Key takeaways
The effects stack. Alcohol and benzodiazepines both slow the central nervous system; taken together, sedation and breathing suppression can become dangerous fast.
“Just one drink” isn’t a safe bet. Even small amounts of alcohol can amplify benzo effects; guidance for some benzos (e.g., Xanax) warns not to drink at all and to wait several days after stopping before drinking.
Treatment exists—and it works. Co‑use is treatable with medically supervised detox, careful benzo tapering when indicated, and evidence‑based care for alcohol use disorder.
If you’re navigating anxiety, insomnia, or alcohol use, it’s completely understandable to want relief. Benzodiazepines (often called benzos) can be effective when used exactly as prescribed. Alcohol is legal, common, and socially accepted. Yet together, alcohol and benzodiazepines form one of the riskiest combinations in addiction and mental health care. This guide explains why, what to watch for, and how to move forward safely if this mix is on your radar.

What are benzodiazepines?
Benzodiazepines are prescription sedatives used short‑term for conditions like acute anxiety, panic, seizures, and severe insomnia. Common examples include alprazolam (Xanax), lorazepam (Ativan), diazepam (Valium), and clonazepam (Klonopin). They work by enhancing the brain’s GABA system, slowing activity to create a calming effect. Because tolerance and dependence can develop, prescribers typically use the lowest effective dose for the shortest time.
Why combining alcohol and benzodiazepines is so dangerous
Both alcohol and benzos depress the central nervous system. When combined, their effects are additive—sometimes synergistic—which can deepen sedation, impair coordination, and slow breathing (respiratory depression). That’s why the mix is tied to falls, car crashes, blackouts, and even fatal overdoses. Notably, alcohol plays a causal role in roughly 1 in 5 (18.5%) benzodiazepine overdose deaths each year. Older adults face even higher risks because of age‑related changes and polypharmacy.
Short‑term effects you might notice when benzos and alcohol overlap
Extreme drowsiness or dizziness
Slowed reaction times, impaired balance, and unsteady gait
Slurred speech, confusion, and memory gaps/blackouts
Nausea or vomiting
Danger: slowed or shallow breathing (overdose can escalate quickly)
Longer‑term risks (addiction + mental health)
Regularly mixing benzos and alcohol increases the odds of dependence and accidents, and it can worsen mood and cognition over time (memory, attention, decision‑making). People with alcohol use disorder are more than twice as likely to be prescribed benzos—raising the potential for misuse and adverse events if drinking continues.
Is any amount safe?
Short answer: No. Pharmacist‑reviewed guidance warns against combining any benzo with alcohol—even “just one or two drinks”—because the interaction is unpredictable and can intensify sedation and breathing problems. For Xanax (alprazolam) specifically, consumer guidance recommends avoiding alcohol entirely and waiting at least five days after your last dose before drinking, due to how long the drug can linger. Always ask your prescriber for advice tailored to your exact medication and health status.
“But aren’t benzos used in alcohol withdrawal?”
Yes—in medical settings. During supervised detox, certain benzodiazepines (like diazepam or lorazepam) are first‑line treatments to prevent seizures and stabilize dangerous alcohol withdrawal. That controlled, time‑limited use is not a green light to drink while taking benzos on your own. It’s a short‑term safety plan under monitoring, not a long‑term co‑use strategy.
How to spot an emergency (and what to do)
Call 911 immediately if someone has:
Very slow or difficult breathing
Won’t wake up or can’t stay awake
Blue/gray lips or fingertips, or severe confusion
Seizures
Stay with the person, place them on their side if they’re unconscious and breathing, and share what substances were taken. Overdoses are life‑threatening, and mixed sedatives can spiral rapidly.

Safer next steps if alcohol and benzodiazepines are both in the picture
You deserve care that honors your mental health and reduces risk. Here’s a practical path forward:
Talk to your prescriber first
Be open about how much and how often you drink. Your clinician can adjust timing, dose, or consider non‑sedatingoptions for anxiety/insomnia (e.g., SSRIs/SNRIs, CBT‑I/CBT), and help you plan a taper if you’ve been on benzos long‑term.
Use harm‑reduction if you’re not ready to stop yet
While the safest choice is not to mix, small changes can lower immediate risk: avoid other depressants (opioids, sleep meds), don’t use alone, plan a ride, and set conservative limits. If you notice escalating use or memory gaps, that’s a signal to pause and reassess with a pro.
Consider integrated treatment for co‑use
When alcohol use and benzo dependence overlap, comprehensive care helps. That may include medically supervised detox, a gradual benzo taper, and FDA‑approved medications for alcohol use disorder (e.g., naltrexone, acamprosate, disulfiram), alongside therapies and peer support. Your care team will tailor the plan to your mental‑health needs and daily life.
How long after taking a benzo can I drink?
There isn’t a one‑size‑fits‑all window—half‑lives vary by medication and your metabolism. Broad consumer guidance says to avoid alcohol entirely on benzos; for Xanax, wait ~5 days after your last dose before considering a drink (and confirm with your prescriber).
Why do people say mixing causes “blackouts”?
Both alcohol and benzodiazepines impair the brain’s ability to form memories; together, the effect is stronger, increasing the risk of amnesia/blackouts and dangerous decisions you won’t recall.
Are older adults at special risk?
Yes. Age‑related changes, fall risk, and multiple medications make combinations of alcohol and benzodiazepinesparticularly hazardous in older adults. Even typical doses can cause outsized effects.

Frequently Asked Questions About Mixing Alcohol and Benzodiazepines (Benzos & Alcohol)
What happens when you mix benzodiazepines and alcohol?
Mixing benzos and alcohol both depress the central nervous system, causing deep sedation, slowed breathing, memory blackouts, and impaired coordination. This combination dramatically increases the risk of overdose—even after just a small amount—because their effects stack unpredictably.
Is there ever a “safe” amount to mix benzos and alcohol?
No. The consensus from health professionals and pharmacists is that it’s unsafe to combine any amount of alcohol with benzodiazepines because of the unpredictable and potentially fatal effects. Even “just one drink” can amplify sedation and respiratory suppression dangerously.
What are the short-term versus long-term effects of mixing alcohol with benzodiazepines?
Short‑term effects include dizziness, slowed reaction times, confusion, blackouts, and difficulty breathing. Long‑term co‑use can increase risks of organ damage, accelerated dependency, cognitive decline, and worsening mental health issues.
Why do people mix alcohol and benzodiazepines despite the dangers?
Some individuals use benzos to intensify alcohol’s effects or to manage withdrawal, anxiety, or insomnia. Others may inadvertently co-use due to tolerance or self‑medication. Unfortunately, this pattern can lead quickly to dangerous dependency.
How dangerous is combining benzos and alcohol?
Extremely dangerous. Benzodiazepine overdoses alone are rarely fatal—but mixed with alcohol, the risk of coma, respiratory failure, and death increases substantially. This combo also contributes to a higher rate of ED visits and emergency outcomes.
Can benzodiazepines be safely used for alcohol withdrawal?
Yes—but under strict medical supervision only. In treated detox settings, benzos (like diazepam or lorazepam) are often used to manage seizures and withdrawal symptoms. This controlled, short‑term use is very different from recreational mixing.
Are older adults at a greater risk when mixing benzos and alcohol?
Absolutely. Age‑related changes amplify the sedative effects of both substances, increasing risks of memory problems, falls, accidents, and even dementia‑like symptoms. Prescribers often avoid benzos in older adults for these reasons.
