The exact cause of Stevens-Johnson syndrome can't always be identified. Usually, the condition is an allergic reaction in response to medication, infection or illness.
Medications are most often the cause of Stevens-Johnson syndrome. Drugs commonly associated with Stevens-Johnson syndrome include:
- Anti-gout medications, such as allopurinol
- Nonsteroidal anti-inflammatory drugs (NSAIDs), often used to treat pain
- Penicillins, which are used to treat infections
- Anticonvulsants, which are used to treat seizures
Infections that can cause Stevens-Johnson syndrome include:
- Herpes (herpes simplex or herpes zoster)
In some cases, Stevens-Johnson syndrome may be caused by physical stimuli, such as radiation therapy or ultraviolet light.
