TOPEX® Metered Spray is a 20-percent Benzocaine spray that delivers a precise amount of Benzocaine with no over spray. TOPEX Metered Spray is easy to use: Insert the disposable applicator straw into the white nozzle and spray area to anesthetize. The disposable straw reduces concerns of cross contamination and is long enough to reach difficult areas. The unique metered nozzle dispenses a single 6-mg application of 20-percent Benzocaine, without a continuous spray, reducing the risk of methemoglobanemia. TOPEX is available in Wild Cherry Flavor and each 2-oz can delivers approximately 1,000 sprays.
