Caduet Overview


Caduet is a prescription medicine used to treat people with high blood pressure and high cholesterol. It is a single tablet containing two medications, amlodipine and atorvastatin.

Amlodipine belongs to a group of medications called calcium channel blockers. It works by relaxing blood vessels so the heart does not need to pump as hard. Atorvastatin belongs to a group of medications called statins (or HMG-CoA reductase inhibitors). It works by blocking an enzyme that affects the rate of production of cholesterol in the body.

Caduet comes in a tablet form and is taken by mouth, once a day, with or without food.

Common side effects of Caduet include swelling, muscle pain, and diarrhea.

Certain statins can increase risk of muscle weakness as well. It is important to consult your physician to discuss the benefits and risks associated with using this medication.

Call your doctor right away if you:

  • have muscle problems like weakness, tenderness, or pain that happen without a good reason, especially if you also have a fever or feel more tired than usual
  • have nausea and vomiting, or stomach pain
  • are passing brown or dark-colored urine
  • feel more tired than usual
  • have yellowing of skin and white of your eyes
  • have allergic skin reactions
  • have chest pain that does not go away or gets worse

Sometimes, when you start Caduet or increase your dose, chest pain can get worse or a heart attack can happen. If this happens, call your doctor or go to the emergency room right away.

Caduet can cause allergic reactions including swelling of the face, lips, tongue, and/or throat that may cause difficulty in breathing or swallowing which may require treatment right away.

Do not use Caduet if you:

  • are allergic to any ingredient in Caduet
  • are pregnant or breastfeeding
  • have liver problems

Caduet may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol. Do not drive or operate heavy machinery until you know how this medication affects you.

Caduet Food Interactions

Eating grapefruit or drinking grapefruit juice may increase the amount of Caduet in your blood, which may increase your risk of serious side effects. Avoid large amounts of grapefruit juice.

Caduet and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant. Do not use amlodipine/atorvastatin if you are pregnant. It may cause harm to your unborn baby.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Caduet falls into category X. It has been shown that women taking Caduet during pregnancy may have babies with problems. There are no situations where the benefits of the medication for the mother outweigh the risks of harm to the baby. These medicines should never be used by pregnant women.

Caduet and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed. You should not use Caduet if you are breastfeeding. It may be excreted in your breast milk and may harm your nursing child.
