Indications & Clinical Uses

Megestil (megestrol acetate) acts as a progestogenic hormone therapy used in specific oncologic and wasting conditions.

  • Cachexia (AIDS or cancer): improves appetite, promotes weight gain, and helps stabilize nutritional status in patients experiencing severe wasting.
  • Breast cancer: provides antigonadotropic effects that can help control hormone‑responsive tumor growth and may be used in advanced disease settings.
  • Endometrial cancer: used as part of hormonal management to inhibit disease progression, particularly in patients unsuitable for surgery or radiation.

How It Works

  • Megestrol acetate is a synthetic progestogen that binds to intracellular progesterone receptors, producing antigonadotropic effects that suppress estrogen and androgen production. The receptor activation also exerts glucocorticoid‑like activity, enhancing appetite and promoting protein synthesis. Through these combined actions, the drug modulates hormonal pathways involved in tumor growth and counteracts catabolic states associated with chronic illness.

Side Effects

Megestil may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

  • Nausea
  • Edema
  • Weight gain
  • Fatigue

Serious or Rare Side Effects

  • Thromboembolic events
  • Hyperglycemia
  • Severe allergic reactions (anaphylaxis)

Precautions & Warnings

When using Megestil, consider the following precautions:

  • Monitor weight and fluid status: assess for excessive weight gain or edema regularly.
  • Check blood glucose: screen for hyperglycemia, especially in diabetic patients.
  • Evaluate for thromboembolic risk: consider prophylaxis in high‑risk individuals.
  • Observe adrenal function: prolonged use may suppress cortisol production.
  • Review concomitant hormone therapies: avoid additive hormonal effects.
  • Store at ambient temperature: keep below 25 °C, in original packaging, protected from moisture.

Avoid Interactions

Megestil can interact with other medicines; awareness of major and moderate interactions helps ensure safety.

Major Interactions (Avoid)

  • Anticoagulants (warfarin): may increase bleeding risk.
  • CYP3A4 inducers (rifampin, carbamazepine): can reduce drug exposure.
  • Strong glucocorticoids: additive immunosuppressive effects.

Moderate Interactions (Monitor Closely)

  • Antidiabetic agents: may exacerbate hyperglycemia.
  • Hormonal contraceptives: may decrease contraceptive efficacy.
  • Digoxin: potential alteration of serum levels.

Frequently Asked Questions

Megestil contains megestrol acetate, a progestin indicated for the management of cachexia associated with AIDS or cancer, and as part of hormonal therapy for certain breast and endometrial cancers. It helps improve appetite, promote weight gain, and may slow the progression of hormone‑responsive tumors.

Megestrol acetate binds to intracellular progesterone receptors, producing antigonadotropic effects that lower estrogen and androgen levels. It also has glucocorticoid‑like activity, which stimulates appetite and protein synthesis, thereby counteracting catabolic states and influencing hormone‑driven tumor growth.

The appropriate dose of Megestil is individualized by the prescribing clinician based on the specific indication, severity of the condition, patient weight, renal and hepatic function, and any concomitant therapies. Dosage regimens are not standardized and should follow the prescriber’s written order.

The safety of megestrol acetate in pregnancy and lactation has not been established. Because the drug can affect hormonal balance, it is generally avoided in pregnant or nursing women unless the potential benefit outweighs the potential risk, as determined by a qualified health professional.

To order Megestil, 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 trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Megestil (megestrol acetate) is a progestogenic appetite stimulant, whereas other cachexia therapies may include corticosteroids, ghrelin mimetics, or nutritional interventions. Compared with corticosteroids, megestrol often provides longer‑lasting appetite improvement with a different side‑effect profile, but individual response varies and treatment choice depends on patient factors.

Megestil tablets should be stored at ambient temperature, below 25 °C, in the original container to protect from moisture and light. Keep the product out of reach of children and avoid storing in bathrooms or other humid environments.

Megestil is taken orally, usually with or without food, as directed by the prescribing clinician. The tablet should be swallowed whole with a glass of water and not crushed or chewed unless specifically instructed.

Serious risks include thromboembolic events such as deep‑vein thrombosis or pulmonary embolism, significant hyperglycemia that may require medical intervention, and severe allergic reactions including anaphylaxis. Patients should seek immediate medical attention if they experience sudden swelling, shortness of breath, high blood sugar symptoms, or signs of an allergic reaction.

Megestil is contraindicated in individuals with known hypersensitivity to megestrol acetate or any excipients, in patients with active thromboembolic disease, uncontrolled diabetes, or severe liver dysfunction. It should also be used with caution in patients receiving other hormonal agents or anticoagulants, and only under medical supervision.
