Tesamorelin is a synthetic form of growth hormone-releasing hormone (GHRH) that is used to reduce excess fat in the stomach area (abdomen) in people with HIV infection who have changes in the way their body fat is distributed. This condition is also called lipodystrophy (LYE-poe-DIS-troe-fee). Tesamorelin is not used to help with weight loss.
Tesamorelin is thought to work by increasing the production of growth hormone, which can help to reduce body fat and improve body composition. Tesamorelin is given by injection under the skin (subcutaneously) once a day.
Tesamorelin is generally well-tolerated, but some people may experience side effects such as headache, dizziness, nausea, and injection site reactions. Tesamorelin is not recommended for pregnant or breastfeeding women.
Tesamorelin was approved by the US Food and Drug Administration (FDA) in 2010. It is marketed under the brand name Egrifta.
Uses of Tesamorelin
