Does the “maker” differ for tablets vs. other formulations?

Yes. For irbesartan, the active ingredient is the same, but different companies may manufacture different generic versions (often depending on who won market supply in a given region). Checking the product label (manufacturer name) is the most reliable way to confirm who made the specific tablets you have.

Best way to confirm the maker for the exact product you have

Look for the “Manufactured by” line on the bottle/box or the package insert. If you share the brand name (and strength, such as 150 mg or 300 mg) and your country, the specific manufacturer can usually be pinned down more precisely.
