Vistaril is the brand name for hydroxyzine pamoate, a first-generation antihistamine that has been used since the 1950s. It belongs to the piperazine class of antihistamines and is available by prescription only in the United States.
Hydroxyzine is FDA-approved for the symptomatic relief of anxiety and tension associated with psychoneurosis, the management of allergic pruritus (itching) from conditions such as chronic urticaria and atopic dermatitis, and as a preoperative and postoperative sedative. It is also used off-label for insomnia, nausea, and alcohol withdrawal management.
Unlike benzodiazepines such as Xanax or Ativan, hydroxyzine is not a controlled substance. It does not carry the same dependence risk, which makes it a commonly prescribed option for patients where controlled substances are not appropriate.

Vistaril (hydroxyzine) works primarily by blocking histamine H1 receptors in the body and brain. Histamine is a chemical messenger involved in allergic reactions, wakefulness, and emotional regulation. By blocking histamine at peripheral receptors, hydroxyzine reduces itching and allergic symptoms. By blocking central H1 receptors in the brain, it suppresses arousal centers and produces its calming, sedative effect.
Hydroxyzine also suppresses activity in subcortical regions of the central nervous system, which contributes to its anxiolytic effect. This mechanism is distinct from benzodiazepines (which work through GABA) and SSRIs (which work through serotonin). Additionally, hydroxyzine has anticholinergic properties, which can cause dry mouth and sedation.
Hydroxyzine is rapidly absorbed after oral administration, with clinical effects noticeable within 15-30 minutes. Its elimination half-life is approximately 20 hours in adults, though CNS effects typically diminish after 6-8 hours. Peak concentration (Tmax) is reached at approximately 2 hours.
25 mg — capsule (hydroxyzine pamoate)
Standard starting dose for anxiety; also used for allergic pruritus
50 mg — capsule (hydroxyzine pamoate)
Higher-dose capsule for anxiety; often used at bedtime for sleep or sedation
25 mg/5 mL — oral suspension (hydroxyzine pamoate)
Liquid formulation; used for pediatric patients or those with swallowing difficulties
10 mg — tablet (hydroxyzine HCl)
Lower-dose HCl tablet; useful for children or those requiring smaller doses
25 mg — tablet (hydroxyzine HCl)
Standard HCl tablet; widely available and often more accessible than pamoate capsules
50 mg — tablet (hydroxyzine HCl)
Higher-dose HCl tablet for anxiety or sedation
Vistaril availability is moderately challenging in 2026. Pfizer has stopped marketing brand-name Vistaril, and the American Society of Health-System Pharmacists (ASHP) has maintained an active shortage bulletin for hydroxyzine pamoate capsules since March 2019. Generic manufacturers including Amneal, Teva, Sandoz, and Chartwell continue to produce the drug, but distribution is uneven — some pharmacies carry it consistently while others don't stock it at all.
Hydroxyzine HCl tablets (a clinically equivalent formulation) are generally more widely available and not subject to the same shortage issues. If your prescription is for hydroxyzine pamoate and you're having trouble finding it, ask your prescriber whether switching to hydroxyzine HCl tablets is appropriate.

Because hydroxyzine (Vistaril) is not a controlled substance, it can be prescribed by any licensed healthcare provider with prescribing authority. There are no special DEA requirements beyond a standard prescribing license. This means a wide range of providers can prescribe it, making it more accessible than controlled anxiolytics.
Providers who commonly prescribe Vistaril (hydroxyzine) include:
Primary care physicians (family medicine, internal medicine)
Psychiatrists
Nurse practitioners (NPs)
Physician assistants (PAs)
Allergists and dermatologists
Pediatricians
Anesthesiologists and procedural medicine providers (for preoperative sedation)
Telehealth availability: Because hydroxyzine is not a controlled substance, it can be prescribed through telehealth platforms in all 50 states without an in-person visit requirement. Many patients obtain their hydroxyzine prescription through telehealth, often with same-day prescribing.
No. Vistaril (hydroxyzine) is not a controlled substance under the Controlled Substances Act. It is not scheduled by the DEA and does not carry the prescribing restrictions that apply to benzodiazepines (Schedule IV) or opioids (Schedule II/III).
Hydroxyzine requires a prescription but can be prescribed by a wide range of providers — including primary care physicians, nurse practitioners, physician assistants, psychiatrists, and allergists — without any special DEA registration beyond a standard prescribing license. Prescriptions can be filled via telehealth, and refills are not subject to the same federal limitations that apply to controlled substances.
This non-controlled status is one reason hydroxyzine is frequently prescribed as an alternative to benzodiazepines for patients with anxiety who have a history of substance use disorder or for whom providers wish to avoid Schedule IV prescribing.
Most side effects of Vistaril are mild and often improve with continued use:
Drowsiness (most common; usually transient)
Dry mouth
Headache
Dizziness or lightheadedness
Blurred vision
QT prolongation / Torsade de Pointes (dangerous heart arrhythmia — seek emergency care for fainting, irregular heartbeat)
Acute Generalized Exanthematous Pustulosis (AGEP) — rare, severe skin reaction with fever and pus-filled pustules; stop medication immediately
Seizures or tremors (usually at doses much higher than recommended)
Severe allergic reaction (anaphylaxis) — call 911 for difficulty breathing or facial swelling
Hallucinations (reported in post-marketing experience)

