Vistaril and Xanax are two brand-name medications used for the treatment of short-term anxiety. Anxiety disorders affect approximately 40 million Americans, making it one of the most common mental illnesses. Unfortunately, statistics show only about 40% of patients seek treatment for their anxiety despite the fact that it is highly treatable.

There are a variety of types of treatment for anxiety. Cognitive-behavioral therapy focuses on identifying, understanding, and changing your thinking and behavioral patterns to help you better cope with your anxiety. Alternative treatments such as yoga, meditation, and acupuncture have proven effective for some in alleviating anxiety. Treatment with medication remains a predominant mode of treatment for anxiety.

There are several classes of medications indicated in the treatment of anxiety including selective serotonin reuptake inhibitors (SSRIs), selective norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, and benzodiazepines. Your healthcare provider may recommend a combination of treatment types based on your symptoms.

Conditions treated by Vistaril and Xanax

Vistaril is indicated in the treatment of anxiety, tension, and psychomotor agitation in conditions of emotional distress. Due to its actions on histamine receptors, Vistaril is also indicated in treating pruritus (itching) due to conditions of chronic urticaria, contact dermatitis, and atopic dermatitis. Vistaril is used in the treatment of nausea and vomiting due to both pregnancy and post-operative causes. It is also approved to provide sedation for procedures.

Vistaril is also used off-label for some indications. Off-label use refers to drugs being used for indications not approved by the Food and Drug Administration (FDA). Vistaril is used off-label for the temporary treatment of insomnia due to its somnolence effects. It is also used off-label to treat seasonal allergic rhinitis (season allergies).

Xanax is indicated in the treatment of transient symptoms of anxiety as well as generalized anxiety disorder (GAD). It is also indicated in the treatment of panic disorder. Xanax can be used off-label to relieve anxiety and mood disorders related to premenstrual dysphoric disorder (PMDD).

Is Vistaril or Xanax more effective?

A double-blind, controlled clinical study compared the anxiolytic, sedative, amnesia, and safety effects of the ingredients of Vistaril and Xanax on pre-procedural patients. This study found that Vistaril produced essentially no effect on anxiety for these patients, compared to a moderate effect produced by Xanax. The two drugs were comparable in regards to effects in somnolence and memory, but the effects of hydroxyzine lead to a more pronounced decrease in blood pressure. While they are both effective pre-procedural drugs, Xanax may be preferred due to its more pronounced effect on anxiety and adverse event profile.

Only your doctor can decide which anxiety treatment is best for you. If you are experiencing anxiety or other symptoms of a mental health disorder, seek medical advice. Do not attempt to self-medicate or take over-the-counter medications.

Drug interactions of Vistaril vs. Xanax

Vistaril should be avoided with both long- and short-acting beta agonists, such as albuterol or formoterol. Beta agonists are linked to the incidence of QT prolongation and Torsade de Pointes, and concurrent use with Vistaril increases the risk of these adverse events.

Vistaril and Xanax combined with opioid agonists may greatly increase the risk of severe drowsiness and somnolence. Xanax combined with opioid agonists may lead to severe respiratory depression and hypotension (low blood pressure). This can be life-threatening. Combined use with drugs such as codeine or hydrocodone can be dangerous and should be avoided.

Vistaril and Xanax should be used cautiously in patients on other antihistamines that may be sedating, such as diphenhydramine or chlorpheniramine. The additive drowsiness of these medications can cause harm to the patient.

Warnings of Vistaril and Xanax

It is unknown if Vistaril crosses into breast milk, and therefore should be avoided or used cautiously in nursing mothers.

Concomitant use of Xanax with opioid agonists can cause life-threatening respiratory depression and hypotension. In some cases, it may lead to coma and/or death. If it is determined that the combination cannot be avoided, patients must be advised on the adverse events. Patients should not drive or operate heavy machinery while on these medications.

Xanax is a controlled substance and could be habit-forming. The use of Xanax carries the risk of physical dependence and substance abuse, even after a relatively short-term treatment. Your doctor may limit the amount of Xanax prescribed to reduce this risk.

Withdrawal symptoms, including seizures, may occur with dose decrease or discontinuation of Xanax. This medication should be tapered with the advice of a medical professional while they monitor the patients for signs and symptoms of withdrawal.
