Amlodipine and Benazepril

Amlodipine and benazepril is a prescription medication used to treat high blood pressure. It is a single product containing 2 medications: amlodipine and benazepril. Amlodipine is in a class of medications called calcium channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. Benazepril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors.  It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly.

This medication comes in capsule form and is taken once a day, with or without food.

Common side effects of amlodipine and benazepril include dizziness, cough, and swelling of the feet, ankles, or hands. Do not drive or operate heavy machinery until you know how amlodipine and benazepril affects you.

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.

Amlodipine and benazepril falls into category D. It has been shown that use of amlodipine and benazepril in pregnant women caused some babies to be born with problems. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby. See FDA Warning section for more information.

Tell your doctor if you are breastfeeding or plan to breastfeed.

Minimal amounts of benazepril are excreted into the breast milk. It is unknown whether amlodipine is excreted in human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risks of using amlodipine and benazepril.
