Product Description

Megestrol Acetate 20mg Tablets are oral prescription medications used for palliative management of advanced cancers such as breast and endometrial carcinoma. This synthetic progestational drug works by modifying hormone activity and suppressing tumor growth signals. It is available in tablet form for controlled dosing and is typically administered over a continuous treatment period to evaluate effectiveness.

Benefits

  • Palliative cancer care: Supports comfort-focused treatment in advanced or metastatic breast and endometrial cancers when curative options are limited.
  • Oral administration: Tablet form allows convenient dosing and flexible administration based on prescribed treatment regimens.
  • Flexible dosing range: Available dosing options enable tailored therapy depending on cancer type and patient response over time.
  • Progestational activity: Works through hormonal pathways to reduce estrogen-driven tumor progression and cellular proliferation.

Precautions

  • Thromboembolic caution: Use carefully in patients with history of thromboembolic disorders due to increased risk of serious complications.
  • Diabetic monitoring: May worsen existing diabetes and increase insulin requirements, requiring close monitoring of blood glucose levels.
  • Adrenal suppression risk: Chronic use may lead to adrenal insufficiency, especially during stress or withdrawal from therapy.

  • Renal function concern: Use carefully in patients with kidney problems, as the drug can build up in the body and increase the risk of side effects.

  • Cardiovascular issues: Heart-related problems such as weak heart function, high blood pressure, and body swelling can happen and may need medical attention.
