[KEY POINTS FOR DRUG ERUPTIONS IN DAILY PRACTICE].

Area of Science:

• Dermatology
• Pharmacology
• Clinical Medicine

Background:

• Drug eruptions are frequent mucocutaneous adverse reactions affecting 0.1-1% of patients.
• Diagnosis is challenging due to diverse presentations and differential diagnoses like viral exanthems.
• Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening conditions requiring prompt recognition.

Purpose of the Study:

• To outline a diagnostic strategy for drug eruptions.
• To emphasize the importance of identifying causative agents.
• To reduce mislabeling of drug allergies and improve pharmacotherapy.

Main Methods:

• Comprehensive evaluation of medication history, infection status, latency, and clinical phenotype.
• Consideration of diagnostic tests like drug-induced lymphocyte stimulation test, skin testing, and drug provocation.
• Selection of diagnostic modalities based on clinical phenotype, severity, and timing.

Main Results:

• A structured, time-conscious diagnostic approach is essential.
• Accurate identification of culprit drugs prevents recurrence and preserves future therapeutic options.
• Appropriate diagnostic strategies can reduce incorrect drug allergy labeling.

Conclusions:

• Early recognition and accurate diagnosis of drug eruptions are critical.
• Identifying the causative drug is paramount for patient safety and future treatment.
• A systematic diagnostic strategy enhances pharmacotherapy safety and efficacy.
