What SOMAVERT is used for

SOMAVERT is used to treat acromegaly, a disease caused by the body making too much growth hormone, which controls the growth of tissues, organs and bones. This leads to an enlargement of the bones (especially of the hands and feet), and other possible symptoms.
SOMAVERT is a product of biotechnology and contains the active substance pegvisomant. Pegvisomant is similar to human growth hormone, which exists naturally in the human body.
SOMAVERT works by blocking the action of the body's growth hormone.
Ask your doctor if you have any questions about why SOMAVERT has been prescribed for you.
Your doctor may have prescribed it for another reason.
SOMAVERT is not addictive.
SOMAVERT is available only with a doctor’s prescription.
