There are some commercial products available that are designed to alleviate pain from venipuncture.
Cream: A topical cream can be applied to numb the venipuncture site. Apply well in advance to be effective. Always refer to manufacturer's instructions before use on patients. Be certain to determine that no allergy exists before using the product on a child.
Mechanical device: A mechanical device can be used to stimulate nerves surrounding the venipuncture site to numb the site. This device must be used according to the manufacturer's instructions.
Vein Viewer: This device enables the phlebotomist to determine the flow of blood thereby identifying the presence and direction of a vein. This device does not aid during palpation of the vein to determine vein health, diameter or depth.
