I took Diazepam and had alcohol. How dangerous is it?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I had about 30 mg of Diazepam and about two to three cups of 15 % ABV liquor. This resulted in my falling asleep shortly.

  1. Would you classify this as a loss of conscience rather than falling asleep?

  2. How dangerous is it?

I have done this a couple of times before and never had any major negative effects.

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

At 24 years old, what you describe, taking about 30 mg of Diazepam together with two to three cups of liquor at 15 % alcohol, is medically very concerning. Diazepam is a Benzodiazepine that depresses the central nervous system (CNS), and alcohol is also a CNS depressant.

When combined, their effects are not just additive but synergistic, meaning they significantly increase the risk of oversedation, respiratory depression, low blood pressure, impaired reflexes, and, in severe cases, coma or death.

What you experienced may have felt like “falling asleep,” but given the high doses, it is more accurate to consider it a form of drug-induced sedation that could progress to loss of consciousness.

The fact that you woke up without major problems does not make it safe; rather, it means you were fortunate this time. Repeated episodes put your brain, breathing, and even your life at risk, especially if done in an uncontrolled environment without medical supervision.

For treatment and safety, it is strongly advised that you do not combine Diazepam with alcohol at all, since the interaction is unpredictable. If Diazepam has been prescribed, only take it in the exact dose and schedule given by your doctor.

If it was not prescribed, stop taking it immediately and seek medical advice about safe alternatives for anxiety, sleep, or the reason you were using it.

If you ever ingest a large amount again and feel unusually drowsy, confused, or have difficulty breathing, this is a medical emergency, and you should seek help immediately.

For long-term health, consider counseling or support for substance use.

I hope this helps.

Thank you.
