Emergency first: if someone has mixed Ativan and alcohol and shows any of these signs, call 911 now.
- Breathing that is slow, shallow, noisy, or has long pauses
- Blue or gray lips or fingertips, or cold, clammy skin
- You can’t wake them, or they wake briefly and drift straight back off
- Vomiting while very drowsy or barely conscious
- Severe confusion, slurred speech that keeps getting worse, or a seizure
While you wait: roll the person onto their side (the recovery position) with the top knee bent forward and the head tilted slightly back so vomit can drain out of the mouth. Stay with them and watch their breathing. Do not let them “sleep it off,” do not give coffee or a cold shower, and do not try to make them throw up. If they are awake and you are unsure how serious it is, call Poison Control at 1-800-222-1222 (24/7, free). Tell the 911 operator or poison specialist exactly what was taken, how much, and when.
Ativan and alcohol are a common pairing, often without anyone meaning harm: a glass of wine at dinner, then the usual evening dose. But both slow the brain in overlapping ways, and together they can do far more than either one alone. This guide walks through what happens inside your body, hour by hour, when the two meet, what the research numbers show, and what to do if you or someone you love has already mixed them.
Ativan is the brand name for lorazepam, a benzodiazepine prescribed mainly for anxiety. If you’re new to the drug, our overview of common and serious Ativan side effects is a helpful starting point. Here, the focus is narrow: alcohol, and why the pairing earns one of the strongest warnings on the label.
Why Ativan and alcohol multiply each other
Your brain runs on a balance of “go” signals and “slow down” signals. The main slow-down messenger is a chemical called GABA. When GABA attaches to its receptor (the GABA-A receptor) on a nerve cell, it opens a tiny channel that makes that cell less likely to fire. Less firing means calmer thoughts and, at higher levels, sleep.
Lorazepam doesn’t create GABA. It attaches to its own spot on the GABA-A receptor and makes the receptor respond more strongly to the GABA that’s already there.
Alcohol also boosts GABA-A activity, through a different binding spot. On top of that, it dampens glutamate, the brain’s main “go” signal, and affects several other chemical systems. So when lorazepam and alcohol are both present, the slow-down signal is amplified from two directions while the speed-up signal is weakened at the same time. That’s why the combined effect can be greater than you’d predict by simply adding one drink to one pill.
The breathing problem
You don’t decide to breathe while you sleep. A cluster of cells in the brainstem watches carbon dioxide levels in your blood and triggers each breath automatically. Sedatives blunt how sharply those cells respond. One sedative at a normal dose usually leaves enough reserve. Two sedatives stacked together can push breathing slower and shallower, especially during deep sleep, when no one is awake to notice.
The prescribing information for Ativan says that using lorazepam with other central nervous system depressants may cause respiratory depression that can be fatal, and it lists alcohol among those depressants (Ativan prescribing information on DailyMed).
The gag reflex problem
Alcohol irritates the stomach, and heavy drinking often brings nausea and vomiting. Normally, your gag and cough reflexes protect your airway when that happens. Deep sedation dulls those reflexes. A person who is heavily sedated and vomits can inhale stomach contents into the lungs, which is called aspiration. It can cause choking, aspiration pneumonia, or death, which is why the recovery position matters so much.
What the label actually says
The current Ativan label repeats the alcohol warning in several places. In plain terms, it says:
- Your tolerance for alcohol and other sedating drugs will be lower while you take lorazepam.
- Combining lorazepam with alcohol increases the depressant effect on the brain.
- Misuse of benzodiazepines commonly involves alcohol, and that combination is linked to more serious outcomes.
- An overdose of lorazepam taken together with alcohol or opioids may be fatal.
Since 2020, every benzodiazepine also carries a boxed warning, the FDA’s most prominent type. It covers the risks of abuse, misuse, and addiction; physical dependence and withdrawal reactions; and serious harm when benzodiazepines are combined with opioids. In announcing that change in September 2020, the FDA told patients directly not to drink alcohol with benzodiazepines because it raises the risk of serious and life-threatening side effects (FDA Drug Safety Communication, 2020).
