Affecting between 1 and 5 people per million annually, Stevens-Johnson syndrome (SJS) is a rare but life-threatening condition characterized by widespread blistering and skin peeling. Understanding what type of ADR is Steven Johnson syndrome is critical for both clinicians and patients, as it is classified as a severe cutaneous adverse reaction (SCAR) and requires immediate medical intervention.

While many adverse drug reactions (ADRs) manifest immediately, delayed adverse drug reactions (DADRs) can emerge days, weeks, or even years after starting a medication, complicating diagnosis and patient management. These reactions are often mediated by the immune system and require a vigilant clinical approach to identify and manage correctly.
