Benzos and Alcohol: Why This Combo Is So Dangerous

What Are Benzos?

Benzos (short for benzodiazepines) are prescription drugs used to treat anxiety, insomnia, seizures, and muscle spasms. Common examples include alprazolam (Xanax), diazepam (Valium), lorazepam (Ativan), and clonazepam (Klonopin).

These medications work by calming the brain and body. On their own and under medical supervision, benzos can help manage mental health and physical symptoms. But mixing benzodiazepines and alcohol changes how they behave in the body—and not in a good way.

Can You Mix Benzos and Alcohol?

The short answer is no—you should never mix benzos and alcohol.

Both substances are depressants, meaning they slow down the brain and central nervous system. Taking them together can intensify side effects such as:

• Extreme drowsiness
• Confusion or disorientation
• Slow breathing
• Low heart rate
• Slurred speech
• Loss of coordination

These effects increase the risk of blackouts, injuries, and accidental overdose.

Even using small amounts of both can be risky. The increased risk is even higher if someone is using benzos without a prescription or drinks heavily.

Why Mixing Benzos and Alcohol Is So Risky

1. They Have Similar Effects on the Brain

Both benzos and alcohol target GABA receptors—a part of the brain that controls calmness and sleep. When combined, they double the impact, which can lead to extreme sedation and a dangerous drop in brain activity.

This can quickly affect basic body functions like breathing, heart rate, and consciousness.

2. Respiratory Depression

One of the most serious dangers of benzos and alcohol is respiratory depression. This means your breathing slows down or stops completely. Without enough oxygen, the brain and organs shut down, which can lead to coma or death.

This risk is even higher in people who already have health issues like asthma, heart disease, or sleep apnea.

3. Increased Risk of Overdose

People who mix benzos and alcohol may not feel the effects right away, so they may take more without realizing how impaired they are. This increases the risk of overdose, especially during short-term binge use or long-term substance use.

Symptoms of alcohol and benzo overdose may include:

• Pale, clammy skin
• Slow or shallow breathing
• Blue lips or fingertips
• Unconsciousness
• Inability to wake up
• Vomiting while passed out

If any of these symptoms appear, call help immediately. An overdose from combining alcohol and benzos is a medical emergency.

Short-Term and Long-Term Effects

Short-Term Risks

• Confusion
• Memory loss
• Slowed reaction time
• Impaired judgment
• Increased risk of accidents and injury
• Dangerous behavior, including self-harm

Long-Term Consequences

Over time, mixing benzos and alcohol can damage both mental and physical health. People may develop:

• Substance use disorder
• Chronic anxiety and depression
• Poor liver and heart function
• Difficulty concentrating
• Withdrawal symptoms when not using
• Trouble sleeping without substances

Long-term use also increases the risk of brain damage, worsens health problems, and may lead to permanent dependence.

Why People Mix Alcohol and Benzos

Some people mix alcohol and benzos to enhance the effects, not realizing they’re putting themselves in danger. Others do it unintentionally—for example, drinking without knowing a medication will interact with alcohol.

Those with anxiety, depression, or trauma may use both to self-medicate, but this often leads to worsening symptoms and a higher chance of addiction.

In some cases, people prescribed benzos like Xanax (alprazolam) may be unaware that even a few drinks can make the medication unsafe.

Who’s Most at Risk?

• People with mental health conditions like anxiety or PTSD
• Teens and young adults who experiment with mixing substances
• Individuals with a history of binge drinking
• Those in high-stress environments or with chronic pain
• Anyone with a substance use disorder or prior overdose

Warning Signs to Watch For

If someone is mixing benzos, or combining them with alcohol, these signs may suggest a serious problem:

• Using pills and alcohol to feel “normal” or fall asleep
• Drinking more after taking medication
• Needing larger doses over time
• Hiding use from others
• Mood swings or frequent blackouts
• Feeling sick when not using

Treatment and Recovery Options

Help is available—and recovery is possible. Because alcohol and benzos both cause physical dependence, it’s important to get medical support when stopping either substance.

Treatment often includes:

• Medical detox to safely manage withdrawal
• Counseling or behavioral therapy
• Medication-assisted treatment
• Group support and relapse prevention tools
• Long-term care for mental health and substance use disorder

Trying to quit alone can be dangerous. Sudden withdrawal from benzos or alcohol can cause seizures, hallucinations, or even death. That’s why supervised care is strongly recommended.

Staying Safe: What You Can Do

• Always check medication labels and avoid alcohol if it says not to drink
• Don’t mix benzos with any other depressants, including sleep aids
• Talk to a doctor if you’re struggling with short-term or long-term use
• Seek help for mental health challenges that lead to substance use
• Know the life-threatening risks of combining substances

Support Starts with Awareness

The effects of benzos and alcohol can be subtle at first—but mixing them is never safe. Whether it happens unintentionally or by choice, the combination can quickly turn life-threatening. With overdose cases on the rise, especially from combining substances, understanding the danger is more important than ever.

If you or someone you love is struggling with benzo and alcohol use, don’t wait. Recovery can feel overwhelming, but with the right support, healing is within reach.
