Correct answer: D — Review theophylline after smoking cessation

Tobacco smoke induces theophylline metabolism; stopping can increase levels and toxicity risk. 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.
