Indications & Clinical Uses

Megestrol acetate is a synthetic progestin used to address conditions associated with severe weight loss and hormone‑responsive tumors.

  • Cachexia associated with AIDS or cancer: improves appetite and promotes weight gain in patients experiencing disease‑related wasting.
  • Weight loss in chronic illness: helps increase body mass and nutritional status in patients with non‑cancer chronic conditions.
  • Hormone‑responsive cancers (breast, endometrial): used as part of therapy to inhibit tumor growth by anti‑estrogenic activity.

How It Works

  • Megestrol acetate acts as a synthetic progestogen that binds to intracellular progesterone receptors, modulating gene transcription. The receptor activation exerts anti‑estrogenic effects in hormone‑sensitive tissues, reducing estrogen‑driven proliferation. In addition, the drug influences hypothalamic pathways that increase appetite and promote anabolic processes, leading to weight gain. Its combined hormonal and metabolic actions underlie its use in cachexia and certain hormone‑dependent cancers.

Side Effects

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

Common Side Effects

  • Nausea: mild gastrointestinal upset.
  • Weight gain: excessive increase beyond therapeutic goal.
  • Edema: peripheral swelling due to fluid retention.
  • Hot flashes: transient vasomotor symptoms.
  • Hyperglycemia: elevated blood glucose levels.
  • Cushingoid appearance: facial rounding and central obesity.

Serious or Rare Side Effects

  • Thromboembolic events: deep vein thrombosis or pulmonary embolism.
  • Adrenal suppression: reduced cortisol production requiring monitoring.
  • Severe hypersensitivity: rash, angioedema, or anaphylaxis.
  • Liver dysfunction: abnormal hepatic enzymes or hepatitis.

Precautions & Warnings

When prescribing megesterol acetate, several safety considerations should be observed.

  • Dose titration: adjust based on clinical response and weight changes.
  • Monitoring: regularly assess blood glucose, lipid profile, and signs of fluid retention.
  • Thrombotic risk: avoid in patients with history of clotting disorders.
  • Hormone‑sensitive tumors: evaluate benefits versus potential tumor progression.
  • Pregnancy and lactation: contraindicated unless benefits outweigh risks.
  • Store at ambient temperature: keep below 25 °C, protect from moisture and light in original container.

Avoid Interactions

Megestrol acetate can interact with other medicines, requiring attention to potential effects.

Major Interactions (Avoid)

  • CYP3A4 inducers (e.g., rifampin): may reduce efficacy.
  • Anticoagulants (warfarin): increased risk of thrombosis.
  • Diabetic medications: may exacerbate hyperglycemia.

Moderate Interactions (Monitor Closely)

  • CYP3A4 inhibitors (e.g., ketoconazole): may increase plasma levels.
  • Other progestins or hormonal therapies: additive hormonal effects.

Frequently Asked Questions

Megoxi contains megesterol acetate, a synthetic progestin indicated for the management of severe weight loss associated with AIDS‑related or cancer‑related cachexia, for patients with chronic illnesses experiencing unintended weight loss, and as part of hormonal therapy for certain breast and endometrial cancers that respond to anti‑estrogenic treatment.

Megestrol acetate binds to intracellular progesterone receptors, altering gene transcription and producing anti‑estrogenic effects in hormone‑sensitive tissues. It also stimulates hypothalamic pathways that increase appetite and promote anabolic metabolism, helping patients gain weight while inhibiting estrogen‑driven tumor growth.

The appropriate dose of Megoxi is determined by the prescribing clinician based on the individual’s medical condition, severity of weight loss, and response to therapy. Dosage adjustments are made according to clinical monitoring and therapeutic goals.

Safety of megesterol acetate in pregnancy and lactation has not been established. It is generally contraindicated unless the potential benefit justifies the potential risk to the fetus or infant, and it should be used only under close medical supervision in such situations.

To order Megoxi, 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 and any necessary import documentation.

Megoxi (megestrol acetate) is a progestin‑based appetite stimulant, offering both weight‑gain and anti‑estrogenic benefits, which distinguishes it from agents such as dronabinol or mirtazapine that act primarily on central nervous system pathways. Its dual action makes it useful in cancer‑related cachexia and hormone‑responsive tumors, though it carries a higher risk of metabolic and thrombotic side effects.

Megoxi tablets should be stored at ambient temperature, preferably below 25 °C, in their original packaging to protect from moisture and light. Keep the product out of reach of children and avoid storing in areas with high humidity or direct sunlight.

Megoxi is taken orally as a tablet, usually with a glass of water. It can be taken with or without food, but consistency with meals may help reduce gastrointestinal discomfort. Patients should follow the dosing schedule prescribed by their healthcare provider.

The most serious risks associated with Megoxi include thromboembolic events such as deep‑vein thrombosis or pulmonary embolism, adrenal suppression leading to cortisol deficiency, severe hyperglycemia, and rare hypersensitivity reactions. Patients should be monitored regularly for signs of clotting, abnormal blood glucose, and any allergic symptoms.

Megoxi should be avoided in individuals with known hypersensitivity to megestrol acetate, active thromboembolic disease, uncontrolled diabetes, severe liver impairment, or in pregnant and breastfeeding women unless the benefits clearly outweigh the risks. It is also contraindicated in patients receiving concurrent high‑dose hormonal therapies without medical supervision.
