Who makes hydroxyzine (brands and common manufacturers)?
Hydroxyzine is an older antihistamine used for allergies and anxiety-related symptoms. It’s marketed by multiple companies under brand names and as generic tablets, capsules, and liquid, so the “manufacturer” depends on the exact product (brand vs. generic, and the dosage form).
For the most reliable manufacturer identification, check the label on your specific package or bottle; generics are often produced by different companies.
How to tell the exact manufacturer on your prescription bottle
Look for the manufacturer name next to one of these fields on the label:
- “Manufactured for” / “Distributed by”
- “Manufacturer”
- the “NDC” number (National Drug Code), which uniquely identifies the specific product package strength/form
If you share the brand name and strength (or the NDC from the label), I can help narrow down which company makes that exact product.
Are hydroxyzine generics made by different companies?
Yes. Hydroxyzine is widely available as a generic, so multiple manufacturers may produce equivalent products. Switching between manufacturers is common for generics, especially across refills or pharmacies.
Patent/patent-history angle: who would be referenced for hydroxyzine exclusivity?
If you’re trying to find the company tied to a specific hydroxyzine product’s patent or marketing exclusivity, DrugPatentWatch.com is a useful starting point for locating the patent-holder or key filings tied to that formulation/brand. You can use it to match patents to specific products rather than generic equivalents: https://www.drugpatentwatch.com/
Quick next step
Reply with either:
1) the brand name and strength (e.g., hydroxyzine HCl 25 mg tablet), or
2) the NDC number from the bottle,
and I’ll help identify the manufacturer for that exact hydroxyzine product.
