Some patients can be cured with no lifetime sequelae but that is very, very rare. Most patient will lose a limb, or need a skin graft or have other life long side effects even after the initial infection resolves. There is not one pill that everyone who has necrotizing fasciitis can take and recover. Rather, the patients must be treated with antibiotics that their bacteria is sensitive to. This is made more difficult because as the infection progresses there are areas of infection that do not have good blood supply-the blood carries the antibiotic to the infection.
