Can you drink alcohol while taking Augmentin?
A drink or two is usually fine with Augmentin — unlike some antibiotics it does not trigger a violent alcohol reaction and alcohol won't stop it working — but drinking can pile onto the same stomach upset the antibiotic already causes, so go easy and skip it if you feel unwell.
Why
Augmentin (amoxicillin with clavulanate, also called co-amoxiclav) is not a disulfiram-reaction antibiotic — unlike metronidazole or tinidazole, it doesn't react with alcohol to cause flushing, a pounding heartbeat, and violent vomiting, and moderate alcohol does not stop it from clearing your infection. The real issue is overlap: Augmentin can already cause nausea, vomiting, and diarrhoea, and alcohol irritates the same stomach and adds to any drowsiness or dizziness, so drinking can make you feel worse rather than undermining the antibiotic. The NHS advice is therefore practical rather than absolute — a drink or two is usually fine for most people, but take each dose with food, go easy, and skip alcohol entirely if you already feel unwell or have liver problems.
What to watch for
Take Augmentin with a meal — the NHS says this reduces nausea and vomiting, and a full stomach also blunts alcohol's stomach irritation. Go easy, and skip alcohol entirely if you're feeling rough; the NHS advises avoiding alcohol when taking medicine or feeling unwell. There is no fixed "wait X hours after a dose" window for co-amoxiclav — that hard rule exists only for metronidazole/tinidazole (avoid during and for 48–72 hours after), so don't assume one applies here. Watch for stacking side effects: worsening diarrhoea, nausea, vomiting, or dizziness (if dizzy, don't drive or cycle). Call a clinician or NHS 111 urgently for signs of an allergic reaction (swollen throat/tongue, widespread itchy rash, trouble breathing), blistering or peeling skin, yellowing of the eyes or skin, dark urine or right-upper-abdomen pain (possible liver problem), or watery/bloody diarrhoea and severe cramps — which can appear during treatment or up to two months after finishing. Anyone with existing liver problems, or who has had jaundice or liver trouble on an antibiotic before, should ask a doctor or pharmacist before drinking at all.
