Hydroxyzine

What is this medication?

This medicine contains hydroxyzine, an antihistamine that reduces activity in the central nervous system. Because of this effect, hydroxyzine is commonly used to relieve symptoms such as hives, itching, sneezing, and a runny nose. Hydroxyzine is also widely prescribed to help manage anxiety, tension, nausea, and vomiting.

Classification and Mechanism of Action

Hydroxyzine works by blocking histamine receptors, which helps reduce allergic reactions and skin conditions such as dermatitis.
It also has sedative and calming effects on the brain, which makes hydroxyzine useful for reducing anxiety and promoting relaxation. Many patients experience noticeable improvement soon after starting hydroxyzine.
