Prilido Cream works by temporarily numbing the skin and surrounding area. It should be used in the dose and duration as advised by your doctor. This medicine is for external use only. Make sure that the affected area is clean and dry before applying this medicine. Apply a thin layer and rub it gently to form a layer of about 2-3mm. After that, apply an occlusive dressing to protect the area. Keep the dressing for a minimum of 2 hours before any scheduled treatment or surgery. Avoid getting it into your eyes or mouth. If accidental exposure occurs, rinse thoroughly with water.
