Lidocaine cream works by temporarily blocking the pathway of pain signals along nerves. Lidocaine cream 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.
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.
Possible side effects are likely to include swelling or redness at the application site, unusual sensations on skin or pale skin. Severe to rare side effects may include allergic reactions like hives, rash, itchiness, facial swelling, and difficulty breathing or tightness in the chest.
Medicines affect different people in different ways. If you experience any unusual effects while using, stop and contact you medical provider immediately. Treatment should be symptomatic and supportive.
