Correct answer: AContact the prescriber to consider smaller quantities or an alternative

Tricyclic antidepressants are dangerous in overdose due to cardiotoxicity and CNS toxicity. A large quantity may be inappropriate in a patient with overdose history, so risk mitigation should be discussed. The other options either delay appropriate care, use an unsuitable medicine, or miss the main safety issue.
