Caduet (patient information)

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Generic Name: Amlodipine/Atorvastatin (am-LOE-di-peen/a-TOR-va-STAT-in)

Brand Name: Caduet

Overview

Caduet is used for treating patients who have high cholesterol and high blood pressure or chest pain. It may also be used for other conditions as determined by your doctor.

Caduet is a calcium channel blocker (amlodipine) and HMG-CoA reductase inhibitor (atorvastatin) combination. Amlodipine works by widening blood vessels to reduce chest pain and high blood pressure. Atorvastatin works to decrease your risk for heart attack and chest pain by lowering "bad" cholesterol (eg, triglycerides) and raising "good" cholesterol (eg, high-density lipoprotein [HDL]) in the blood.

Do NOT use Caduet if

• you are allergic to any ingredient in Caduet
• you have active liver disease or persistent high liver enzyme levels of unknown cause
• you are taking itraconazole, mibefradil, or an HIV protease inhibitor (eg, indinavir)
• you are pregnant or breast-feeding

Contact your doctor or health care provider right away if any of these apply to you.
