Mixing Hydrocodone and Alcohol

Hydrocodone is a prescription opioid medication that’s prescribed to treat relatively minor pain, such as experienced as a result of oral/dental procedures or osteoarthritis.1 Hydrocodone is the most frequently prescribed opioid in the United States with more than 83.6 million dispensed in 2017.2 There are many different brand name and generic hydrocodone medications, and most are combination products—the most frequently prescribed combination is hydrocodone and acetaminophen (Vicodin, Lorcet).1,2

Hydrocodone binds to opioid receptors in the body resulting in depression of activity in the central nervous system (CNS) producing analgesia, euphoria, respiratory depression, and a slowdown of the body’s digestive system.2 As with all opioids, hydrocodone is associated with tolerance, dependence, and addiction.1,2 In fact, hydrocodone is the most common opioid used for nonmedical purposes.2

Like other opioid medications, hydrocodone carries with it a risk of overdose. Someone who takes too much hydrocodone will display the opioid overdose triad of loss of consciousness, pinpoint pupils, and respiratory depression.3 When combined with acetaminophen, there’s an additional risk of liver toxicity due to acetaminophen toxicity.3 Symptoms include sweating, general malaise, nausea, and vomiting.3

Mixing hydrocodone with other substances that also depress the central nervous system—such as alcohol, antihistamines, barbiturates, or benzodiazepines—can be potentially life-threatening.1,4 Drinking alcohol while taking hydrocodone intensifies many of drug’s effects resulting in:4

  • Drowsiness and/or dizziness.
  • Slowed or difficulty breathing.
  • Impaired motor control.
  • Unusual behavior.
  • Memory problems.
  • Increased risk for potentially deadly overdose.

A person who overdoses on hydrocodone in combination with alcohol requires immediate medical attention.5 Bystanders should administer naloxone, if available, in an effort to reverse the opioid overdose. In cases of alcohol poisoning in combination with administration of hydrocodone, naloxone will not have the desired effect.5
