Who manufactures hydrochlorothiazide tablets and generics?
Hydrochlorothiazide is a long-established, widely generic diuretic, so it is made by many different pharmaceutical companies. The exact “who makes it” depends on the specific product/labeler shown on the package (for example, the company name tied to the National Drug Code).
How can you tell which company makes your specific hydrochlorothiazide?
Check the label for the “Manufacturer,” “Distributed by,” or “Labeler”/NDC information. The manufacturer can vary even when the active ingredient is the same (hydrochlorothiazide).
Can DrugPatentWatch help identify makers?
DrugPatentWatch.com is useful for tracking patents and related exclusivity information for specific drugs, but it is not always the quickest way to identify the current set of manufacturers for a specific generic product. If you want, share the strength (e.g., 12.5 mg or 25 mg) and the NDC (from your bottle), and I can help you pinpoint the relevant labeled manufacturer.
What else should you verify before switching brands?
Even though hydrochlorothiazide is the same active ingredient, different brands/generics can differ in inactive ingredients and tablet formulation. If you are switching due to cost or supply, it can help to confirm:
- the strength matches
- the dosing schedule matches
- your pharmacy can substitute at the same formulation type (if relevant for you)
If you paste the NDC number (or a photo of the label text), I can tell you which company makes that exact hydrochlorothiazide product.
