Mepivacaine

Generic: Mepivacaine Hydrochloride

Rx only

Local anesthetic✓ FDA-verified

Mepivacaine is a local anesthetic used to numb specific areas in the mouth during dental procedures for both adults and children. It works by blocking the nerves that send pain signals, helping you feel comfortable during treatment. The medication is typically injected by a dentist, with a starting dose of one cartridge (which contains about 34 to 51 mg), and the maximum dose should not exceed 400 mg for adults, depending on body weight for children. It's important to know that mepivacaine should not be used if you have a known allergy to amide-type local anesthetics. Additionally, caution is advised if you have heart conditions, as the medication can interact with other drugs that affect heart function.
