A drink or two is unlikely to cause problems with a normal dose of ibuprofen (Nurofen) or paracetamol (Panadol) in healthy adults. Codeine products such as Nurofen Plus, Panadeine and co-codamol are different: alcohol adds to their drowsiness and can slow breathing, so it’s best avoided. Heavy drinking makes every painkiller riskier.

The short answer
| Painkiller | Occasional drink (1–2) | Heavy drinking / binge | Main concern |
|---|---|---|---|
| Ibuprofen (Nurofen, Advil) | Generally OK with food | Avoid | Stomach irritation and bleeding; dehydration and kidneys |
| Paracetamol (Panadol, Tylenol) | OK at normal doses | Lower dose; ask a pharmacist | Liver: chronic heavy use depletes the liver’s protective glutathione |
| Aspirin (pain dose) | Use caution | Avoid | Stomach bleeding |
| Naproxen, diclofenac | Generally OK with food | Avoid | Stomach bleeding |
| Nurofen Plus (ibuprofen + codeine) | Avoid | Avoid | Sedation, slowed breathing, plus stomach risk |
| Panadeine, co-codamol (paracetamol + codeine) | Avoid | Avoid | Sedation, breathing, liver |
| Tramadol, oxycodone (Endone) | Avoid | Avoid | Sedation, breathing, overdose |
Both alcohol and ibuprofen irritate the stomach lining, and together they increase the chance of gastritis and bleeding. Alcohol also dehydrates you, and ibuprofen reduces blood flow to the kidneys, which is a poor mix after a big night or during gastro. If you take ibuprofen after drinking, use a single normal dose with food and water, and avoid it if you have vomited a lot. See which ibuprofen is easiest on the stomach.
The NHS says you can drink alcohol while taking paracetamol at normal doses, but it may not be suitable for people who are dependent on alcohol or binge drink. Long-term heavy drinking increases the liver’s production of a toxic paracetamol by-product and reduces the glutathione that neutralises it, so people who drink heavily, are malnourished or have liver disease may need a lower maximum (for example 2–3 g a day) on advice from a doctor or pharmacist. Never take extra doses to “get ahead of” a hangover.
Codeine is an opioid. With alcohol, the sedative effects multiply: drowsiness, poor coordination and, in larger amounts, slowed breathing. The NHS advises not to drink while taking co-codamol until you know how it affects you, and many pharmacists advise avoiding alcohol entirely. In Australia all codeine products are prescription-only; in the UK low-dose codeine combinations are pharmacy medicines limited to 3 days because of dependence risk. See Endone or codeine with Nurofen.
Get help if someone who has been drinking and taking painkillers is very drowsy, confused, vomiting repeatedly or breathing slowly. If you’ve taken more paracetamol than the label allows, contact a poisons information centre (Australia 13 11 26, US 1-800-222-1222) or NHS 111 straight away, even without symptoms.
There is no fixed waiting time. For a single normal dose after moderate drinking, take it with food and water. After heavy drinking or vomiting, wait until you are rehydrated and eating, or choose paracetamol at a normal dose.
It’s best not to. The codeine in Nurofen Plus adds to alcohol’s sedation, and the ibuprofen adds to its stomach irritation.
A normal dose is fine for most people. People who drink heavily on a regular basis should ask a pharmacist about a lower maximum dose.
Most antibiotics (amoxicillin, doxycycline) don’t interact with moderate alcohol, but metronidazole and tinidazole do. The painkiller rules above still apply.
