Iontophoresis is a technique for delivering dermal analgesia quickly (in 10 to 20 minutes) with minimal discomfort and without distorting the tissue. The Numby 900 iontophoretic drug-delivery system is a handheld device with two electrodes that uses a mild electric current to deliver charged ions of lidocaine 2% and epinephrine 1:100,000 solution into the skin. The device is powered by a 9-volt battery.

Local anesthetic agents, such as those administered through iontophoresis, should be considered before IV insertion.1 Because iontophoresis acts quickly, it’s an excellent choice for numbing an IV insertion site, especially in children.
