Summary
Lidocaine is used to relieve pain and discomfort from minor burns, insect bites, and skin irritations. It numbs the area where it's applied, blocking pain signals from reaching the brain. Lidocaine is also used in medical procedures to numb specific areas, making it easier to perform the procedure without causing pain.
Lidocaine works by blocking nerve signals in the body, which prevents pain signals from reaching the brain. This numbing effect provides temporary relief from pain and discomfort. Lidocaine is effective for minor burns, insect bites, and skin irritations. It is also used in medical procedures to numb specific areas.
Lidocaine is usually applied topically, meaning you put it directly on your skin. Follow your doctor's instructions on how much to use and how often. Typically, you apply it to the affected area as needed for pain relief. Lidocaine patches are typically applied once every 24 hours and should not be worn for more than 12 hours in a 24-hour period.
Common adverse effects of lidocaine include skin irritation, redness, or swelling at the application site. These effects are usually mild and temporary. Serious adverse effects are rare but can include allergic reactions, which cause rash, itching, or difficulty breathing. Systemic toxicity, which affects the heart and nervous system, can occur with overuse.
Lidocaine should not be used on large areas of the body or for prolonged periods, as this can lead to serious side effects. Overuse can cause systemic toxicity, which affects the heart and nervous system. Symptoms of toxicity include dizziness, confusion, and irregular heartbeat. Avoid using lidocaine on broken or irritated skin.
