Early identification and withdrawal of the offending drug are critical for managing severe cutaneous adverse reactions (SCARs), such as Stevens-Johnson syndrome and toxic epidermal necrolysis, to improve patient outcomes and prevent long-term complications.
Area of Science:
- Dermatology
- Pharmacology
- Clinical Medicine
Background:
- Severe cutaneous adverse reactions (SCARs) encompass a range of potentially life-threatening dermatological conditions.
- Examples include Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalised exanthematous pustulosis (AGEP).
Purpose of the Study:
- To highlight the critical importance of early diagnosis and drug withdrawal in managing SCARs.
- To emphasize the role of supportive therapy and the potential for long-term sequelae.
Main Methods:
- This review synthesizes current understanding of SCARs presentation, diagnosis, and management.
- Focus is placed on the etiological role of culprit drugs and the impact of timely intervention.
Main Results:
- Prompt identification and cessation of the causative agent are paramount for improving patient prognosis in SCARs.
- Supportive care forms the cornerstone of treatment for these severe reactions.
- Long-term sequelae can significantly impair survivors' quality of life, even if not immediately apparent.
Conclusions:
- Effective management of SCARs hinges on early recognition and withdrawal of the implicated drug.
- Supportive measures are essential, and awareness of potential long-term complications is crucial for comprehensive patient care.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
