The medical pen injector of the subject invention further includes an adaptor engageable with the body. The adaptor encompasses the distal end of the drug cartridge with the drug cartridge being in the use position. The adaptor includes features for mounting a needle assembly thereto. Advantageously, with the subject invention, a drug cartridge having a large distal end may be accommodated with a drug delivery device, e.g., a pen injector type device.
