If you’ve been prescribed Cardizem, you’re probably wondering what it does and whether it’s safe for you. Cardizem is the brand name for diltiazem, a calcium‑channel blocker that helps relax blood vessels and slow down the heart. Doctors often use it to treat high blood pressure, angina (chest pain), and certain rhythm problems.
Diltiazem blocks calcium from entering the muscle cells of your heart and arteries. Less calcium means the muscles can’t contract as hard, so your heart beats more calmly and your blood vessels stay wider. That drop in force lowers blood pressure and eases the chest pain that comes from a heart that’s working too hard.
Typical reasons doctors write a Cardizem prescription include:
The drug comes in several forms: immediate‑release tablets, extended‑release tablets, and a mouth‑disintegrating version. Your doctor will choose the form based on how fast they want the effect and how often you’ll take it.
Dosage basics. Most adults start with 30–60 mg taken 2–3 times a day for the immediate‑release tablets. Extended‑release versions often start at 120 mg once daily. Never change the dose without talking to your doctor.
Side effects you might notice. The most common are headache, flushing, swelling in the ankles, and a slower heartbeat. If you feel dizzy, have a very slow pulse (under 50 bpm), or notice unusual bruising, call your doctor right away.
Drug interactions. Cardizem can boost the levels of certain meds like statins (especially simvastatin) and some anti‑arrhythmics. Alcohol can make the blood‑pressure‑lowering effect stronger, so keep drinking moderate.
Pregnancy and breastfeeding. The safety data are limited, so discuss any plans with your healthcare provider. In most cases, doctors weigh the benefits against potential risks.
What to do if you miss a dose. Take it as soon as you remember, unless it’s almost time for the next dose. In that case, skip the missed one – don’t double up.
Overall, Cardizem is a well‑studied medication that can make a big difference for people with heart‑related conditions. The key to a good outcome is following the prescribed schedule, watching for side effects, and keeping an open line with your doctor.
Got more questions? Talk to your pharmacist or physician. They can clarify dosage tweaks, check for interactions with any over‑the‑counter supplements you take, and help you stay on track with your heart health.
