Diazepam (Valium) & Alcohol: Are They Safe to Mix? | Effects, Withdrawal

Anxiety can be an oppressive force in your life. It’s more than experiencing a little nausea before public speaking or nervousness before a test. Anxiety can manifest because of triggers or for no discernible reason at all. Imagine feeling fear or anxiety as if there were a snake in your room but, even when the threat is gone, the panic doesn’t go away. Understandably, those that suffer from extreme anxiety attacks turn to medication to lead normal lives. The problem comes when either the drug is taken in excess or it is mixed with a different substance.

It can be debilitating when anxiety stops you from doing the things you want to do in your life. For many, anti-anxiety drugs can be extremely helpful in curbing the effects of an anxiety disorder. Medications like valium and other benzodiazepines can become a regular part of life. When that happens, it may overlap with other normal parts of life like parties and events that involve drinking. However, Valium and alcohol may not interact well with one another.

dont let addiction win


Valium is the brand name for a drug called diazepam, which is a member of the benzodiazepine (benzos) family. Benzos like diazepam typically cause calming effects that doctors and psychologists use to treat anxiety, panic disorders, muscle spasms, seizures, and insomnia. It can also be used to treat withdrawal symptoms caused by dependence on alcohol and benzodiazepines.

Valium is a long-acting drug, when taken by mouth, and can take up to 40 minutes before taking effect. It’s quickly distributed throughout the body and passes the blood-brain barrier with relative ease.

Valium is safe for most adults and may have very minimal side effects for the most part. Some may experience drowsiness, confusion, or impaired motor functions. It can be more dangerous in older adults, potentially causing amnesia, ataxia, and increased risk of fall because of reduced balance. Benzos also have a slight chance of causing paradoxical reactions, which means they may cause depression, anxiety, or panic in a small percentage of users.

However, the threat of these adverse effects grows when users mix Valium with other depressants like alcohol and the interaction that follows. It can affect the personality and health of the user in an adverse way.


For the most part, you may not realize the danger of what you’re doing. If you get anxious at social functions, you may instinctively take a Valium to help you get through the party. However, social engagements are also a typical setting for alcohol, another social lubricant. Because it may take up to forty minutes for Valium to take effect, you may be able to get to a party and have a drink before you even begin to feel its effects. Many mixers may take Valium and alcohol accidentally, not knowing the risks.

However, some users mix the two substances to take advantage of specific effects. Valium can cause a feeling of deep relaxation or euphoria and users sometimes try to enhance those effects by adding alcohol to the mix. When mixed, diazepam and alcohol may cause an enhanced buzz. Users describe the experience as more relaxing than an alcohol or benzo buzz on their own. However, it also may strengthen other side effects.


Because Valium works on the central nervous system to calm overactive electrical impulses in the brain, it reacts poorly with depressants like alcohol, which also suppress nervous system activity. When mixed, alcohol can amplify Valium’s effects. While that may mean a better buzz or a mild high, it can also mean more extreme tranquilizing effects.

One of the most common side effects of benzodiazepines is drowsiness. When users mix diazepam with alcohol, this effect can intensify to the point of falling asleep or poor coordination. With high amounts of one or both in the combination, users may experience a blackout, a drug-induced state in which short and long term memory creation is blocked. Other side effects include:

  • Lack of coordination
  • Dizziness
  • Alcohol poisoning
  • Loss of consciousness
  • Shallow breathing
  • Overdose
  • Liver damage

Scientists have studied the loss of motor control and how it can affect your ability to drive. Even with small amounts of one or both substances, it made a difference. Separately, the small amounts of Valium and alcohol didn’t make a significant impact at all. However, when they were combined, driving performance suffered noticeably. Users who would usually feel comfortable driving after taking Valium would be more likely to get into a crash if introducing alcohol into their system.

Benzodiazepines have a mild cardiovascular effect that can lead to hypotension in some users. However, when alcohol is also present, it can lead to a “synergistic effect” on blood pressure, meaning that the drugs work together to intensify the effect. In some cases, diazepam can cause tachycardia or an abnormal heart rate.


Valium and other benzos carry some risk of dependence and addiction. The risk is higher with heavier doses and extended use. However, it may also be increased when mixed with other substances. With the drugs working together, users can experience palpable effects, which play on the reward center more intensely.

Plus, if an addiction already exists, a person may be more likely to abuse benzos as well. If a person has tendencies toward alcoholism, they should avoid using Valium or other benzos. Studies show that people with other addictions are significantly more likely to abuse benzos than the general population.


In some circumstances, benzos like Valium can lead to serious medical emergencies like coma, hypotension, and overdose. Benzodiazepines can cause overdoses on their own. However, with medical attention, they typically aren’t fatal. However, benzos accounted for around 9,000 overdose deaths in 2015. Many of these are instances of benzos being mixed with other depressants like alcohol. This can be attributed to the fact that alcohol abuse can be deadly on its own, making the withdrawal from Valium and alcohol equally dangerous without medical supervision. The following symptoms can be signs of a diazepam overdose with alcohol:

  • Slow breathing
  • Slow heart rate
  • Hypotension (low heart rate)
  • Nausea
  • Loss of coordination
  • Coma
  • Loss of consciousness

If you experience any of these symptoms after having mixed Valium and alcohol, call emergency services immediately. If you are stuck in a pattern of benzodiazepine abuse, there is a way out. With a thorough and medically-supervised detox process and proper followup treatment methods, you can find healing and freedom from addiction at a treatment center.
