Men generally use lidocaine spray to reduce the sensitivity of the glans, usually half an hour before sex. Lidocaine spray is an amide-based local anesthetic that is generally used to reduce the sensitivity of the glans by spraying a small amount of lidocaine spray in the coronal area of the penis half an hour before sex. And 3 to 5 minutes before sex, wash off any residual medication from the lidocaine spray that remains on the surface of the glans. You should also avoid spraying too much to avoid adverse reactions such as tinnitus, euphoria and irritability. The use of lidocaine spray is prohibited for patients with allergies, severe liver and kidney problems, and broken skin. Avoid contact with the eyes when using and wash your hands after use. Long-term use may cause some dependence. It is recommended that men should use Lidocaine Spray under the guidance of a professional doctor to avoid blind use of the drug, which may cause adverse reactions.
