Answers: Only if you have 0.05% lidocaine. The conversion for lidocaine ( or any medicine ) is simple. Multiply the percent solution by 10...that number of milligrams contained by a cc. If you have 2% lidocaine there would be 20 mg. surrounded by each cc.or 400 mg in 20 cc.
perchance or maybe not, it depends on the strength of the liquid.. mg is a test of weight, and cc is a measure of volume... it depends on the concentration of the fluid. call and ask the pharmacist for help fairly than guessing.
