Beer and Methadone

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Beer interacts with whole categories of medication. Methadone falls into 2 of those categories, so it can interact with Beer in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

CNS DEPRESSANTS

1 of 2

Why this applies to Methadone

Methadone falls under CNS DEPRESSANTS — the group Beer interacts with.

Concomitant use may increase sedative and other adverse effects.
Concomitant use of alcohol with CNS depressants can increase sedative and other adverse effects, potentially through inhibition of the metabolism of certain CNS depressants.
Severity Major Likelihood Likely Evidence C

Well-controlled human studies have demonstrated the likely existence of this interaction.

I want to be straight with you about this one: mixing beer with methadone is a genuinely risky combination, not a minor concern. Both alcohol and methadone slow down your brain and your breathing, so putting them together stacks those effects on top of each other. You may feel much more drowsy, dizzy, confused, or foggy than usual, and your coordination can suffer.

The bigger danger is breathing. Methadone already lowers your breathing rate, and alcohol pushes it down further, which can become life-threatening, especially at higher doses or if you drink quickly. Alcohol may also slow how your body clears methadone, letting it build up. Please talk with your pharmacist or doctor before drinking any alcohol while on methadone.

NARCOTIC DRUGS

2 of 2

Methadone also falls under NARCOTIC DRUGS.

Concomitant use of large amounts of alcohol may decrease the metabolism of narcotic drugs.
Concomitant consumption of large amounts of alcohol can decrease the metabolism of narcotic drugs.
Severity Moderate Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: methadone is a strong opioid that your body has to break down and clear. When you drink a lot of beer, the alcohol can slow that breakdown, so methadone may linger longer and build up to higher levels than usual. On top of that, alcohol and methadone both calm down the brain and breathing, so their effects stack.

That combination can mean heavier drowsiness, confusion, slowed breathing, and dangerously low alertness. With methadone this matters a lot, since slowed breathing can become life-threatening. Please don't change anything on your own, but do talk with your pharmacist or doctor about drinking while on methadone so they can keep you safe.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

About Beer

What is Beer?

Beer
  • Social and recreational drinking
  • Relaxation
  • Heart health (popular belief)
  • Bone health (popular belief)
  • Source of antioxidants and B vitamins

Beer is an alcoholic beverage that contains some minerals, B vitamins, and plant compounds from hops and grain, but it is not a health supplement. Any possible benefits come only from light-to-moderate intake, and they are easily outweighed by the well-known harms of alcohol. The safest amount of alcohol for health is none, and beer should be avoided in pregnancy and breastfeeding.

About Methadone

What Is Methadone Used For?

Brand name: Dolophine

Methadone treats severe and persistent pain that requires daily, around-the-clock, long-term opioid treatment and cannot be managed adequately with other options. It is available in several forms for this use, including oral solution, oral tablets, oral concentrate, and injectable forms (intravenous, intramuscular, and subcutaneous). Injectable methadone is not approved for outpatient pain treatment — it is reserved for hospitalized patients unable to take oral medication.

Methadone is also used for the detoxification and maintenance treatment of opioid addiction (dependence on heroin or other morphine-like drugs). Oral forms — including tablets, dispersible tablets (such as Methadose Dispersible and DISKETS), and oral concentrates (such as Methadone Hydrochloride Intensol™, Methadose, and others) — are approved for this use. By law, methadone for opioid addiction treatment must be dispensed only by certified opioid treatment programs. Injectable methadone is not approved for outpatient addiction treatment.
