Carbocaine anesthetic is used as a dental anesthetic to prevent the transmission of nerve impulses during dental procedures. Carbocaine does not contain Epinephrine. The vasoconstrictor Neo-Cobefrin is present in Carbocaine. Because Neo-Cobefrin does not raise blood pressure as much as Epinephrine, Carbocaine is frequently used on patients with hypertension. It is sold in a 3% or 2% formulation. Carbocaine 2% with Neo-Cobefrin 1:20,000 injections are indicated for longer procedures. Numbness can last up to 5.5 hours with this product. Carbocaine has a rapid onset of 30 seconds to 2 minutes in the maxillary arch and 1 to 4 minutes in the mandibular arch. The generic name for Carbocaine is Mepivacaine Hydrochloride. Mepivacaine is available without a vasoconstrictor.
