Can I mix alcohol and painkillers while taking acetaminophen for a bad cold?

Short answer

Why people ask this

When you have a bad cold, you might be using acetaminophen to control fever and aches and still wonder if a drink is okay. People also stack multiple cold remedies and painkillers, which can blur what’s safe with alcohol. The overlap of acetaminophen in many cold/flu combo products, nighttime formulas that cause drowsiness, and the dehydration that comes with fever makes alcohol riskier. Add in the temptation to take ibuprofen or naproxen on top of acetaminophen, and the safety picture gets complicated.

When it might be safe

There are no commonly accepted situations where this is considered safe.

When it is not safe

• Alcohol plus acetaminophen raises liver toxicity risk, especially during a bad cold when you may be febrile and dehydrated.
• Many cold/flu combo products already contain acetaminophen—drinking on top of them increases the chance of accidental overdose.
• Adding an NSAID painkiller (ibuprofen/naproxen) while drinking increases stomach bleeding risk, particularly if you’re sick.
• Nighttime cold medicines with sedating antihistamines and alcohol can cause dangerous drowsiness and impaired breathing.
• Some cough syrups contain alcohol, further stacking alcohol exposure without realizing it.

Possible risks

• Acute liver injury or hepatitis from alcohol–acetaminophen interaction and dose stacking.
• Severe drowsiness, confusion, and slowed breathing from alcohol plus sedating cold formulas.
• Stomach irritation, ulcers, or bleeding if NSAIDs are used with alcohol.
• Dehydration and worsened recovery from mixing alcohol with fever and poor fluid intake.
• Medication errors from overlapping ingredients in cold/flu products.

Safer alternatives

• Skip alcohol until at least 24–48 hours after your last acetaminophen dose and when fever and dehydration have resolved.
• Use non-alcoholic comfort options: warm tea with honey, soup, throat lozenges, saline nasal spray, humidifier, and rest.
• Stick to single-ingredient products and track total acetaminophen—stay at or under 3,000 mg/day (≤2,000 mg/day if you drink regularly or have liver concerns).
• If additional pain relief is needed, use either acetaminophen alone as directed or, if appropriate, an NSAID alone—but avoid alcohol with either and take NSAIDs with food.
• Hydrate well and space doses properly (at least 6 hours apart for standard acetaminophen) to reduce strain on the liver during your cold.

Bottom line

While you’re treating a bad cold with acetaminophen, don’t mix in alcohol or other painkillers. It raises the risk of liver damage, dangerous sedation, and bleeding—especially with combo cold/flu products.
