Lidocaine cram works by temporarily blocking the pathway of pain signals along nerves. Lidocaine cram does this by stopping the sodium entering the nerve ending at the site of the pain. This prevents an electrical signal building up and passing along the nerve fibers to the brain.

Pharmacokinetic:

Lidocaine may be absorbed following topical administration to mucus membranes, its rate and extent of absorption depends upon the specific site of application, duration or exposure, concentration and the total dosage. You may experience reddening of the procedure area.
