What is diltiazem and how does it work?

Diltiazem hydrochloride is a calcium channel blocker in the nondihydropyridine (benzothiazepine) group. It relaxes blood vessels and slows the electrical signals that set your heart rate, which lowers blood pressure and eases the heart's workload. Extended-release and sustained-release oral forms are FDA-approved to treat high blood pressure (hypertension) and chronic stable angina, as well as angina caused by coronary artery spasm (Prinzmetal or variant angina).

Given intravenously in a hospital, diltiazem is approved for short-term rate control in atrial fibrillation or atrial flutter and to help convert paroxysmal supraventricular tachycardia (PSVT). It is also very commonly used to slow the heart rate in atrial fibrillation. It is sold under brand names including Cardizem, Cardizem CD, Cardizem LA, Cartia XT, Tiazac, Taztia XT, Dilt-XR, and Matzim LA.

Cost and savings: what diltiazem HCl runs without insurance

Diltiazem is available as an FDA-approved, substitutable generic, so it is generally affordable even if you pay cash without insurance. The catch is that pharmacies set their own cash prices, and the difference between the cheapest and most expensive pharmacy for the exact same prescription can be surprisingly large. That is why comparing before you fill matters.

Diltiazem vs. related medications

Diltiazem's brand versions include Cardizem and long-acting products such as Cartia XT and Tiazac; the generic is substitutable for these. Another nondihydropyridine calcium channel blocker with similar heart-rate-slowing effects is verapamil.

Your prescriber may consider other options depending on whether the goal is blood pressure, angina, or heart-rate control. Amlodipine is a different (dihydropyridine) calcium channel blocker used mainly for blood pressure and angina, and metoprolol is a beta-blocker often used for rate control and other heart conditions. These are not interchangeable, so only change medications on your provider's advice.

Safety and side effects

Diltiazem has no boxed warning, but it can slow the heart too much, causing bradycardia, AV block, or low blood pressure. It should not be used in people with sick sinus syndrome or second- or third-degree AV block without a pacemaker, in a recent heart attack with fluid in the lungs, or in severe low blood pressure or cardiogenic shock. It is generally avoided in significant heart failure with a reduced ejection fraction because it can weaken the heart's pumping. Common side effects include swelling in the ankles or feet (peripheral edema), dizziness, and constipation; rarely it can cause serious skin reactions or raised liver enzymes.

Do not stop diltiazem suddenly, and swallow extended-release forms whole. It has major CYP3A4 drug interactions (for example certain statins, some beta-blockers, and amiodarone), and combining it with a beta-blocker raises the risk of a very slow heartbeat or AV block.
