Fatal cold medication poisoning in an adolescent
1UC San Diego Medical Center, Dept. of Emergency Medicine, 200 W. Arbor Drive, San Diego, CA 92103-8676, USA.
Background:
Toxicity from the intentional misuse of over-the-counter (OTC) combination cold products has been widely recognized. Adolescents are most frequently involved and dextromethorphan containing products are the most popular. Desired symptoms include stimulatory effects, euphoria, hallucinations, and dissociation. Potential adverse effects include tachycardia, agitation, hyperthermia, acidosis, and coma. However, mortality is rare [ 1-3]. Co-formulated ingredients such as acetaminophen, pseudoephedrine, and antihistamines may also be present and potentiate dangerous effects. We report a case of an adolescent decedent with markedly elevated postmortem chlorpheniramine (CPA) and dextromethorphan (DXM) blood concentrations and no other identifiable cause of death.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
