Indications & Clinical Uses

Microgynon 50, a combined oral contraceptive, is used to manage reproductive health by influencing hormonal pathways.

  • Prevention of pregnancy: provides reliable contraceptive protection for women of childbearing age.
  • Regulation of menstrual cycles: helps achieve more predictable cycle length and flow.

How It Works

  • Ethinylestradiol and levonorgestrel bind to estrogen and progesterone receptors, respectively, suppressing the hypothalamic‑pituitary‑gonadal axis, preventing the LH surge and follicular development, while also thickening cervical mucus and inducing endometrial changes that together inhibit ovulation and implantation.

Side Effects

Microgynon 50 may cause a range of adverse reactions.

Common Side Effects

  • Nausea: mild to moderate stomach upset.
  • Headache: tension‑type or migraine‑like pain.
  • Breast tenderness: temporary swelling or soreness.
  • Spotting between periods: light vaginal bleeding.

Serious or Rare Side Effects

  • Deep vein thrombosis: blood clot formation in deep veins.
  • Pulmonary embolism: clot traveling to the lungs.
  • Severe allergic reaction (anaphylaxis): rapid onset of hives, swelling, and breathing difficulty.

Precautions & Warnings

Use of Microgynon 50 requires careful consideration of several safety factors.

  • Contraindicated in pregnancy: product is Category X and must not be used by pregnant women.
  • Smoking and age over 35: increased risk of cardiovascular events.
  • History of thromboembolism: avoid use due to clotting risk.
  • Liver disease: use with caution as metabolism may be impaired.
  • Breastfeeding: consult a healthcare provider before use.
  • Store at ambient temperature: keep in the original pack, protect from moisture and heat.

Avoid Interactions

Microgynon 50 can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

  • Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): may reduce contraceptive effectiveness.
  • Rifampin and other antibiotics: may lower hormone levels.
  • Protease inhibitor antiretrovirals (e.g., ritonavir): may increase hormone concentrations and side‑effects.

Moderate Interactions (Monitor Closely)

  • Antifungal azoles (e.g., fluconazole): may raise hormone levels.
  • St. John’s wort: may decrease contraceptive efficacy.
  • Thiazide diuretics: may elevate risk of hypertension.

Frequently Asked Questions

Microgynon 50 is a combined oral contraceptive containing ethinylestradiol and levonorgestrel. It is prescribed to prevent pregnancy and to help regulate menstrual cycles in women of reproductive age.

Ethinylestradiol is a synthetic estrogen that binds to estrogen receptors, suppresses the hypothalamic‑pituitary‑gonadal axis, inhibits the luteinizing hormone surge, and stabilises the endometrium, all of which contribute to the contraceptive effect.

The dosage regimen is set by the prescribing healthcare professional. Typically, one tablet is taken daily at the same time for a 21‑day active phase followed by a 7‑day placebo interval, but exact instructions must follow the prescriber’s order.

Microgynon 50 is classified as pregnancy category X, meaning it must not be used during pregnancy. Use during breastfeeding should be discussed with a healthcare provider, as hormonal contraceptives are generally considered compatible but individual assessment is required.

Submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies institutional credentials, and then provides pricing, availability, shipping details and necessary import documentation.

Microgynon 50 contains a standard dose of 50 µg ethinylestradiol and 0.5 mg levonorgestrel, offering a balance of efficacy and tolerability. Compared with lower‑dose formulations, it may have a slightly higher risk of estrogen‑related side effects but provides reliable ovulation suppression.

Store at ambient temperature below 25 °C, in the original blister pack, protected from moisture and direct sunlight. Keep out of reach of children and do not use tablets that are discoloured or past the expiry date.

The tablet is taken orally with water, preferably at the same time each day. No food restrictions are required, but swallowing the tablet whole is recommended. Follow the prescriber’s schedule for active and placebo days.

Serious adverse events include venous thromboembolism, pulmonary embolism, myocardial infarction, stroke, and severe allergic reactions. Women with a history of clotting disorders, smoking over age 35, or certain cardiovascular conditions should avoid use.

Contraindications include current pregnancy, known or suspected breast cancer, active liver disease, uncontrolled hypertension, history of thromboembolic events, and smokers over 35 years of age. Patients with these conditions should discuss alternative contraception with their healthcare provider.
