What is the appropriate approach to suspected overdose with unknown substances?

• A. Induce vomiting immediately
• B. ABCs, continuous monitoring, supportive care, consult medical control or poison control, and decontamination if indicated by protocol
• C. Administer universal antidote
• D. Focus only on oxygenation

Answer: (D)

Stabilization and a broad, protocol-driven plan are the key. When the substances are unknown, the first focus is airway, breathing, and circulation, with continuous monitoring of vitals, mental status, and perfusion. Treat symptoms and support the patient’s airway and ventilation as needed, while calling medical control or poison control for substance-specific guidance. Because many unknown overdoses do not have a single antidote, management is mainly supportive and guided by the established protocol. Decontamination may be considered if the protocol indicates it (for example, certain toxins within a specific time window and with a protected airway), but it must be appropriate to the situation and patient condition. Inducing vomiting is generally not recommended due to aspiration risk, and focusing only on oxygenation misses other critical aspects of stabilization. There is no universal antidote that applies to all overdoses, so a comprehensive supportive approach is essential.
