Can I drink alcohol with Amoxicillin?

How Amoxicillin interacts with alcohol

Amoxicillin is a penicillin-class antibiotic cleared mostly by the kidneys. Unlike metronidazole or tinidazole, it does not cause a disulfiram-like reaction with alcohol. Pharmacologically, moderate drinking does not reduce amoxicillin's antibacterial effectiveness or change blood levels meaningfully.

Safety guidance

• Occasional moderate drinking (1–2 standard drinks): safe with amoxicillin for most healthy adults. Antibacterial activity is preserved.
• Heavy drinking: avoid — not because of a direct interaction, but because alcohol weakens the immune response, delays recovery from infection, and worsens dehydration (which itself increases side effects).
• Stomach upset: both alcohol and amoxicillin can cause nausea; combining amplifies that. Take the drug with food.
• Rest matters: fighting an infection needs good sleep and hydration — alcohol undermines both.

When to avoid alcohol completely

• Severe infections requiring full immune function (sepsis, pyelonephritis)
• Concurrent metronidazole, tinidazole, or cefoperazone (disulfiram-like reaction)
• Liver disease (any hepatic co-medications raise concern)
• Pregnancy, breastfeeding
• Signs of dehydration — fever, vomiting, diarrhea

Clinical sources

• FDA label for amoxicillin (Amoxil) — section 7 "Drug Interactions" lists no alcohol interaction.
• EMA SmPC for amoxicillin — no alcohol interaction documented.

Bottom line

Amoxicillin and moderate alcohol don't interact chemically — antibiotic effectiveness is preserved. Heavy drinking hurts your infection recovery through its effects on the immune system, not a direct amoxicillin interaction. A beer or glass of wine with dinner while on amoxicillin is generally fine for healthy adults.
