the lower abdomen. - Vaginal bleeding: spotting or heavier bleeding than a typical period. - Nausea: feeling of queasiness or urge to vomit. - Diarrhea: loose or watery stools. - Headache: mild to moderate head pain. - Fatigue: feeling unusually tired.

Serious or Rare Side Effects: - Severe infection: signs of sepsis or pelvic infection. - Heavy bleeding: excessive hemorrhage requiring medical attention. - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Liver dysfunction: jaundice or abnormal liver tests. - Uterine rupture: rare but life‑threatening tearing of the uterus.

When using Mifegyne, several safety considerations are essential.

- Confirm gestational age: ensure pregnancy is within the approved timeframe for medical termination. - Evaluate contraindications: exclude patients with chronic adrenal failure, long‑term corticosteroid therapy, or severe anemia. - Assess for ectopic pregnancy: rule out non‑intrauterine implantation before administration. - Review concomitant medications: consider potential drug interactions that may affect efficacy. - Monitor for adverse reactions: observe patients for signs of heavy bleeding or infection. - Store at room temperature: keep in the original pack, protect from moisture.

Mifegyne can interact with other medicines, requiring attention to the level of risk.

Major Interactions (Avoid): - Rifampin: strong CYP3A4 inducer that may reduce mifepristone effectiveness. - St. John’s wort: herbal CYP3A4 inducer potentially lowering drug levels. - Antifungal azoles (e.g., ketoconazole): may increase mifepristone exposure and risk of toxicity.

Moderate Interactions (Monitor Closely): - Warfarin or other anticoagulants: may enhance bleeding risk. - NSAIDs: can increase gastrointestinal irritation and bleeding. - SSRIs (selective serotonin reuptake inhibitors): may modestly affect hemostasis.
