Correct answer: B — Advise urgent medical assessment and stop further doses until reviewed

Early rash with mucosal symptoms may indicate severe cutaneous adverse reaction. In this scenario, the pharmacist should prioritise safe supply, appropriate counselling and timely referral or clarification where needed. This is the single best answer because the other options would either delay assessment, ignore a clinically significant risk, or create an unsafe legal or professional outcome.
