Stevens Johnson Syndrome

Stevens Johnson syndrome, also known as SJS, is a severe disorder of mucous membranes. It can have signs and symptoms similar to those of severe erythema multiforme, a skin condition that causes blistering and erosion of the skin and mucous membranes, especially in the mouth. Doctors believe this disorder is an allergic or hypersensitivity reaction.

Known causes include:

• Certain medications, including sulfonamide, penicillin, antibiotics, Dilantin (phenytoin) and Bextra (valdecoxib)
• Bacterial and viral infection, such as the herpes simplex virus and mycoplasma
• Radiation therapy
