Xylocaine Topical Solution Dosage

When 4% Xylocaine Topical Solution is used concomitantly with other products containing lidocaine HCl, the total dose contributed by all formulations must be kept in mind.

The dosage varies and depends upon the area to be anesthetized, vascularity of the tissues, individual tolerance, and the technique of anesthesia. The lowest dosage needed to provide effective anesthesia should be administered. Dosages should be reduced for children and for elderly and debilitated patients. The maximum dose should not exceed 4.5 mg/kg (2 mg/lb) of body weight. Although the incidence of adverse effects with 4% Xylocaine Topical Solution is quite low, caution should be exercised, particularly when employing large volumes, since the incidence of adverse effects is directly proportional to the total dose of local anesthetic agent administered.

The dosages recommended below are for normal, healthy adults:

When used as a spray, or when applied by means of cotton applicators or packs, as when instilled into a cavity, the suggested dosage of 4% Xylocaine Topical Solution is 1 to 5 mL (40 to 200 mg lidocaine HCl), ie, 0.6 to 3 mg/kg or 0.3 to 1.5 mg/lb body weight.

NOTE: The solution may be applied with a sterile swab which is discarded after a single use. When spraying, transfer the solution from the original container to an atomizer.
