What should I know about diltiazem before taking it?

Before you take diltiazem, you should know that it can cause an allergic reaction in some people and that your ability to think or react quickly may be impaired, which could affect your ability to drive or operate machinery.

In addition, tell your doctor if you have had a heart attack; have low blood pressure or heart disease; have kidney or liver disease; or have a blockage or other digestive problem that causes food to move slowly through your GI tract. Your doctor should also know if you’re planning to become pregnant, are pregnant or are breastfeeding, as well as if you will be having surgery or dental work. Don’t forget to give your doctor a list of all the drugs you take, including over-the-counter (OTC) medications and nutritional supplements, when discussing whether diltiazem is right for you.

Once you begin treatment with diltiazem, you cannot stop taking the medication without first talking to your doctor because your blood pressure could get worse. In addition to diltiazem, your doctor will likely recommend changes to your diet and increased exercise to manage your high blood pressure effectively.
