Lignocaine, also called lidocaine in many countries, is a fast‑acting local anesthetic. It blocks the nerves that send pain signals, so you feel numb instead of sore. Doctors use it for everything from a tiny dental drill to a big skin biopsy. You’ll find it in creams, gels, injection vials, and even patch form for chronic pain. Because it works quickly and wears off in a few hours, it’s a go‑to choice for short‑term pain control.
In everyday life, lignocaine shows up in a few places you might not expect. A dentist will spray it on your gums before a filling, and a dermatologist might inject it before removing a mole. Over‑the‑counter creams that soothe insect bites or minor burns often contain a small amount of lignocaine. For more serious pain, doctors can give an injection into a joint or around a nerve, giving relief that lasts several hours. Sports medicine clinics also use lignocaine patches to ease muscle soreness after an injury.
When you use lignocaine the right way, it’s usually safe. The biggest risk is using too much, which can cause a tingling feeling, dizziness, or even a fast heartbeat. That’s why doctors calculate the dose based on your weight and the area being treated. If you have a history of heart problems, tell your doctor—lignocaine can affect heart rhythm in high doses. Allergic reactions are rare, but watch for rash, swelling, or trouble breathing after a first use.
If you’re buying a lignocaine product online, double‑check that the pharmacy is licensed and that the product lists the exact concentration. In Australia, the TGA requires clear labeling for any local anesthetic sold without a prescription. Always read the package insert for storage tips; most forms must stay cool and dry to keep their potency.
Mixing lignocaine with other numbing agents or with alcohol‑based products can increase the chance of skin irritation. Keep it away from open wounds unless a health professional tells you otherwise. And never apply more than the recommended amount—more isn’t faster, it’s just riskier.
