Is cardizem the same as diltiazem?

Yes. Cardizem is a brand name for diltiazem.

• Cardizem = diltiazem (same active medication)
• You may also see other brand/generic forms like Cardizem CD, Cardizem SR, etc., which differ in release formulation (extended-release vs. other types), but the underlying drug is still diltiazem.

If you tell me the exact Cardizem label (e.g., CD/SR/IR) and your dose, I can help confirm how it compares to a specific diltiazem product.
