Medical Use
As of June 2023, megestrol is being used to treat significant weight loss in HIV/AIDS patients, and as a palliative treatment of endometrial and breast cancers . It can be administered in both tablet and oral suspension forms, with dosages ranging from 100 mg/day to 1600 mg/day depending on the condition being treated.[ 3]
