A patient is actively seizing with a history of seizures. Which medication and dosing approach is listed?

• A. Diazepam 5 mg IM/IV/IO
• B. Midazolam 0.1 mg/kg IM/IN/IV/IO; max dose of 5 mg
• C. Lorazepam 2 mg IV
• D. Phenytoin 100 mg IV

Answer: (B)

Rapid control of an actively seizing patient relies on a benzodiazepine that can be delivered quickly through multiple routes. Midazolam is ideal here because it acts fast and can be given by IM, intranasal, IV, or IO routes, so you can treat the seizure promptly even if IV access isn’t readily available. The weight-based dose of 0.1 mg/kg up to a maximum of 5 mg per dose lets you tailor the amount to the patient’s size, reducing the risk of underdosing in larger individuals and oversedation in smaller ones. This approach also allows repeat dosing if seizures persist, which aligns with common EMS practice. Other options are less flexible or slower to act in the field: diazepam often requires IV access and has slower redistribution; lorazepam IV is effective but again depends on IV access and isn’t as versatile for non-IV routes; phenytoin is not used for immediate seizure cessation and has slower onset.
