For pediatric dystonic reaction, which dosing is specified?

• A. Benadryl: 50 mg IV/IO/IM
• B. Benadryl: 0.5 mg/kg IV/IO/IM
• C. Benadryl: 2 mg/kg IV/IO/IM
• D. Benadryl: 1 mg/kg IV/IO/IM (Diluted) (Max 50 mg)

Answer: (D)

Weight-based dosing is essential for children because their size and metabolism vary widely. For a pediatric dystonic reaction, diphenhydramine is given at 1 mg per kilogram of body weight, via IV, IO, or IM. When given intravenously, it should be diluted to reduce irritation and allow a controlled administration. The total dose should not exceed 50 mg to prevent overdose in larger children and adolescents. A fixed 50 mg dose ignores weight and could be too high for small children, while doses like 0.5 mg/kg or 2 mg/kg don’t align with the standard therapeutic range for this use. So, 1 mg/kg (diluted) with a max of 50 mg best follows safety and efficacy guidelines.
