Lidocaine is a common drug used in nearly every basic medical procedure due to the numbing effect that it produces. This medication most often comes in the form of a topical spray or cream, an injectable solution, a patch, gel, or a band-aid like sticker attached to the skin at the application site.
As a topical cream, it is applied on the skin to help ease the itching, burning, skin inflammation pain, and produce numbness. The lidocaine injection is used to numb an area before surgery or prior to another medical procedure. It is used by doctors to treat heart arrhythmias and seizures, with proper dosage and administration, of course. This medication is mostly administered by doctors, dentists, nurses, and surgeons in a hospital setting, but it can also be done at home, given the person administering possesses the knowledge of proper administration and disposal of the drug, needles, and other items used in giving this medication.
However, just like any other medicine, there are also lidocaine side effects, but in many cases it causes no, or minor, side effects. Below are the common side effects that you must be aware of. Thus, should any of these occur, call for emergency medical assistance right away.
