Local anesthesia requires no home care. But the procedure itself may require monitoring and treatment. The procedure usually causes more problems at home than the medication. The person may feel some discomfort at the procedure site as the numbing medication wears off.
Local anesthesia is unlikely to cause any complications. However, allergic reactions are possible and may cause temporary breathing problems. In rare cases, if the medication is accidentally injected into the bloodstream, or too much is used, seizures or arrhythmias may occur.
The American Society of Anesthesiologists recently issued a warning about the potential side effects and interactions of herbal remedies with medications used before, during, and after surgery. The group recommends discontinuing all herbal remedies and supplements at least two weeks before planned surgery.
