Important: How To Use This Information

This information is not individual medical advice and does not substitute for the advice of your health care professional.

Uses

Pasireotide is 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.

Precautions

Before using pasireotide, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:

  • liver disease
  • heart problems (such as irregular heartbeat, heart block)
  • diabetes
  • gallbladder problems (such as gallstones)

Pasireotide may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using pasireotide, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:

  • certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
  • family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using pasireotide safely.

This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation.
