[Two Cases at Community Pharmacies of Mercaptopurine Removal from a Disk-type Powder-packaging Machine by Wiping It with Water].

"Leukerin powder 10%" containing mercaptopurine (6-MP) is an oral anticancer drug that requires careful handling. As a powder formulation, there are risks of exposure due to scattering during dispensing and possible 6-MP contamination to other drugs due to adhesion to the packaging machine. We previously reported that wiping with an alcohol-containing towel is useful for removing scattered powder after dispensing.
