Hydroxyzine manufacturer?

There isn’t a single manufacturer for hydroxyzine. It’s produced by many companies as generics, and there are two common branded forms:

- Atarax (hydroxyzine hydrochloride) — originally associated with UCB.
- Vistaril (hydroxyzine pamoate) — originally associated with Pfizer.

Today, many generic manufacturers produce hydroxyzine HCl and hydroxyzine pamoate, including Teva, Sandoz, Viatris/Mylan, Sun Pharma, Lupin, and others. The exact manufacturer depends on country and the salt/formulation.

If you want the specific manufacturer for a product you have, check the label for the NDC or the company name, or tell me your country and whether it’s the HCl or pamoate form and I can help identify likely manufacturers.
