Smoking cessation. How far before surgery do I have to be done with chantix?

Every surgeon has a different personal feeling about this. The less you smoke the better you will heal. Chantix (varenicline) does have some heart related side effects that you should discuss with your anesthesia provider.

Thank you for your question.  Ideally, any surgeon would prefer that you cease smoking as soon as possible as smoking increases the risk associated with surgery, complications, infection, delayed wound healing, increased bleeding, etc.  At the very least, it is preffered that you cease smoking at least two weeks prior to surgery and that your remain free of smoking and the use of nicotine for a minimum of 3-4 weeks after surgery.Best regards,Dr. Lane F.

Nicotene causes constriction of blood vessels slowing the blood and oxygen delivery to organs, skin and soft tissues.  With many surgeries, this reduction in blood flow can compromise wound healing and result in serious and potentially catastrophic complications.  Although a single cigarette can have detrimental effects for up to one year, most surgeons recommend smoking cessation at least one month prior to surgery and usually continuing for at least one month after surgery.
