- low blood pressure; or
- if you have recently had a heart attack.
To make sure you can safely take diltiazem, tell your doctor if you have any of these other conditions:
- kidney disease;

FDA pregnancy category C. It is not known whether diltiazem will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
Diltiazem can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take diltiazem?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Take diltiazem with a full glass of water.
Do not crush, chew, break, or open an extended-release tablet or capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.
If you have trouble swallowing a diltiazem capsule whole, ask your doctor or pharmacist if it is safe for you to open the capsule and sprinkle the medicine into a spoonful of applesauce to make swallowing easier. Swallow this mixture right away without chewing. Do not save the mixture for later use. Discard the empty capsule.
Use diltiazem regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Do not stop taking this medication without first talking to your doctor. If you stop taking diltiazem suddenly, your condition may become worse.
If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
Diltiazem may be only part of a complete program of treatment that also includes diet, exercise, and other medications. Follow your diet, medication, and exercise routines very closely.
To be sure this medicine is helping your condition and is not causing harmful effects, your blood pressure will need to be checked often. Your liver and kidney function may also need to be tested. Visit your doctor regularly.
Store at room temperature away from moisture and heat.
