Myalept is a prescription medication that replaces leptin, an important hormone that people with generalized lipodystrophy (GL) are missing. It’s used with a doctor-recommended diet and treats problems caused by not having enough leptin in people with GL.
Leptin is a hormone normally present in the body. But people with GL have low levels of leptin, which causes health problems.
If you have GL, Myalept replaces the leptin the body is missing. Because Myalept acts similarly to the body’s naturally occurring leptin, it can help treat some of the problems associated with GL.
What is Myalept?
