DOSAGE AND ADMINISTRATION
Continuous Intravenous Infusion: Following bolus administration, intravenous infusions of lidocaine hydrochloride may be initiated at the rate of 1 to 4 mg/min of lidocaine hydrochloride (0.014 to 0.057 mg/kg/min; 0.006 to 0.026 mg/lb/min). The rate of intravenous infusions should be reassessed as soon as the patient’s basic cardiac rhythm appears to be stable or at the earliest signs of toxicity. It should rarely be necessary to continue intravenous infusions of lidocaine for prolonged periods.
Solutions for intravenous infusion may be prepared by the addition of one gram (or two grams) of lidocaine hydrochloride to one liter of 5% dextrose in water using aseptic technique. Approximately a 0.1% (or 0.2%) solution will result from this procedure; that is, each milliliter will contain approximately 1 mg (or 2 mg) of lidocaine hydrochloride. In those cases in which fluid restriction is medically appropriate, a more concentrated solution may be prepared.
Lidocaine Hydrochloride Injection, USP has been found to be chemically stable for 24 hours after dilution in 5% dextrose in water. However, as with all intravenous admixtures, dilution of the solution should be made just prior to its administration.
When administering lidocaine hydrochloride (or any potent medication) by continuous intravenous infusion, it is advisable to use a precision volume control I.V. set.
-------------Pediatric: Controlled clinical studies in the pediatric population to establish dosing schedules have not been conducted. The American Heart Association’s Standards and Guidelines recommends a bolus dose of 1 mg/kg, and an infusion rate of between 20-50 µg/kg/min for prolonged therapy. When drug clearance is reduced, as in patients with shock, congestive heart failure or cardiac arrest, the infusion rate should not exceed 20 µg/kg/min.
NOTE: Regarding Prolonged Infusions: There are data that indicate the half-life may be 3 hours or longer following infusions of greater than 24 hours in duration. Do not use if solution is discolored or cloudy.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.
