Lidocaine Hydrochloride gel usually provides anesthesia in about 5 minutes, and the effect time will last for about half an hour or an hour. Lidocaine gel hydrochloride is a local anesthetic that can be used for some minor surgical procedures, such as some skin surgery or superficial surgery, or oral surgery for tooth extraction, etc. Lidocaine gel can be applied for local anesthesia. The drug will make the local surgical site painless while the surgery is in progress and reduce the patient’s pain during the surgery, but the drug may cause allergic reactions in some people when it is applied and should be taken seriously.
