Will bactroban (mupirocin) lessen an infected wound?

Maybe, maybe: It may help some large, superficial wounds, but won't do much for deep wounds. It does well to treat very superficial skin infections such as impetigo but has not been shown to do much else. In my limited experience, it is overprescribed/used. I don't recommend using in deep wound, which if infected, needs oral/iv antibiotics and wound care. If u are concerned, consult doc. Good luck.

Superfast healing: The real question is what not to do that slows down healing. Avoid using alcohol, peroxide, hibiclens, betadine, and bleach solutions. Inflammation ( red, hot, swollen, tender) is important to healing so anti-inflammatories (motrin, advil) are bad. Cover the area with a clean dressing changed every other day and protected from trauma. Antibiotics do not help healing unless it is truly infected.
