Lidocaine: Uses, Side Effects, and Drug Interactions

# Lidocaine Overview Lidocaine is a medicine that numbs pain in your skin and the area around it. Doctors and dentists use it to stop pain during small procedures like removing stitches, treating minor cuts, or doing dental work. It works by blocking pain signals in your nerves, so you don't feel as much discomfort. You can find lidocaine in different forms, like creams, sprays, or injections. It works pretty quickly and is commonly used because it's safe and effective when used the right way. There are some important safety rules to follow when using lidocaine. Never use more of the medicine than your doctor tells you to use, because too much can cause serious problems. Keep lidocaine away from children because it's dangerous if they swallow it or use too much. Don't use it on large areas of skin, near your eyes, or on broken or irritated skin unless your doctor says it's okay. If you're pregnant or breastfeeding, talk to your doctor before using lidocaine. If you have any side effects like swelling, difficulty breathing, or feeling dizzy or confused after using it, stop using it and call your doctor right away.
