MSRA-0336
A 35-year-old office worker complains of widespread pruritus for the last 2 weeks. She has no particular history of note, though she is currently staying with her parents due to financial difficulties. She has noticed the itching is particularly bad at night. On examination, she has several circular erythematous lesions on her arms and legs.
Given the likely diagnosis, what is the most appropriate first-line treatment option?
