Correct answer: D — Apply terbinafine regularly, keep toe spaces dry and avoid shared towels
Apply terbinafine regularly, keep toe spaces dry and avoid shared towels: Localised interdigital tinea pedis is suitable for topical terbinafine, with adherence and hygiene measures reducing persistence and transmission. Apply terbinafine on symptomatic days and stop when pruritus first resolves: Intermittent symptom-led use risks incomplete eradication and recurrence. Apply terbinafine under an airtight dressing and change it each morning: Occlusion increases moisture, which favours fungal persistence and maceration. Apply terbinafine to skin and nails as a single definitive course: Topical skin cream does not reliably treat onychomycosis and nail disease requires separate assessment. Apply a potent corticosteroid first and terbinafine after inflammation settles: Corticosteroid monotherapy can mask or worsen fungal infection and is not routine treatment.
