What is the maximum safe dose of lidocaine with epinephrine?

The maximum safe dose of lidocaine with epinephrine is 7 mg/kg. This dosage limit is implemented to minimize the risk of systemic toxicity, which can occur if too much lidocaine is administered. Lidocaine, as a local anesthetic, can cause significant cardiovascular and central nervous system effects if dosed excessively. Epinephrine is added to lidocaine to prolong its effect and to reduce bleeding in the surgical area, but it does not increase the maximum allowable dose of lidocaine itself. Therefore, adhering to the 7 mg/kg guideline is crucial for patient safety while still benefiting from the vasoconstrictive properties of epinephrine in combination with the local anesthetic. This makes 7 mg/kg the clinically accepted maximum dosage for this combination in most situations.
