Correct answer: B — Take doses on an empty stomach where possible

Flucloxacillin absorption is reduced by food, so it is usually taken on an empty stomach. Practical timing advice is needed to help adherence around shift work. The patient should complete the course and seek review if cellulitis worsens or systemic symptoms develop.
