How Vistaril Works

Vistaril works in two primary ways:

• Blocks histamine (H1) receptors, helping reduce allergy symptoms such as itching and hives.
• Depresses activity in certain areas of the central nervous system, producing a calming effect that can reduce anxiety and promote relaxation.

Unlike benzodiazepines, hydroxyzine is not a controlled substance and does not work by affecting GABA receptors.
