Somavert (pegvisomant) is a man-made protein that is similar to human growth hormone. Pegvisomant binds to the same receptor in the body as growth hormone, and blocks the effects of growth hormone.

Somavert is used to treat acromegaly (a growth disorder caused by too much growth hormone).

Somavert is usually given after other medications, surgery, or radiation have been tried without successful treatment of symptoms.