What can happen over an evening
Numbers and receptor diagrams can feel abstract. The table below follows a hypothetical evening to show how the risks of Ativan and alcohol can build. Say a person takes their prescribed afternoon dose of lorazepam, then goes out and has several drinks over a few hours. This is an illustration of what can happen, not a prediction of what will happen to any one person.
| Time point | What’s happening inside | What you might notice | Main danger |
|---|---|---|---|
| First drink | Lorazepam is already near its peak level (roughly 2 hours after a tablet). Alcohol starts adding to its effect on GABA-A receptors within minutes. | The drink “hits” faster or harder than usual. Feeling warm, loose, more relaxed than expected. | Underestimating impairment. Deciding to drive. |
| About 1 hour in | Blood alcohol is rising. Both substances are acting on balance, reaction time, and judgment at once. | Unsteady walking, slurred words, slowed reactions, poor judgment about having “one more.” | Falls, head injuries, car crashes, risky decisions. |
| 2–3 hours in | Combined sedation deepens. The brain’s memory-recording system is suppressed by both substances. | Heavy drowsiness. Gaps in memory or a full blackout. Nausea. | Blackouts, vomiting while drowsy, being left alone to “sleep it off.” |
| Overnight | Sleep turns very deep. The brainstem responds less to rising carbon dioxide. Airway muscles relax; snoring or apnea may worsen. | Loud snoring, gasping, long pauses in breathing, hard to rouse. Others may mistake this for ordinary sleep. | Respiratory depression, aspiration of vomit, low oxygen, death. |
| Next morning | Lorazepam has a half-life of about 12 hours, so a good part of the dose is often still active. Alcohol may be mostly cleared, but its after-effects are not. | Grogginess, poor coordination, headache, rebound anxiety, patchy memory of the night. | Impaired driving or work, falls, and taking the next dose on top of leftover sedation. |
Blackouts are not the same as passing out. During a blackout, a person can walk, talk, and even seem fairly normal, yet their brain isn’t storing new memories. Both alcohol and benzodiazepines interfere with memory formation, so the pairing makes blackouts more likely.
The overnight hours are the most dangerous. Many deaths involving sedatives happen during sleep, when breathing slows and nobody is watching. That’s why “let them sleep it off” is such risky advice. If someone has taken both and is hard to wake, treat it as an emergency.
The morning after still counts. Lorazepam lingers. If you’re curious about how long traces stay detectable, our guide on how long Ativan stays in your system covers blood, urine, and hair testing windows in detail.
What the numbers show
The danger of mixing Ativan and alcohol, and benzodiazepines and alcohol in general, isn’t just theoretical. U.S. public health agencies have tracked it in emergency departments and death records. The figures below come straight from the original reports. Some are older, because national tracking of alcohol in benzodiazepine cases hasn’t been repeated in the same form, so each is labeled with its year.
| Finding | Data year(s) | Source |
|---|---|---|
| Alcohol was involved in 27.2% of benzodiazepine drug abuse–related emergency department visits (about 111,000 of 408,000 visits). | 2010 | CDC, MMWR 2014 |
| Alcohol was involved in 21.4% of benzodiazepine-related deaths (324 of 1,512 deaths in 13 states). | 2010 | CDC, MMWR 2014 |
| Alcohol involvement in benzodiazepine ED visits was highest among adults aged 45–54 (31.1%); in benzodiazepine deaths it was highest among people 60 and older (27.7%). | 2010 | CDC, MMWR 2014 |
| Benzodiazepines combined with opioid pain relievers or alcohol were linked to a 24% to 55% higher predicted risk of a more serious ED outcome than benzodiazepines alone. | 2005–2011 | SAMHSA, DAWN report |
| Benzodiazepine-involved overdose deaths rose from 1,298 to 11,537. | 2010 to 2017 | FDA, 2020 |
| Of 8,761 poison control calls about benzodiazepine misuse or abuse, 63% involved more than one substance. | 2017 | FDA, 2020 |
The CDC analysis is especially striking. It concluded that alcohol was a frequent and often overlooked factor in these ED visits and deaths (CDC MMWR, 2014).
