Atarax syrup is a sedative medication used to treat anxiety and can be used with other medicines for anesthesia. The medication may also be used to treat allergic skin reactions like hives.

Hydroxyzine is an antihistamine and sedative that inhibits chemicals called histamines in your body that cause you to have allergic reactions. The medication also affects the chemicals in your brain including serotonin to create a sedative effect. Thanks to these actions, Atarax syrup can relieve anxiety, promote drowsiness or relaxation, and help treat allergic reactions.
