Can you drink alcohol while taking Ceftazidime and Avibactam Injection?
Last updated September 7, 2026.
**You should avoid alcohol while receiving ceftazidime and avibactam injection, although a direct alcohol interaction is not established.** Alcohol can worsen nausea and dizziness while you are being treated. If you receive this antibiotic for an abdominal infection, your treatment includes metronidazole, which carries a specific alcohol warning. Avoid alcohol throughout metronidazole treatment and for at least 3 days after your last dose, following US medication guidance. Ask your treating clinician or pharmacist to review your other medicines before you drink, and keep your infusions on schedule.
What to do
- **Choose alcohol-free drinks:** Avoid alcohol while you are unwell and receiving treatment.
- **Check for metronidazole:** If you receive it, avoid alcohol during treatment and for at least 3 days afterward.
- **Review your medicines:** Ask your pharmacist to check your full medication list for alcohol interactions.
- **Keep your treatment schedule:** Do not skip or delay an infusion so you can drink.
- **Report symptoms:** Contact your care team if you develop persistent vomiting or worsening dizziness.
