Lidocaine Vs Novocaine
Local Anesthetics: Both Lidocaine (xylocaine) and novocaine(procaine) are local anesthetics that anesthetize, or numb. Lidocaine is an amide and novocaine an ester local anesthetic respectively -- this refers to their chemical structure and bonding that dictate onset of action, duration of action and metabolism to some degree. Essentially, they both have the same action. ...Read more
Generally, yes: Practically any drug can cause allergic reaction. Having said that, the true allergy, defined as a reaction mediated by antibodies etc., is more common to novocaine, than to lidociane, particularly if it is in preservative- free solution. Your doctor will help you to determine the right answer after gathering a bit more information. Hope that helps. ...Read more
Yes/no: While Novocaine allergies do occur occasionally, true allergies to lidocaine are extremely rare. If this has actually been documented by an allergist, there are few good alternatives. Many people think they are allergic due to rapid heart rate- this is actually a normal reaction to epinephrine commonly used together. ...Read moreSee 2 more doctor answers

See an allergist: People with allergies to local anesthetics tend to cross-react to medicines within the same chemical group. You've listed medicine from both major anesthetic groups, which is not common. An allergist can perform testing to determine: 1) if you are truly 'allergic' or have other types of reactions, 2) exactly what drugs from each class you react to, 3) if there are drugs you can safely take. ...Read moreSee 2 more doctor answers
Na channel blocker: Yes, it is a sodium channel blocker, so it is used as local anesthetic and as anti arrythmic agent. Local anesthetics (lidocaine ) block the influx of sodium and prevent the generation of an action potential and its transmission along a nerve. ...Read moreSee 1 more doctor answer
Local anesthetics: In combination Lidocaine + prilocaine = EMLA (lidocaine and prilocaine) topical cream. Lidocaine is a local anaesthetic of the amide group and commonly used for this purpose (e.g. dental office). Prilocaine is a local anesthetic of the amino amide type and used for local anesthesia. ...Read moreSee 1 more doctor answer
How much?: If just a tiny bit was consumed say a pea size amount nothing will happen but you may get a numb tongue or posterior pharynx ( back of throat ) for an hour or so. If the entire tube was taken i would see how many milligrams of lido/prilo were in the tube . Much of the medication would be broken-down in the stomach but you would absorb some. If you ate the entire tube i would go to the er. ...Read more
Two different meds: If I understood your question correctly, lidocaine (an amide) is also a local anesthetic, yet chemically it is different from tetracaine (an ester). The chance of allergic reaction is higher with ester-type drug (Novocaine, tetracaine). Duration and metabolism is also different. One should consult a doctor with the specific questions regarding safety. Hope that helps. ...Read more
