A complication of Stevens-Johnson syndrome can be permanent color changes of the skin, according to the Mayo Clinic. When the skin grows back, it sometimes has bumps or abnormal coloring. Some patients also have scarring as a result of the condition.
Other skin problems may include lack of hair growth or nails growing back improperly, the Mayo Clinic reports. A serious skin infection called cellulitis sometimes occurs. Cellulitis can become sepsis, a life-threatening blood infection.
Another complication is when the rash caused by Stevens-Johnson syndrome affects the eyes, the Mayo Clinic reports. It usually causes irritation and dry eyes. In serious cases, it can cause scarring and tissue damage that leads to blindness. A rare complication involves internal organs. The heart, lungs, liver and kidneys may become inflamed.
Stevens-Johnson syndrome is a serious condition that usually requires hospitalization, the Mayo Clinic says. It is usually triggered by medication, and often the first course of treatment is to take the patient off all non-essential medications until the one causing the problem is detected. Patients are usually treated with nutrition and fluids that are lost through the skin damage. They also receive wound care to soothe the damaged skin and antibiotics to prohibit infection. Recovery can take a few days to several months.
