Diltiazem manufacturers?

Which companies make diltiazem (brand-name and generic)?

Diltiazem is available from many manufacturers, including both branded products and multiple generic makers. The exact list of companies can vary by strength, dosage form (immediate-release vs extended-release), and country.

What diltiazem products should you check to find the right manufacturer?

Because diltiazem comes in different formulations, the manufacturer name depends on the specific product you’re looking at. Common product types include:
- Immediate-release diltiazem (often taken multiple times daily)
- Extended-release diltiazem (often once daily or fewer doses per day)

Checking the package label or the “manufacturer”/“marketed by” section on the pharmacy receipt is usually the fastest way to confirm the current maker for the exact product you received.

How to identify the manufacturer on your specific diltiazem prescription

Look for:
- The drug name plus strength (e.g., 120 mg/180 mg/240 mg)
- Dosage form (ER/LA/CD or IR)
- The manufacturer label or company listed next to “Manufactured for/Distributed by”

If you share the exact diltiazem name on your bottle (including ER/LA/CD and strength), I can narrow down which manufacturer(s) correspond to that specific product.
