Maximum Recommended Dose Calculation for Lidocaine

The formula is as follows: maximum allowable dose (mg/kg) x (weight in kg/10) x (1/lidocaine percentage) = maximum recommended dose. Thus, if maximum allowable dose is 7 mg/kg for lidocaine with epinephrine, using 1% lidocaine with epinephrine for a 60-kg patient: 7 x 6 x 1 = 42 mL lidocaine. Maximum allowable doses for lidocaine without and with epinephrine are 3 mg/kg and 7 mg/kg, respectively. To calculate the maximum recommended dose represented as number of carpules or cartridges, divide the maximum recommended dose in mL by 1.7
