Abstract: A pen needle (101) for use with a drug delivery device (100) includes a hub body (113) having internal threads (216) to receive the drug delivery device (100). A post (121) is connected to the hub body (113). A needle (103) is rigidly fixed to the post (121). The post (121) is separable from the hub body (113) such that the needle (103) is removed with the post (121). The fluid path is not disturbed by such removal because the entire needle (103) is removed with the post (121). Removal of only the post (121) and needle (103) reduces the volume of waste required for disposal, thereby increasing the effective capacity of a sharps container.
