What is the maximum recommended dose of epinephrine for a healthy (ASA I) patient?

• A. 0.2 mg
• B. 0.04 mg
• C. 0.5 mg
• D. 1.0 mg

Answer: (A)

When using epinephrine-containing local anesthetics, the goal is to get the benefits of vasoconstriction and longer anesthesia without causing systemic cardiovascular effects. For a healthy patient (ASA I), the maximum recommended amount per appointment is 0.2 mg of epinephrine. This amount provides a safe balance: enough vasoconstriction to reduce bleeding and prolong the anesthetic, but not so much that it risks significant tachycardia or hypertension in a person without systemic disease. In practice, epinephrine is often supplied in concentrations like 1:100,000, with about 0.02 mg of epinephrine per 1.8 mL cartridge. So the 0.2 mg limit translates to roughly ten of those cartridges, though clinicians tailor use to the procedure and patient response. For patients with cardiovascular disease or other systemic concerns, the limit is much lower (about 0.04 mg).
