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. This article will dive deeper into everything you need to know about lidocaine.
How Does Lidocaine Work?
Lidocaine works by temporarily blocking the transmission of nerve impulses. This enables the numbing effect on the area where it is applied. 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.
Are There Any Side Effects Associated with Lidocaine?
The most common side effects of lidocaine are dizziness, drowsiness, and headache. More severe side effects may include seizures, vision changes, and difficulty breathing. If you experience these side effects after using lidocaine, seek medical attention immediately.
