What is the initial dose of Midazolam for seizure treatment when given IM/IN?

• A. 5 mg IV
• B. 2 mg IM
• C. 10 mg IM/IN
• D. 8 mg IV

Answer: (C)

When treating a seizure with midazolam via non-IV routes, the goal is to achieve rapid control without needing IV access. The absorption from intramuscular and intranasal routes can be variable, so a higher initial fixed dose is used to ensure the medication reaches effective levels quickly.

The standard starting dose by IM or intranasal administration is 10 mg. This amount is chosen to maximize the chance of stopping the seizure on the first try across a range of patients. If seizures persist, the protocol may allow repeating the dose after a short interval, following safety guidelines and maximum total dosing.

This differs from IV dosing, which is typically weight-based (and usually given as smaller, titratable doses) because IV delivers faster and more predictable blood levels. Always monitor for airway compromise and respiratory depression and be prepared to manage it.
