CO2 Laser & Rhinoplasty: Herpes Simplex Virus 1 (Oral Herpes)- Should I take an anti viral drug as a precaution before surgery?

Lasering around the mouth could re-activate the herpes eruption. And if it found its way onto the lasered areas, serious infection and scarring could result. So yes, it is prudent to take antiviral medication, starting at least one day before and then after your procedure.

CO2 laser treatment can definitely activate on outbreak of herpes and an antiviral should be taken beforehand prophylactically.  You should discuss this with your surgeon, as many surgeons would normally routinely give this medication for that procedure.   

We prescribe anti-viral medication for all patients who have a history of herpes prior to any surgery. This should be part of your pre-operative medications.
