Correct answer: A — Stop carbimazole and seek urgent blood test or medical assessment today
Carbimazole can cause agranulocytosis, which may present with fever, sore throat or mouth ulcers. The patient should stop the medicine and seek urgent full blood count and medical assessment. Continuing treatment while symptomatic could be dangerous. Antibiotic treatment should not be started in pharmacy without assessment of neutropenia risk.
