Frequently asked questions about diltiazem ER

What is diltiazem ER?

Diltiazem extended-release capsules are used to treat high blood pressure (hypertension) and to control chest pain (angina). They belong to a class of medications known as calcium-channel blockers.

High blood pressure is a common but serious disease. When not treated, it can lead to serious complications such as heart disease, heart attacks, kidney failure, loss of vision, strokes, and more. While medications such as diltiazem are effective in helping lower blood pressure, doctors often prescribe these medicines alongside recommended lifestyle changes, like improving your diet, increasing your exercise, and abstaining from alcohol and tobacco.

What is diltiazem ER used to treat?

Diltiazem ER is used alone or with other antihypertensive medications to treat high blood pressure (hypertension). It is also used to prevent chest pain (known as angina) - making it easier for you to exercise while decreasing the frequency of your angina attacks. Diltiazem is also sometimes used to treat certain types of arrhythmias (abnormal heart rhythms). This medication may be prescribed for other uses as well. Talk to your doctor or pharmacist for more information.

How does diltiazem ER work?

Diltiazem belongs to a class of medications known as calcium-channel blockers. It works by preventing calcium from entering the cells of your heart and arteries. Calcium causes the heart and arteries to contract more strongly. Blocking the uptake of calcium helps the blood vessels to relax and open up. This lowers blood pressure and helps the heart deliver more blood and oxygen to your body with less effort.

What are the most common side effects of diltiazem ER?

The most common side effects associated with diltiazem are dizziness, headache, weakness, slow heartbeat, vomiting, diarrhea, constipation, nasal congestion, and a cough. Tell your doctor if any of these are severe or do not go away.

Rare, more serious adverse events have also been known to occur. Get immediate medical attention if you experience any new or worsening symptoms of heart failure (such as swelling of the feet/ ankles, shortness of breath, sudden weight gain, or unusual tiredness); mood changes; an abnormal heartbeat; severe abdominal pain; dark urine; yellowing eyes or skin; persistent vomiting; or any signs of an allergic reaction (such as rash; hives; itching; swelling of the face, tongue, or throat; or difficulty breathing or swallowing).

Talk to your doctor about your medical history - particularly if you have or have ever had a narrowing or blockage of your digestive system or any other condition that causes food to move through your digestive system more slowly; a heart attack; low blood pressure; or heart, liver, or kidney disease. Inform your doctor of all known allergies and of all medications, supplements, and herbal products that you take. Tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding.

This is not a complete list of side effects or precautions. For more information please visit the National Institutes of Health’s DailyMed webpage for diltiazem ER.

What is the typical starting dose of diltiazem ER?

Your starting dose will depend on the condition you are treating, your body’s response to the treatment, other medications you may be taking, and more. Follow the instructions on the packaging label carefully and ask your doctor or pharmacist if there are any parts that you do not understand. Take diltiazem ER only as directed.

Do not crush or chew extended-release tablets. This releases all of the drug at once, increasing the risk of side effects.
