First-Line Treatment for Polymorphic Light Eruption
Polymorphic light eruption (PLE) presents with an itchy rash that settles with sun avoidance. First-line management combines preventive and suppressive measures to control symptoms and prevent recurrence.
Clinical Scenario
This is a first-line protocol for PLE — targeting patients in whom preventive strategies and suppressive measures are initiated together to settle the rash and relieve itch.
Approach (partial overview)
Management involves avoiding intense UV exposure during peak hours, protective clothing, and a broad-spectrum sunscreen, alongside a topical agent directed at itch and mild episodes. The full structured regimen details the complete sequence and clinical guidance.
Treatment Goal
For most patients with PLE, a mild rash settles within a few days of sun avoidance, with relief of itch.
