Drinking alcohol while taking cephalexin is generally not recommended, although it does not usually negate the antibiotic’s effectiveness. The main considerations are that alcohol can increase certain side effects like nausea, stomach upset, and dizziness, and may slow recovery from an infection in some people. If alcohol is consumed, it’s typically advised to do so in moderation and not during the course of antibiotics, or at least wait until you have completed the prescribed course. Key points to consider:
- Side effects: Nausea, vomiting, and abdominal discomfort may be worsened by alcohol during cephalexin treatment.
- Interaction risk: There is no well-established dangerous interaction, but individual responses vary, especially if there are liver concerns or if multiple medications are involved.
- Precautions: If you have a history of alcohol use disorder, liver disease, or are taking other drugs, consult a healthcare provider before drinking.
What to do next:
- If you’re currently on cephalexin, consider avoiding alcohol for the duration of the antibiotic course to minimize GI upset and ensure the best possible recovery.
- If you’ve already taken cephalexin and are considering a drink, monitor how you feel for the next 24–48 hours for any unusual symptoms, and contact a clinician if symptoms worsen.
- For personalized advice, share your specific dose, infection type, liver health, and any other medications with your healthcare provider.
