What is the maximum total dose of naloxone that can be administered?

• A. 2 mg
• B. 10 mg
• C. 0.4 mg
• D. 5 mg

Answer: (B)

Naloxone is given in small, titrating doses until the patient’s breathing improves, rather than a single large dose. The goal is to reverse opioid effects while avoiding abrupt withdrawal and other complications. In typical EMS practice, there is a ceiling on how much naloxone can be given overall—the cumulative maximum is 10 mg. This means you can continue giving 0.4 mg increments (reassessing each time) until the patient shows adequate respiration and consciousness, up to a total of 10 mg. Doses like 0.4 mg are the starting amounts, while 2 mg or 5 mg are not the total maximum by protocol, and 10 mg represents the cap on the total amount you’d administer. If reversal isn’t achieved after reaching the cap, continue monitoring and transport for further care rather than pushing more naloxone.
