Gebauer's Ethyl Chloride instant topical anesthetic spray (vapor coolant) is FDA cleared to temporarily control the pain associated with injections, starting IVs and venipuncture, minor surgical procedures, and minor sports injuries. 

When topically applied to the skin, Ethyl Chloride creates an instantaneous numbing and cooling effect on the surface of the application site by the immediate evaporation of the product from the skin surface. The cooling sensation produced is directly related to the type of stream and the distance from the point of contact.
