What is lidocaine, and how does it work?
Short answer
Lidocaine is a local anesthetic that temporarily blocks pain signals in the area where it is applied. Mouth products may ease pain from sores, while certain sprays may reduce penile sensitivity. Results vary. Each product has its own directions, and mouth and genital products are not interchangeable.
Lidocaine is a local anesthetic, which means it numbs a specific area rather than putting you to sleep. It blocks signals in nearby nerves for a short time. Depending on the product, it may be used on skin or moist tissue inside the mouth.
A prescribed mouth rinse may help ease pain from mouth sores. A spray intended for penile use may reduce sensitivity during sex. Results vary. Lidocaine does not treat every cause of mouth pain or premature ejaculation, and numbing an area does not mean the underlying problem has healed.
Different lidocaine products can have different strengths, ingredients, and approved uses. Do not use a mouth product on the penis or a genital spray in the mouth unless your prescriber specifically directs you to do so.
A licensed physician in your state, or a licensed dentist for dental care, decides whether treatment is appropriate. Share your symptoms, allergies, health conditions, and medication list before using lidocaine.
