Long-term treatment with Megace® ES (megestrol acetate) may increase the risk of respiratory infections. A trend toward increased frequency of respiratory infections, decreased lymphocyte counts and increased neutrophil counts was observed in a two-year chronic toxicity/carcinogenicity study of megestrol acetate conducted in rats.
OVERDOSAGE
No serious unexpected side effects have resulted from studies involving megestrol acetate oral suspension administered in dosages as high as 1200 mg/day. Megestrol acetate has not been tested for dialyzability; however, due to its low solubility it is postulated that dialysis would not be an effective means of treating overdose.
CONTRAINDICATIONS
History of hypersensitivity to megestrol acetate or any component of the formulation. Known or suspected pregnancy.
