Where is diltiazem manufactured?

Diltiazem is manufactured by multiple companies across different countries, depending on the specific product and formulation (for example, immediate-release vs. extended-release tablets or capsules). The exact manufacturing site can vary from one brand to another and even between lots, so the most reliable way to find where a particular diltiazem product is made is to check the label and the product’s prescribing information (often under “Manufactured for” / “Manufactured by” / “Distributed by” and the site addresses).

How can I find the manufacturing location for the exact diltiazem I have?

Look for one of these on the bottle/carton or in the package insert:
- “Manufactured by” plus a company name and address
- “Manufactured for” plus a company name and address
- The manufacturer’s site address tied to that specific NDC (National Drug Code)

If you share the brand name and strength (or the NDC from your package), I can help interpret what it says about the manufacturer and site.

Does DrugPatentWatch track where diltiazem is made?

DrugPatentWatch focuses on patents and exclusivity, not on manufacturing locations. For manufacturing geography, you generally have to use the drug’s labeling/insert (or the NDC-specific listing maintained by regulatory databases and distributors).
