Dangers of Mixing Ativan and Alcohol

Ativan (lorazepam), a short-acting benzodiazepine, is an anti-anxiety medication that produces heightened effects on the central nervous system when taken with other depressants, including alcohol.

Drinking alcohol and taking Ativan together can contribute to severe drowsiness, respiratory issues, coma and death. In fact, most cases of Ativan overdose occur in combination with alcohol or other substances.

What Is Lorazepam Used For?

Ativan, or lorazepam, is a potent, immediate-duration benzodiazepine.

It belongs to the same family as other anti-anxiety prescription medications, such as Klonopin, Valium and Xanax. Although it may not be as well-known as some of its cousins, it is still a federally controlled substance with a high risk for abuse and addiction.

Benzodiazepine overdose by itself — when not taken in combination with other substances —  is usually not fatal. People who overdose on lorazepam are likely to experience depression but with normal vital signs like breathing and heart rate.

Lorazepam and Alcohol Interactions

As a CNS depressant, Ativan works by slowing brain activity, creating a more relaxed environment for those struggling with anxiety. It is also commonly used for epilepsy and seizure disorders due to its depressant properties.

However, Ativan and other depressants put people at risk for abuse and addiction due to the euphoria it can cause. Lorazepam and other benzos are rarely misused by themselves, and are usually taken with other substances like alcohol to increase its effects.

Both substances work on the same gamma-aminobutyric acid (GABA) receptors in the spinal cord and brain. Since they work on the same cellular targets, the risk of overdose is greatly increased. Overdose on these substances has a high risk for respiratory depression (slowed or stopped breathing).

Can You Drink on Ativan?

No, you should not drink alcohol while taking Ativan or other benzodiazepines. Your doctor will warn you against combining these two substances. No amount of alcohol is safe to drink while using lorazepam.

How Long After Taking Ativan Can You Drink?

Every substance has a half-life, which is the amount of time it takes for the body to eliminate half of the substance. The half-life for lorazepam is 12 hours. Drugs are completely eliminated in five half-lives, so lorazepam will not be removed until 60 hours after the last dose. Therefore, you should wait at least three days after your last dose of lorazepam to drink alcohol.

How Long After Drinking Can You Take Ativan?

The metabolism of alcohol is well understood, but it is also complicated. It takes approximately one hour to metabolize one standard drink of alcohol for most people, but metabolism varies greatly based on weight, total body water, gender, genetics and other factors. Therefore, it would be safest to wait at least 1–2 days after drinking alcohol to take Ativan.

Mixing Ativan and Alcohol: What Can Happen?

Since alcohol and Ativan work on the same GABA receptors in the CNS, combining them will cause the effects of each individual substance to multiply. GABA is the primary neurotransmitter in the central nervous system. Brain cells use a mixture of “go” and “stop” signals to regulate messages, and GABA is the “stop” signal.

Normally, levels of GABA are kept well-controlled. However, when there is not enough, people can suffer from conditions like anxiety and epilepsy (seizure) disorders. Because of this, benzodiazepines have accepted medical use, and it’s the same reason why alcohol withdrawal can cause seizures and death.

Ativan and Alcohol Can Cause Blackouts

Both substances can cause “blackouts” or long periods where you have no memory. Combining these substances can cause minutes or hours where you “black out’ and have no memory of events. You are at a very high risk of accidental injury and death during this time.

Ativan and Alcohol Can Increase Your Risk of Injury

When combining these two substances, your body is faced with several environmental threats. While alcohol is prone to make you tired, light-headed and drowsy, you are also confronted with Ativan’s effects: concentration issues, movement and coordination difficulty, and delayed physical reactions. The side effects of this combination can put you at risk for accidents and loss of consciousness.

A study in 2005 found that levels of alcohol and benzodiazepines were significantly higher in patients who received treatment for violent accidents versus other types of accidents.

Ativan and Alcohol Can Slow and Stop Your Breathing

When these two substances are mixed, your brain receives signals to shut down certain body functions, including breathing. So, when taking Ativan with alcohol, your body’s oxygen can decrease, which is a primary risk factor for overdose death. Another potential cause of death is inhaling vomit into the airway while unconscious, causing suffocation.

Ativan and Alcohol Can Slow Your Heart

Having healthy blood pressure is crucial to your heart’s functionalities. However, when mixing Ativan and alcohol, your body can experience hypotension or bradycardia. Hypotension is when there is not enough pressure in your blood vessels to provide oxygen to the body, while bradycardia is when the heart is not beating fast enough, putting organs at risk of decreased oxygen.

Long-Term Effects of Ativan and Alcohol

Even if an overdose doesn’t occur, mixing Ativan and alcohol can cause long-term health issues, including development of a substance use disorder and liver damage, among other conditions. An increased likelihood of self-harm is also possible.

Psychological, emotional and behavioral effects include damage to your finances, relationships and other areas of your life. Broken relationships and damage to career or school performance are two possible consequences of Ativan use disorder.

Ativan and Alcohol Overdose

Long-term Ativan and alcohol misuse can put your liver at risk. Alcohol is toxic to the liver, especially in high doses. Ativan is not likely to be toxic to the liver on its own, but it is metabolized by the liver. This means that damage from alcohol can increase blood levels of lorazepam.

When misused over long periods of time, the risk of overdose increases due to liver damage and higher tolerance to the substances, meaning people need more and more of the same drug to produce the same effect. This can contribute to overdose.

Getting Help for Addiction

People who misuse Ativan with alcohol may become dependent on either substance. Taking multiple substances at the same time is referred to as polysubstance abuse.

Not only does polysubstance abuse of alcohol and Ativan come with the risk of addiction, but polysubstance abuse can also increase the likelihood of dangerous or severe withdrawal symptoms during detox. A recent study by The Recovery Village found that people who were detoxing from multiple substances were:

• 2.14 times more likely to experience delirium tremens (DT)
• 2.25 times more likely to experience seizures
• 1.6 times more likely to experience hallucinations
