What is the standard intranasal naloxone dosage?

• A. 2 mg/2 mL total (1 mg per nostril)
• B. 0.5 mg per nostril
• C. 4 mg total (2 mg per nostril)
• D. 1 mg total (0.5 mg per nostril)

Answer: (A)

The main idea here is to rapidly reverse opioid effects with a dose that is quickly absorbed through the nasal mucosa. Intranasal naloxone delivers a fast onset by exploiting the efficient absorption across the nasal lining, so starting with a modest, evenly split dose allows quick reversal while keeping administration simple in the field. A total of 2 mg given as 1 mg in each nostril is a common starting approach because it provides enough receptor blockade to often restore respirations promptly, and it’s easy to administer with standard intranasal preparations. If there isn’t an adequate response, doses can be repeated or increased as protocols allow. Smaller doses (0.5 mg or 1 mg total) may be less reliably effective in reversing overdose, while a larger initial dose (4 mg total, such as 2 mg per nostril) might be used in cases of poor response or suspected potent synthetic opioids, but it is not the typical starting dose.
