Cardizem (Diltiazem) – What It Is and How It Helps

Cardizem is the brand name for diltiazem, a calcium‑channel blocker that relaxes blood vessels and slows the heart down a bit. Doctors prescribe it for high blood pressure, angina (chest pain), and certain heart rhythm problems. By easing the workload on the heart, Cardizem can lower the risk of complications and improve daily comfort.

How to Take Cardizem the Right Way

Most people start with a low dose, usually 30 mg to 60 mg, taken once or twice a day. Your doctor will adjust the amount based on your blood pressure readings and how you feel. It’s important to take the tablet at the same times each day – that keeps the drug level steady in your system. If you miss a dose, take it as soon as you remember, but skip it if it’s almost time for the next one. Never double up.

Swallow the tablet whole with a glass of water; don’t crush or chew it unless your doctor says it’s an extended‑release form that can be split. Some people feel a bit dizzy or have a mild headache when they start; those signs usually fade after a few days as your body gets used to the medication.

Common Side Effects and When to Call the Doctor

Typical side effects include a slow heartbeat, low blood pressure, swelling in the ankles, and mild constipation. If you notice sudden swelling, a rapid weight gain, or a fainting spell, call your doctor right away. Severe chest pain, difficulty breathing, or a rash that spreads should also trigger a call – they could signal a rare but serious reaction.

Alcohol can make the blood‑pressure‑lowering effect stronger, so keep drinking low or avoid it while on Cardizem. Grapefruit juice has a similar effect; it can raise diltiazem levels and increase side‑effect risk, so it’s best to skip it.

Always tell your doctor about other medicines you take. Certain antibiotics, antifungals, and other heart drugs can interact with Cardizem, changing how well it works or raising side‑effect chances. A quick chat with your pharmacist can clear up any doubts.

In short, Cardizem is a solid tool for managing heart‑related issues when you follow the dosing schedule, watch for side effects, and keep an open line with your healthcare team. If you have any questions or notice something odd, don’t wait – reach out to your doctor. Your heart will thank you.
