Yes — the NHS says you can drink alcohol while taking amoxicillin, since it's a penicillin antibiotic that doesn't react with alcohol, but drink in moderation, finish the full course, and ask your pharmacist if you're unsure.
Amoxicillin is a penicillin-type antibiotic that works by killing or stopping the growth of the bacteria causing an infection; alcohol doesn't interfere with that mechanism, and the NHS states plainly "you can drink alcohol while taking amoxicillin." Unlike metronidazole and tinidazole — the antibiotics the NHS says you must completely avoid alcohol with because of a disulfiram-like reaction (flushing/hot flushes, feeling and being sick, stomach pain, a fast or irregular heartbeat) — amoxicillin carries no such warning, and the FDA-based MedlinePlus label lists no alcohol interaction. The NHS notes that for the most common antibiotics it's unlikely that moderate drinking will cause problems. Heavy drinking is never advisable while you're sick and fighting an infection.
Keep alcohol moderate, not heavy — being unwell plus a hangover slows recovery, and dehydration is unhelpful when fighting infection. Amoxicillin can cause nausea, diarrhea, or stomach upset (taking it with food helps); alcohol can make those worse, so go easy or skip drinking if you're already feeling sick. Note a separate practical point from the NHS: amoxicillin itself does not stop contraception working, but if it makes you vomit or gives you severe/watery diarrhea (or any diarrhea lasting more than 24 hours), the contraceptive pill may not protect you — use backup protection. Always finish the full prescribed course even after you feel better, to prevent the infection returning. Avoid alcohol entirely and call a clinician if you've been told you're taking amoxicillin combined with metronidazole (e.g. some H. pylori or dental regimens), since metronidazole does react badly with alcohol — and check with your pharmacist or doctor if you have liver problems, take other medicines, or are unsure.
