Every surgeon is going to have a different opinion on this. There is no textbook or certain answer to this. I myself would advise a patient of mine to wait two months. That said, the only opinion that matters is the surgeon who performs your procedure. Make sure you ask him/her.Ways to reduce the infection risk would be to thoroughly cleanse the nipple with a strong antibacterial soap such as Hibiclens. I would do this tonight before and the morning of. As well, right prior to piercing, wiping the nipple down with alcohol. I would also give one dose of oral antibiotics prior.Most importantly, is to be vigilant after the piercing for any signs of redness or infection whatsoever, and to keep in close contact with your surgeon should there be any change whatsoever.
