Multiple-dose vials contain methylparaben [see Warnings and Precautions (5.3)].

Mepivacaine hydrochloride is 2-piperidinecarboxamide, N-(2,6-dimethylphenyl)-1-methyl, monohydrochloride. It is a white crystalline odorless powder, soluble in water, but very resistant to both acid and alkaline hydrolysis. It has the following structural formula:

structural formula carbocaine

                C15H22N2O • HCl

CARBOCAINE (mepivacaine hydrochloride) is a clear and colorless sterile isotonic solution. Each mL of single-dose vial contains 10 mg, 15 mg or 20 mg of mepivacaine hydrochloride (equivalent to 8.71 mg, 13.07 mg, or 17.42 mg of mepivacaine, respectively) with the detailed composition shown in the table. Each mL of multiple-dose vial contains 10 mg or 20 mg of mepivacaine hydrochloride (equivalent to 8.71 mg or 17.42 mg of mepivacaine, respectively) with the detailed composition shown in the table.
