In 2014, Myalept was approved by the FDA to be used along with a doctor-recommended diet to treat complications of not having enough leptin in people with generalized lipodystrophy (GL). It is not known if Myalept is safe and effective when used to treat problems caused by partial lipodystrophy or to treat liver disease, including non-alcoholic steatohepatitis (NASH). Myalept should not be used to treat people with HIV-related lipodystrophy or people with metabolic disease, including diabetes mellitus and hypertriglyceridemia, without signs or symptoms of congenital or acquired generalized lipodystrophy.
