Impetigo can look similar to other skin conditions. There is no clear evidence-based preference among the different classes of oral antibiotics. Comparison studies also show no significant difference in cure rates between topical and oral antibiotics. No macrolide was found to be better than another, but all were found superior to penicillin V potassium; however, because of increasing macrolide resistance, they are no longer a preferred option.
Although cephalosporins may be used, there is no evidence that one generation is better than another. Younger than three months: 30 mg per kg per day. Loading dose of 4 mg per kg for first dose maximum dose of mg , then 4 mg per kg per day in divided doses every 12 hours.
There is no activity against streptococcus. Information from references 12 and The incidence of MRSA-related skin and soft tissue infections was increasing, but more recent studies show it may be declining. Oral clindamycin penetrates skin and skin structures and should be considered if MRSA infection is suspected. Because of an increasing risk of pseudomembranous colitis, clindamycin should be reserved for patients allergic to penicillin, or for infections that fail to respond to other treatments.
Tetracyclines can be used for susceptible MRSA infections, but should be avoided in children younger than eight years. There are some studies on the benefits of nonantibiotic treatments, such as disinfectant soaps, but they lack statistical power. The evidence is insufficient to recommend or dismiss popular herbal treatments for impetigo. Future treatments for impetigo might include minocycline foam Foamix , which has successfully completed phase II trials, and Ozenoxacin, a topical quinolone that has successfully completed phase III clinical trials.
This area seems to merit further study through rigorous clinical trials. Data Sources : A PubMed search was conducted for impetigo-related topics, including clinical reviews, randomized controlled trials, and meta-analyses.
Search terms included impetigo; impetigo and treatment; retapamulin; fusidic acid; impetigo and MRSA; natural and herbal treatments for impetigo; minocycline foam Foamix ; Ozenoxacin; antibiotic resistance and impetigo; and topical and systemic treatments for impetigo.

It's important to make sure that your child takes the medicine as prescribed. Otherwise, a deeper and more serious skin infection could develop.
While the infection is healing, gently wash the skin with clean gauze and antiseptic soap every day. Soak any areas of crusted skin with warm soapy water to help remove the layers of crust you don't have to remove all of it. To keep impetigo from spreading to other parts of the body, the doctor or nurse will probably recommend covering infected areas with gauze and tape or a loose plastic bandage.
Keep your child's fingernails short and clean to prevent scratching that could lead to a worse infection. Keeping skin clean can help prevent impetigo. Kids should wash their hands well and often and take baths or showers regularly.
Pay special attention to skin injuries cuts, scrapes, bug bites, etc. Keep these areas clean and covered. Anyone in your family with impetigo should keep their fingernails cut short and the impetigo sores covered with gauze and tape. To prevent impetigo from spreading among family members, make sure everyone uses their own clothing, sheets, razors, soaps, and towels. You might be exposed to the bacteria that cause impetigo when you come into contact with the sores of someone who's infected or with items they've touched — such as clothing, bed linen, towels and even toys.
Impetigo typically isn't dangerous. And the sores in mild forms of the infection generally heal without scarring. Keeping skin clean is the best way to keep it healthy. It's important to wash cuts, scrapes, insect bites and other wounds right away. Mayo Clinic does not endorse companies or products.