Buspirone (Buspar)
Non-controlled, non-sedating anxiolytic for generalized anxiety. Requires regular dosing (not as-needed); takes 2-4 weeks for full effect. Good long-term alternative to hydroxyzine for daily anxiety management.
Cetirizine (Zyrtec)
Second-generation antihistamine; OTC, once-daily, less sedating than hydroxyzine. Ideal substitute for allergic itching and hives. Note: cetirizine is a metabolite of hydroxyzine; avoid if patient has had hypersensitivity reaction to hydroxyzine.
Sertraline (Zoloft)
SSRI antidepressant; first-line for generalized anxiety disorder and social anxiety. Takes 4-6 weeks to reach full effect. Non-sedating, non-controlled, widely available as generic.
Lorazepam (Ativan)
Benzodiazepine; fast-acting for acute anxiety and procedural sedation. Schedule IV controlled substance with dependence risk. Typically used for short-term or situational needs rather than ongoing daily therapy.
Diphenhydramine (Benadryl)
First-generation antihistamine; OTC, sedating. Similar mechanism to hydroxyzine. Available OTC for allergy relief and sleep, though not FDA-approved for anxiety. Not recommended for elderly patients.

Opioid pain medications (oxycodone, morphine, hydrocodone)
majorHydroxyzine potentiates opioid-induced sedation. CNS depressant doses should be reduced when combined. Risk of respiratory depression.
Benzodiazepines (alprazolam, lorazepam, diazepam)
majorSignificantly enhanced sedation. If combined, benzodiazepine doses should be reduced. Avoid combination without medical supervision.
QT-prolonging antiarrhythmics (amiodarone, sotalol, quinidine)
majorAdditive QT prolongation; risk of Torsade de Pointes. Caution or avoidance required.
QT-prolonging antibiotics (azithromycin, clarithromycin, erythromycin)
majorAdditive QT prolongation risk. Inform prescriber you take hydroxyzine when an antibiotic is considered.
Alcohol
majorSignificantly worsens sedation and impairment. Avoid alcohol entirely while taking hydroxyzine.
Citalopram/escitalopram (Celexa/Lexapro)
moderateBoth hydroxyzine and citalopram can prolong QT interval; additive risk at higher antidepressant doses.
Anticholinergic drugs (tricyclic antidepressants, bladder medications)
moderateAdditive anticholinergic effects: increased dry mouth, urinary retention, constipation, confusion.
Cetirizine (Zyrtec) / Levocetirizine (Xyzal)
moderateCetirizine is a metabolite of hydroxyzine; cross-sensitivity possible. Avoid in patients who have had hypersensitivity reaction to hydroxyzine.
Vistaril (hydroxyzine) is a versatile, affordable, and non-controlled medication with a long track record in the treatment of anxiety, allergic itching, and preoperative sedation. Its non-controlled status makes it easier to prescribe and access than benzodiazepines, and its generic forms are among the most affordable prescription medications available.
The main challenge in 2026 is availability: Pfizer no longer markets brand-name Vistaril, and ASHP maintains an active shortage bulletin for hydroxyzine pamoate capsules. However, multiple generic manufacturers continue to produce it, and the clinically equivalent hydroxyzine HCl tablets are broadly available. Patients and providers can work around availability issues by asking for the HCl formulation, using discount programs like GoodRx, and leveraging tools to locate in-stock pharmacies.
