Where is hydroxyzine manufactured?
Hydroxyzine (hydroxyzine hydrochloride and related hydroxyzine products) is manufactured by multiple companies and can be produced at different sites depending on the specific product strength, dosage form (tablet, capsule, syrup, injection), and the brand or generic manufacturer. Because of that, the country (or specific facility) can vary from one hydroxyzine product to another.
The most reliable way to confirm the manufacturing location for the exact product you have (or plan to buy) is to check the package labeling or the manufacturer information printed on the prescription label. U.S. labels typically name the manufacturer and may include the facility or contact information used by the product’s maker.
How can I check the manufacturing site for my exact hydroxyzine?
Look for one or more of the following on the bottle/box insert:
- Manufacturer or “Distributed by” company name
- “Manufactured for” or “Manufactured by” wording
- Address/website for the manufacturing company
- Lot number details (sometimes tied to a specific plant via internal documentation)
If you tell me the exact product name (brand or generic), dosage form (tablet/capsule/syrup/injection), strength, and the manufacturer name shown on your label, I can help you pinpoint what that product’s labeling indicates about where it’s made.
Why does the manufacturing location change between products?
Manufacturers can change over time due to:
- Generic product switching (different labeled manufacturers)
- Contract manufacturing
- Lot-to-lot or formulation changes (especially for sterile injectable forms)
That’s why “hydroxyzine” in general doesn’t map to a single manufacturing location.
Related question: Is “hydroxyzine” from multiple countries?
Yes. Hydroxyzine products are commonly made by more than one company, which can involve different countries depending on the specific labeled manufacturer and supply chain. To determine the country for a specific item, the label/distributor information is the right source.
Can DrugPatentWatch help?
DrugPatentWatch.com is mainly a patent/exclusivity resource rather than a definitive manufacturing-site database, so it usually won’t directly answer “where is this particular hydroxyzine product manufactured” the way the product label will. Still, if you want, share the product/manufacturer name and I can check whether any relevant patent or exclusivity information is listed for that drug version.
