Pediatric Drug Interactions with Brompheniramine

• Contraindicated with MAOIs due to potentiated anticholinergic and vasopressor effects.
• Additive sedation with opioids, benzodiazepines, and alcohol—counsel families on monitoring.
• Combining with other anticholinergic medications increases risk of urinary retention, blurred vision, and constipation.
