Some considerations for people taking diltiazem include:
Diltiazem comes in the form of a capsule or tablet. Diltiazem is taken by mouth, one to four times daily, depending on the particular diltiazem product.
You can take most diltiazem products with or without food. However, Dilacor XR®, Diltia XT®, and Dilt-XR® capsules should be taken on an empty stomach. Regular Cardizem tablets (not Cardizem CD® or Cardizem LA®) should be taken before meals.
Diltiazem capsules are extended release and should not be crushed or chewed. Be sure to swallow them whole. However, Tiazac® and Taztia XT® capsules can be opened, and you can sprinkle the contents onto a spoonful of applesauce. The applesauce should not be hot, and you should immediately swallow it whole (without chewing); follow the applesauce with a glass of water.
Cardizem LA® tablets are extended release and should not be cut, crushed, or chewed.
Diltiazem should be taken at the same time(s) each day to maintain an even level of the drug in your blood.
For diltiazem to work properly, it must be taken as prescribed. Diltiazem will not work if you stop taking it.
