Impetigo (cont.)

Impetigo Follow-up

Keep the skin clean and dry and avoid any further injury. Use the medication the physician prescribes. If the rash becomes more extensive, becomes more painful, or worsens in any other way, contact a physician or get evaluated in the emergency department.

Impetigo Prevention

Prevent impetigo by avoiding contact with others who have this skin infection. It also helps if to keep skin clean, dry, and avoid scraping or injuring the skin.

Impetigo Prognosis

Impetigo is easy to treat. Complications occur very infrequently. One rare, but potentially serious complication is inflammation of the kidney. This can occur because of a complex immune reaction to the bacteria and is called glomerulonephritis. If someone has blood in their urine, facial or skin swelling, or a rise in blood pressure, he or she should see a physician immediately, since these may be symptoms of kidney involvement.
