Common brand and generic “other names” for diltiazem
Diltiazem is available under multiple brand names and sometimes appears as different salt forms. Common names people may see include:
- Cardizem (brand)
- Cardizem CD (controlled-delivery form)
- Cardizem LA (long-acting form)
- Tiazac (brand)
- Dilacor XR (extended-release brand)
- Dilt-XR (extended-release brand)
Why you might see different names on the label (even though it’s the same drug)
Different “other names” usually reflect the manufacturer’s brand or the formulation:
- Extended-release vs immediate-release can show up as XR, CD, LA, or similar label wording.
- Some listings may describe the drug by its formulation type (for example, extended-release), even if the active ingredient is still diltiazem.
How to make sure it’s the same medication at the pharmacy
If you want to confirm two prescriptions are equivalent, check for:
- The active ingredient: “diltiazem”
- The dosage form/labeling (immediate-release vs extended-release), since these are not always interchangeable unit-for-unit.
Search tip: what to look up if you’re trying to identify a pill
If you’re searching based on a pill impression, packaging, or local formulary, look for the text “diltiazem” plus the release type (IR vs XR/LA/CD). That usually narrows it down to the exact product.
