What is the epinephrine dose for adult anaphylaxis?

• A. 1:1000 0.01 mg/kg (MAX 0.5 mg)
• B. 1:1000 0.1 mg/kg
• C. 1:1000 0.001 mg/kg
• D. 1:10000 0.3 mg

Answer: (A)

Treating adult anaphylaxis with epinephrine uses the 1:1000 concentration given intramuscularly, with dosing that can be adjusted for body weight but kept within a safe upper limit. The option that uses 0.01 mg/kg (which is 10 micrograms per kilogram) and caps at 0.5 mg per dose fits this approach: it scales with how big the person is but prevents giving too much in larger adults by enforcing the max. In practice, this means smaller adults receive more precise weight-based dosing, while larger adults won’t exceed 0.5 mg in a single administration. Other choices either apply an inappropriate per-kilogram amount or use the wrong concentration/route (for example, 1:10000 is typically used for IV administration in advanced resuscitation, not the standard IM dose for anaphylaxis).
