SJS and TEN are life-threatening reactions. If left untreated they can result in many long term complications including dry-eye syndrome, photophobia and permanent blindness. Damage to the lungs may also occur leading to inflammation of the airways and lung. Other complications may include loss of nail beds, scarring of mucous membranes, arthritis and chronic fatigue syndrome. Skin detachment can also be extremely severe, requiring treatment at a burns unit.