SAMHSA’s Drug Abuse Warning Network (DAWN) took a different angle. Across an estimated 943,000 ED visits from 2005 through 2011 that involved benzodiazepines alone or with opioid pain relievers or alcohol, adding either substance raised the chance of a more serious result, such as hospital admission, transfer to intensive care, or death (SAMHSA DAWN report abstract on PubMed).
More recent CDC data highlight a related trend. Among benzodiazepine-involved overdose deaths in 38 states and Washington, D.C., from January 2019 to June 2020, 91.4% also involved opioids (CDC MMWR, 2021). That report didn’t break out alcohol, but it shows how rarely fatal benzodiazepine overdoses involve the benzodiazepine alone.
How long to wait between Ativan and a drink
“How long after Ativan can I drink?” is one of the most searched questions about this drug. The honest answer is that there is no single safe number of hours that applies to everyone, and the label’s guidance is simply not to combine them. Here’s why a universal waiting time doesn’t exist.
Half-life basics. Half-life is the time it takes your body to clear half of a drug from the blood. The Ativan label lists a mean half-life of about 12 hours for lorazepam itself. Clinical references give a typical range of roughly 10 to 20 hours, and the StatPearls review on NCBI Bookshelf lists 14 ± 5 hours (StatPearls: Lorazepam, updated 2024). It usually takes about four to five half-lives for a drug to be mostly cleared. With a 12-hour half-life, that works out to roughly two to two and a half days after a single dose.
Why that math doesn’t settle it. Many people take Ativan two or three times a day, every day. With regular dosing, the drug never drops to zero between doses; it builds up to a steady level. “Waiting a few hours” after the last tablet doesn’t mean the drug has left. On top of that, even a partly cleared dose lowers your alcohol tolerance, and the label notes that tolerance is reduced while you take lorazepam.
Factors that can stretch the timeline
- Older age: Older adults are more sensitive to sedation and unsteadiness, even if lorazepam levels are similar.
- Liver disease: The liver processes lorazepam, and the label urges caution in severe liver impairment.
- Higher or more frequent doses: More drug on board takes longer to clear.
- Other sedating medicines: Opioids, sleep aids, some antihistamines, muscle relaxants, and certain antidepressants all add to the effect.
- Body size, sex, and hydration: These change how high blood alcohol rises from the same drink.
The practical path: If you’d like to drink at all while on Ativan, raise it directly with your prescriber or pharmacist. They know your dose, schedule, other medicines, and health history, and can tell you whether any alcohol is reasonable for you. Never skip or shift a dose on your own to “make room” for drinking; that can trigger rebound anxiety or withdrawal symptoms. Our guide to typical Ativan doses for anxiety explains how prescribers usually structure the daily schedule.
Who is at highest risk
Mixing Ativan and alcohol is risky for anyone, but some people have much less margin for error.
People who also take opioids
The boxed warning on every benzodiazepine singles out opioids: the combination can cause profound sedation, slowed breathing, coma, and death. Opioid pain medicines (like hydrocodone or oxycodone), opioid cough syrups containing codeine, and illicit opioids all count. Adding alcohol creates a triple threat to breathing. Our article on taking gabapentin with hydrocodone explains how stacking sedating drugs on an opioid raises breathing risk, and the same principle applies here.
People with sleep apnea or lung disease
The Ativan label advises caution in people with compromised breathing, such as COPD or sleep apnea, and lists worsening of sleep apnea among reported reactions. Alcohol also relaxes the throat muscles that keep the airway open during sleep. If you already stop breathing briefly during the night, both substances can make those pauses longer and more frequent.
Older adults
The label notes that older or debilitated patients may be more sensitive to sedation, and recommends lower starting doses. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) adds that older people clear alcohol more slowly and are more likely to take several medicines that interact with it, which raises the risk of falls and serious injuries (NIAAA: Harmful Interactions).
