Everything You Need to Know About Lidocaine

Lidocaine is a medication that numbs a specific tissue area. Also known as a local anesthetic, lidocaine can be mixed with small amounts of epinephrine to allow for larger doses of numbing. Additionally, lidocaine can help decrease bleeding and prolong the numbing effect. Lidocaine is often used to relieve pain and vascular spasms associated with injections.

How Does Lidocaine Work?

When mixed with epinephrine, lidocaine can also help to constrict blood vessels, which helps to reduce bleeding. Additionally, epinephrine can help prolong the numbing effect of lidocaine. 

Lidocaine is available in various forms, including creams, gels, sprays, and injections. When applied topically, lidocaine typically begins working within minutes. The effects of injected lidocaine usually last for 30 to 60 minutes.
