Indications:  Erbitux is a liquefied medication used to treat colorectal, and on occasion, kidney cancer. It is administered by a shot that needs to be injected, via a medical syringe, directly into the blood stream. The medication works by binding itself to a particular protein (the epidermal growth factor receptor, or the EGFR) on cancer cells, thus slowing the growth of the cells. It’s imperative that the shot be injected directly into a vein; if done improperly, the shot can do major damage. For example, if the shot is injected into the wrong area of the body, and the medicine is injected beneath a muscle, it can cause serious muscle damage.
