- Hydroxyzine and Alcohol, Risks of Mixing Them and What to Know
Hydroxyzine (sold under brand names such as Vistaril and Atarax) is a prescription antihistamine that many people take for anxiety or itching. Because it is not a benzodiazepine, it is easy to assume a drink will not matter, but alcohol can make its sedating effects noticeably stronger. We wrote this guide, part of our series on mixing alcohol and medication, to explain the interaction plainly so you can talk it through with your prescriber.
Key takeaways
Here are short answers to the questions we hear most often about hydroxyzine and alcohol.
| Question | Quick answer |
|---|---|
| Is it safe to drink on hydroxyzine? | The FDA prescribing information warns that hydroxyzine can increase the effects of alcohol. |
| What is the main risk? | Stronger drowsiness and dizziness, plus a higher risk of overdose. |
| Can I drive after mixing them? | No. Hydroxyzine alone can cause drowsiness, and alcohol adds to the impairment. |
| Who is most at risk? | Older adults, people with heart rhythm problems, and anyone taking other sedating drugs. |
| When is it an emergency? | Call 911 for a seizure, collapse, very slow breathing, or someone who cannot be woken. |
What is hydroxyzine and why is it prescribed?
Hydroxyzine is an antihistamine prescribed to ease anxiety and tension, relieve itching from allergic skin conditions, and provide sedation around surgery. Vistaril is the brand name for hydroxyzine pamoate.
According to the FDA prescribing information, hydroxyzine is used for anxiety, for itching from conditions such as chronic hives and dermatitis, and as a sedative before and after general anesthesia. Prescribers often choose it when they want to treat anxiety without a benzodiazepine. If anxiety is why you take it, our anxiety treatment page explains how we help people manage it in other ways too.
Is it safe to drink on hydroxyzine?
Drinking on hydroxyzine is not a good idea without your prescriber’s guidance. The FDA prescribing information says hydroxyzine can increase the effects of alcohol and advises avoiding other central nervous system depressants.
Hydroxyzine already causes drowsiness for many people, and the label cautions against driving or operating dangerous machinery while taking it. That built in sedation is exactly why alcohol is a concern. The National Institute on Alcohol Abuse and Alcoholism lists Atarax (hydroxyzine) among allergy medicines that can interact with alcohol, with drowsiness, dizziness and an increased risk of overdose as possible reactions.
What happens when hydroxyzine and alcohol mix?
Alcohol and hydroxyzine both slow the brain, so together they can cause heavier drowsiness, dizziness and impaired judgment. The effect can be much stronger than either one alone.
More drowsiness and dizziness. A dose that normally makes you a little sleepy may leave you groggy, unsteady or unable to stay awake after drinking. The label notes that oversedation is the most common sign of a hydroxyzine overdose.
Impaired judgment and coordination. Together, the two can slow your reaction time and make it harder to think clearly. That raises the risk of falls, injuries and car crashes. If you have had alcohol and hydroxyzine, driving is not safe, even if you feel mostly fine.
Confusion in older adults. The FDA prescribing information cautions that sedating drugs may cause confusion and oversedation in older people, and recommends starting at low doses with close observation. The National Institute on Alcohol Abuse and Alcoholism explains that aging also slows how the body breaks down alcohol, so older adults may feel the combination more strongly.
Heart rhythm concerns. The label notes reports of a heart rhythm problem called QT prolongation, mostly in people with other risk factors, and lists a prolonged QT interval as a reason not to take hydroxyzine. Overdose can also affect heart rhythm. If you have any heart condition, make sure your prescriber knows.
Other sedating drugs add up. The label warns that hydroxyzine can strengthen the effects of opioid pain relievers, other pain medicines and barbiturates. Adding alcohol stacks the sedation further. If you also take a benzodiazepine, our guide to Xanax and alcohol explains those added risks.
A time gap does not make it safe. The National Institute on Alcohol Abuse and Alcoholism notes that harmful interactions can occur even when a medication and alcohol are not taken at the same time.
| Mild signs | Emergency signs |
|---|---|
| Feeling sleepier than usual | Cannot be woken up |
| Mild dizziness or lightheadedness | Collapse or fainting |
| Slower reactions and poor focus | Seizure or convulsions |
| Unsteady walking | Very slow, shallow or irregular breathing |
| Mild confusion | Racing or irregular heartbeat with faintness |

What are the warning signs?
Watch for extreme sleepiness, dizziness, confusion, unsteady walking and changes in heartbeat or breathing. These signs suggest the combination is affecting someone more than expected.
- Extreme sleepiness or trouble staying awake
- Dizziness, lightheadedness or feeling faint
- Confusion, disorientation or slurred speech
- Unsteady walking, stumbling or falling
- A racing, pounding or irregular heartbeat
- Slow or shallow breathing
When should you call 911?
Call 911 right away if someone who has combined hydroxyzine and alcohol cannot be woken up, has a seizure, has collapsed, or is breathing very slowly or irregularly. This is especially urgent if other sedating medications or substances were also involved.
Stay with the person until help arrives, and if they are vomiting or unconscious, turn them onto their side to reduce the chance of choking. Let responders know what was taken. If the person is awake and you are unsure whether it is an emergency, call Poison Help at (800) 222-1222 for guidance.
Anxiety and drinking can sometimes go hand in hand with low mood. If you or someone you love is having thoughts of suicide or self harm, call or text the 988 Suicide and Crisis Lifeline at 988.
What should you ask your prescriber?
Ask whether any alcohol is safe for you, how long drowsiness lasts, and whether your heart health or other medications change the picture. Your prescriber and pharmacist can give advice that fits you.
- Is it safe for me to drink any alcohol while taking hydroxyzine?
- How long after a dose does the drowsiness usually last for someone like me?
- Could any of my other medications, including over the counter sleep or allergy products, add to the sedation?
- Do I have any heart rhythm risks that make hydroxyzine or alcohol a bigger concern?
- If I am using alcohol to manage anxiety, what other support would you suggest?
If you have concerns about your medication, please bring them to your prescriber rather than changing how you take it on your own.
Why do people end up mixing the two?
Hydroxyzine is often prescribed to people already struggling with anxiety or restlessness, the same feelings many people try to soothe with a drink. Because it is not a controlled substance, having both can seem harmless.
A glass of wine at the end of a stressful day can feel like a small comfort. There is no shame in wanting relief, and self medicating with alcohol usually starts with good intentions. Over time, though, drinking tends to worsen anxiety and sleep, and it can turn a helpful medication into a risky one. If you notice you are reaching for a drink more often, our alcohol treatment team can help you look at that pattern without judgment.

Frequently asked questions
Is hydroxyzine safer with alcohol than Xanax?
They work differently, but hydroxyzine still adds to alcohol’s sedation, with drowsiness, dizziness and overdose risk listed for this pairing. Neither combination should be treated as safe without your prescriber’s input.
Can I drink the morning after taking hydroxyzine at night?
Interactions can happen even when the two are not taken together, and drowsiness can linger. Ask your prescriber or pharmacist about timing for your dose.
Is Vistaril the same as hydroxyzine?
Yes. Vistaril is a brand of hydroxyzine pamoate, and Atarax is another brand name for hydroxyzine. The alcohol cautions apply to hydroxyzine in general.
Can I drive after taking hydroxyzine and drinking?
No. The label cautions against driving while taking hydroxyzine because of drowsiness, and alcohol makes impairment worse. Arrange another way home.
Does hydroxyzine affect the heart?
Rarely, it has been linked to a heart rhythm problem called QT prolongation, mostly in people with other risk factors. Tell your prescriber about any heart condition before taking it.
