Can you drink wine with medication?
Quick answer
Many medications interact dangerously with the alcohol in wine. The riskiest interactions involve blood thinners (bleeding risk), antidepressants (increased sedation), anti-inflammatories (stomach risk), and paracetamol (increased liver toxicity). Always consult your doctor or pharmacist before drinking wine while on any medication.
Detailed answer
The interaction between alcohol and medication is an underestimated public health issue. Ethanol alters the absorption, metabolism, and elimination of many drugs, with potentially serious consequences.
Blood thinners (warfarin, acenocoumarol): alcohol amplifies the anticoagulant effect, significantly increasing bleeding risk. Even a single glass of wine can throw off the INR (International Normalised Ratio). Classified as a 'major' interaction.
Antidepressants: SSRIs (fluoxetine, sertraline) combined with alcohol increase drowsiness and impair judgment. MAOIs (iproniazide) are absolutely contraindicated with red wine, which contains tyramine — risk of potentially fatal hypertensive crisis.
NSAIDs (ibuprofen, aspirin): combining with alcohol irritates the stomach lining and increases the risk of ulcers and digestive bleeding.
Paracetamol (acetaminophen): both alcohol and paracetamol are metabolised by the liver (cytochrome P450). The combination increases production of NAPQI, a hepatotoxic metabolite. Liver damage risk is real even at therapeutic paracetamol doses in regular alcohol consumers.
Antibiotics: contrary to popular belief, most antibiotics don't interact dangerously with alcohol. Notable exceptions are metronidazole and tinidazole (disulfiram-like effect: nausea, vomiting, tachycardia).
Always consult your doctor or pharmacist before drinking wine while on medication. The medication leaflet lists known interactions in the 'Interactions' section.
| Medication | Risk with Wine | Severity | Recommendation |
|---|---|---|---|
| Blood thinners (warfarin) | Increased bleeding | Major | Avoid or consult |
| MAOIs (antidepressants) | Hypertensive crisis | Major | Absolute contraindication |
| Paracetamol | Liver toxicity | Moderate to major | Strictly limit |
| NSAIDs (ibuprofen) | Stomach ulcer | Moderate | Avoid combination |
