|Beyond the Dentist Chair: Novocaine Affects|Allergies|References|
Allergic reactions to Novocaine happen by a case to case basis, and depend on where the drug is injected. Due to the sensitivity of the location, Novocaine injected in the spinal region can respond more adversely then oral injections for dental procedures.
The FDA cautions patients with other allergies or sensitivities to drugs to be careful when being prescribed Novocaine injections. Patients with heart problems or conditions need to use the most caution when receiving Novocaine. Also, any patient already taking a sulfonamide drug should notify the physician because the aminobenzoic acid in the Novocaine molecule stops the action of the sulfonamide.
Possible Side Effects: Spinal Injection
- systemic toxicity– symptoms include: dizziness, tremors, blurred vision, convulsions and nervousness
- hypotension
- post-spinal headache
- spinal nerve paralysis
- palsies
- respiratory problems
- nausea and vomiting
There is no specific treatment for systemic toxicity.
The modernization of anesthesia, specifically lidocaine, has become more hypoallergenic and eliminates some of the possible reactions presented by Novocaine.
