How Long After an Ablation Can You Drink Alcohol?

Can you drink alcohol after a cardiac ablation?

Ask the team that did your ablation before you drink again. There is no single official waiting time, but the NHLBI (part of the NIH) gives three facts that matter:

• The risk that atrial fibrillation comes back is highest in the first few weeks after the procedure.
• Alcohol in large amounts, especially binge drinking, raises the risk of atrial fibrillation.
• Even modest amounts of alcohol can trigger atrial fibrillation in some people.

The NHLBI’s lifestyle advice for atrial fibrillation is to limit or avoid alcohol or stimulants that may increase your heart rate.

What research is checking now

A clinical trial registered on ClinicalTrials.gov (NCT05510167) is comparing patients who stop drinking or have no more than 2 drinks a week after ablation with patients who keep their usual drinking habit, to see how it affects the return of the arrhythmia, quality of life and thinking. It is still recruiting, with completion estimated for 2027.

Practical steps

• Follow your discharge instructions on medicines, especially blood thinners, and ask whether alcohol is allowed with them.
• If you do drink later, count it in standard drinks: one 12 oz beer at about 5%, one 5 oz glass of wine at about 12% or 1.5 oz of 40% spirits is one US standard drink (NIAAA). Our standard drink calculator does the maths.
• Contact your care team, or emergency services, about any warning symptoms they told you to watch for after the procedure.
