Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional.

Pasireotide is used to treat a certain condition (acromegaly) that occurs when the body makes too much of a certain natural substance called growth hormone. Treating acromegaly helps reduce the risk of serious problems such as diabetes and heart disease. Pasireotide works by decreasing the amount of growth hormone made in the body.
Pasireotide is also used to treat a certain condition (Cushing's disease) when surgery has not been fully successful or cannot be used to correct the condition. Cushing's disease occurs when the body makes too much of a certain hormone called cortisol. Having too much cortisol in the body may lead to high blood pressure, high blood sugar, and other problems. Pasireotide works by decreasing the amount of cortisol made in the body.
