I am allergic to novacain, septocaine, and lidocaine. what options can the dentist use?

Carbocaine: This is an another anesthetic that can be used for dental anesthesia. Than being said there are very very few actual cases of someone being allergic to local anesthetic. What usually happens is the patient is affected by the Epinephrine that is combined with the local anesthetic. A jittery feeling or a racing heartbeat may result. The dentist can use an anesthetic without epinephrine.

Nucalm: Nucalm is a possibility. Nitrous oxide may be helpful. Also oral anti anxiety could help. See your dentist and discuss these options.

Allergy Test: It is highly suspect that you have a true allergy to lidocaine. It is more likely you are allergic to an additive or preservative in the anesthetic solution. See an allergist to be tested so that you don't have continued dental issues.

Plain carbocaine: The likelihood is that you will tolerate plain carbocaine. It has no vasoconstrictor and no preservatives, the usual cause of allergy to local anesthetics. No worries about latex allergies either, since the stopper is not made of latex.

Testing: Your allergist can also perform novocaine, lidocaine, etc testing to truly determine if you are allergic.

If they are: True allergies and not allergies to preservatives mixed with the local or accidental intravascular injections, then i would recommend avoiding local and trying nitrous oxide or monitored anesthesia care wih sedation or general anesthesia. Discuss your options with your dentist.

Carbocaine: You may have problems with the Epinephrine in the locals you mentioned so have your dentist try Carbocaine which does not contain lidocaine.

Citanest Plain: Very well tolerated by most epinephrine-sensitive patients.. Hard to get. Most docs don't have it. Perpetually on back order.
