A 24- year-old sexually active female presents to the clinic complaining of severe itching in the pubic hair region. Upon physical examination, numerous small, white, mobile parasites are identified in the pubic hair, consistent with pubic lice (Phthirus pubis). The patient also reports the presence of bluish-gray macules on the skin, known as maculae ceruleae, which are characteristic of pediculosis pubis. The patient is diagnosed with pediculosis pubis, commonly known as pubic lice or “crabs.” What is the most appropriate first-line treatment for pediculosis pubis?
