Diltiazem other names?

What other names does diltiazem go by?

Diltiazem is sold under multiple brand names and may appear in lists as different “other names” depending on the manufacturer and formulation (immediate-release vs. extended-release). Common brand-name alternatives include:

- Cardizem
- Cardizem CD
- Cardizem LA

It may also be listed by the generic name “diltiazem” plus a formulation-specific label (for example, “extended-release” or “extended release”), which can change what shows up on pharmacy and prescription records.

What’s the difference between generic diltiazem and brand-name versions?

The active ingredient is the same, but brands usually correspond to a specific drug product design (such as extended-release). That matters for dosing schedules and how quickly the medicine works.

How can you find the exact “other names” for your specific prescription?

Check the label for:
- The exact spelling of the generic name (diltiazem)
- Any suffix like “CD” or “LA”
- Whether it says “extended-release,” “extended release,” or “immediate-release”

If you share the exact label wording (brand/suffix and whether it’s ER or IR), I can map it to the corresponding generic and common alternatives.
