Hydroxyzine is rapidly absorbed from the gastrointestinal tract and its bioavailability is about 70%. It crosses the blood-brain barrier and has sedative and anxiolytic effects. Its half-life is between 6.5 and 20 hours (mean: 11.4 hours).
Research on hydroxyzine’s effects in people is limited. However, in vitro and animal studies have shown that hydroxyzine has antispasmodic, sedative, antihistamine, cough suppressant, and local anesthetic effects. It also has been shown to inhibit the reuptake of serotonin and norepinephrine.
Atarax may be habit forming. Never share Atarax with another person, especially someone with a history of drug abuse or addiction. It is not known whether Atarax will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Hydroxyzine can pass into breast milk and may harm a nursing baby.