People with liver disease
Alcohol is hard on the liver, and severe liver disease can affect how the brain handles sedatives. The label warns that lorazepam may worsen hepatic encephalopathy, a confusion state caused by liver failure. Interestingly, lorazepam is often a preferred benzodiazepine in people with cirrhosis because it skips the liver’s main drug-processing enzymes, but that choice is made by clinicians who are monitoring the patient, not a sign that drinking on it is safer.
Teens and young adults
The safety and effectiveness of lorazepam tablets haven’t been established in children under 12. Teens and young adults who come across benzodiazepines (sometimes from a family medicine cabinet, sometimes as counterfeit pills) often have little tolerance to either drug and may drink in binges. Counterfeit “benzos” may also contain other potent sedatives or fentanyl.
People with alcohol use disorder
Heavy daily drinkers may feel less drunk than their blood levels suggest, while their breathing reserve is no greater. They’re also at higher risk of benzodiazepine misuse. The label asks prescribers to assess each patient’s risk of abuse, misuse, and addiction before and during treatment, and honest conversation about drinking is a key part of that.
Wait — isn’t Ativan used for alcohol withdrawal?
Yes, and this confuses a lot of people. Lorazepam is one of the most frequently used drugs to treat alcohol withdrawal. So how can it be both a treatment for alcohol problems and dangerous with alcohol?
The answer comes down to timing and supervision. When someone who drinks heavily every day suddenly stops, the brain, which has adapted to constant alcohol, swings into overdrive. Withdrawal can bring shaking, sweating, racing heart, anxiety, hallucinations, seizures, and in severe cases a dangerous state called delirium tremens. Because benzodiazepines act on the same GABA-A system, they can stand in for alcohol and calm that rebound safely.
How medically supervised use works
- Alcohol has stopped. The benzodiazepine is given as alcohol leaves the body, not on top of it.
- Symptoms are scored. Clinicians commonly use a checklist called the CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised) to rate symptoms like tremor, sweating, agitation, and nausea at regular intervals.
- Doses follow the scores. In “symptom-triggered” treatment, medication is given only when scores pass a set threshold. The StatPearls review notes this approach tends to use lower total doses and shorter treatment than fixed schedules.
- Someone is watching. Breathing, alertness, heart rate, and blood pressure are checked. Treatment happens in a hospital, a withdrawal-management unit, or a carefully selected outpatient program.
- It’s short-term and part of a bigger plan. The benzodiazepine is tapered off over days, and the American Society of Addiction Medicine’s 2020 alcohol withdrawal guideline stresses that withdrawal care should connect people to ongoing treatment for alcohol use disorder.
Compare that with combining Ativan and alcohol on a regular prescription: both substances are active at the same time, nobody is scoring symptoms or checking breathing, and the doses aren’t being adjusted to what your body can handle. The drug is the same; the situation is completely different. Never try to manage alcohol withdrawal at home with leftover or borrowed Ativan. Withdrawal seizures and delirium can come on quickly, and unsupervised dosing while alcohol is still in your system risks exactly the overdose this article describes.
Hidden alcohol: where it sneaks in
Avoiding beer, wine, and spirits is the obvious step when you want to keep Ativan and alcohol apart. But alcohol also turns up in products you might not think of as “drinking.” Small amounts rarely cause a dangerous reaction alone, but they add up.
| Source | Why it matters | What to do |
|---|---|---|
| Liquid cough and cold medicines | NIAAA notes some medicines contain up to 10% alcohol, with cough syrups and laxatives among the highest. Some cough syrups also contain codeine or other sedatives. | Check the “inactive ingredients” for alcohol or ethanol. Ask your pharmacist for an alcohol-free option. |
| Nighttime cold and flu liquids | Often combine alcohol with a sedating antihistamine, adding two more depressants. | Choose daytime, alcohol-free products, or ask before taking. |
| Mouthwash | Many brands contain alcohol. Normal rinsing and spitting is not the concern; swallowing it is. | Use an alcohol-free version if you’re worried, and store it away from children. |
| Kombucha | It’s fermented, and alcohol content can rise after bottling. Some kombuchas are sold as alcoholic drinks. | Read the label; avoid “hard” kombucha entirely. |
| “Non-alcoholic” beer and wine | Many can legally contain small amounts of alcohol. | Look for “0.0%” if you want none at all. |
| Cooking and desserts | Cooking burns off some alcohol, but not all, especially in quick sauces, flambés, or no-bake desserts like tiramisu or rum cake. | Ask when eating out; be cautious with liqueur-soaked desserts. |
| Herbal tinctures and extracts | Many tinctures use alcohol as the base. Some herbs, like valerian or kava, are also sedating. | Check labels and run any supplement past your pharmacist. |
A good habit: when you buy any new over-the-counter product, tell the pharmacist you take lorazepam.
