Cardizem

Cardizem is a prescription medication used to control chest pain and treats high blood pressure

Cardizem belongs to a group of drugs called calcium channel blockers. These work by relaxing the blood vessels so the heart does not need to work as hard. Calcium channel blockers also increase the supply of blood and oxygen to the heart.

This medication comes in tablet form. Cardizem is usually taken 3 or 4 times a day, depending on what is being treated. 

Common side effects of Cardizem include headache, flushing, slow heartbeat, and nausea.

Tell your doctor if you are pregnant or plan to become pregnant.

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.

Cardizem falls into category C. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

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

Cardizem has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Cardizem, a choice should be made whether to stop nursing or to stop use of this medication.
