Interaction report

Wine and Meperidine, Promethazine

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

Why Are There 2 Interactions?

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

Major

CNS DEPRESSANTS

1 of 2

Why this applies to Meperidine, Promethazine

Meperidine, Promethazine falls under CNS DEPRESSANTS — the group Wine 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo medicine packs a real one-two punch on the brain. Meperidine is an opioid pain reliever, and promethazine is a sedating antihistamine. Both already slow you down on their own. Add wine, and you stack a third sedative on top, so the effects pile up rather than cancel out.

What that can look like in real life: heavy drowsiness, dizziness, slurred speech, confusion, trouble staying alert, and in worse cases slowed or shallow breathing. Alcohol can also slow how your body clears these drugs, letting them build up. This is a well-recognized, serious pairing. Please don't change anything on your own, but do talk with your pharmacist or doctor about avoiding alcohol while you're taking it.

NARCOTIC DRUGS

2 of 2

Meperidine, Promethazine 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Mepergan combines two medicines that already slow you down: meperidine, an opioid pain reliever, and promethazine, a sedating antihistamine. Drinking large amounts of wine can slow how your body breaks down the opioid part, letting it build up in your system. On top of that, alcohol, meperidine, and promethazine each calm the brain on their own, so stacking them really piles on.

What that can look like in real life: heavy drowsiness, dizziness, confusion, very slow or shallow breathing, and in serious cases, breathing that becomes dangerous. This is a known concern, so please don't change your medicine on your own. Talk with your pharmacist or doctor about how much alcohol, if any, is safe for you while taking this combination.

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.
