When compounded lidocaine is used for surgery, it is usually cleaned off in 0.5 to 12 hours, as appropriate, and when used for sexual intercourse, it is usually cleaned off after about 5 minutes of application.
Compound Lidocaine has a local anesthetic effect and is indicated for needle puncture (e.g., placing a catheter or taking a blood sample), and local anesthesia of the dermis for superficial surgical procedures. The drug should be administered well in advance of the procedure, usually ranging from half an hour to 12 hours, with some requiring longer or shorter periods, all pending clearance of the drug at the end of the procedure.
Note that contraindications to the use of the drug include hypersensitivity to amide local anesthetics, patients with congenital or idiopathic methemoglobinemia. Note that it can not be used on open wounds and mucous membranes of the genital organs in children.
Local adverse reactions such as pallor, erythema (redness) and edema may occur after administration of the drug, which are transient and mild. The specific use of the drug should be carried out under the guidance of a specialist, and should not be used without authorization.