Getting help
Sometimes mixing Ativan and alcohol is a one-time mistake. Sometimes it’s a sign that one or both substances have become harder to control. Either way, help is available.
Signs it may be more than a one-off
- Taking Ativan more often or in larger amounts than prescribed, or running out early
- Drinking to boost the effect of the medicine, or taking the medicine to boost the effect of drinking
- Getting prescriptions from more than one doctor, or using pills that weren’t prescribed to you
- Memory gaps, frequent falls, or friends and family voicing concern
- Feeling shaky, anxious, or unwell when you skip a dose or a drink

Don’t stop Ativan suddenly
After a scare, you may want to quit on the spot. Please don’t do it without medical guidance. If you’ve been taking lorazepam regularly, your body has likely adapted to it, and stopping abruptly or cutting down quickly can cause withdrawal reactions that, according to the label, can be life-threatening, including seizures. Stopping alcohol suddenly after heavy daily drinking carries similar risks.
In 2025, a coalition of medical societies led by the American Society of Addiction Medicine released a Joint Clinical Practice Guideline on Benzodiazepine Tapering. It encourages clinicians to plan tapers with the patient, start slowly, adjust the pace based on how the person responds, and arrange a higher level of care when needed. Your prescriber designs and monitors any taper with you. Our guide to Ativan withdrawal symptoms and timeline explains what that process typically looks like.
If you’re weighing other anxiety medicines because of concerns about alcohol, your prescriber can walk you through the options. Our Xanax vs. Ativan comparison can help, though the alcohol warning applies to every benzodiazepine.

Frequently asked questions
Is one drink on Ativan dangerous?
One drink is far less likely to cause a life-threatening reaction than several, but it’s still not considered safe. Even small amounts add to lorazepam’s sedation and slow your reaction time, which matters for driving, stairs, and anything needing coordination. The label says your tolerance for alcohol is reduced while you take lorazepam. People who are older, have sleep apnea, or also take opioids have the least margin. Ask your prescriber what’s right for you.
I already took Ativan and had a few drinks. What should I do?
Stop drinking and don’t take any more lorazepam or other sedating medicines tonight. Don’t drive. Stay with someone who can check on you, and sleep on your side. If you’re unsure whether you’re in danger, call Poison Control at 1-800-222-1222. If you or someone with you notices slow or irregular breathing, blue lips, vomiting while drowsy, or difficulty staying awake, call 911 right away.
Can I take Ativan for a hangover or the anxiety after drinking?
Not without talking to your prescriber. The morning after heavy drinking, some alcohol may still be in your blood, and taking lorazepam then can stack the effects. The anxious, shaky feeling after a night of drinking (sometimes called “hangxiety”) can also be an early sign of alcohol withdrawal in people who drink heavily. If that happens regularly, talk with your doctor.
Is lorazepam and alcohol any different from Ativan and alcohol?
No. Lorazepam is the generic name, and Ativan is a brand name for the same medicine. Generic lorazepam tablets, the brand, and other forms all carry the same alcohol warning. The same goes for other benzodiazepines such as alprazolam (Xanax), diazepam (Valium), and clonazepam (Klonopin).
Medical disclaimer: Healthetive shares this information to help you understand a serious drug-alcohol risk; it is not individual medical advice. Lorazepam is a prescription medicine with real risks, and only someone who knows your full health history can advise you on it. Don’t start, stop, or change any medicine based on what you read here. If you think someone has overdosed, call 911 immediately.
