Had a margarita 6 days before rhinoplasty - should I tell my doctor?

Alcohol is certainly a blood thinner, however, blood levels of alcohol are nearly down to zero in 48 hours or less. I wouldn't worry about it. Hope this helps. Sincerely, Dr. Joseph

Hello! Thank you for your question.
As far as I can understand from your question you should definitely inform your doctor about this information, please do not hide important details from your doctor as you will be anesthetized.
Best Regards!

Always disclose all medications and other substances taken to your surgeon and anesthetists - this is for your own safety. They need to know all of this information to safely take care of you and achieve the best result. Alcohol can increase your propensity to bleed during surgery which is why it is often recommended to abstain from it leading up to surgery. I recommend disclosing this to your surgeon and allow them to decide if it is significant enough to cancel surgery. If they do, remember it is for your own safety.
