Chemotherapy labels ensure that medicines that will help certain patients (chemotherapy) are handled properly so they do not harm others in the process. Chemotherapy labels are a type of pharmacy label that provide a cautionary warning that a toxic substance is being handled. Initially, chemotherapy labels communicate the fact that the dispenser of said medication must take special precautions when handling it, but further, it highlights the fact that this medication must be disposed of in a biohazards container. This is not something that just anyone should come into contact with.
