A drug delivery device () for administering a low dose of a medicament includes a housing () and a drug reservoir () disposed in the housing (). A needle () is connected to the drug reservoir (). A pressure applying member () is movably connected to the housing () and is movable between first and second positions. The pressure applying member () does not apply pressure to the drug reservoir () in the first position and applies pressure to the drug reservoir () in the second position to dispense medicament stored in the drug reservoir (). A method of administering a low dose of insulin to simulate a first-phase insulin response of a pancreas is also disclosed.

Low dose prefilled drug delivery device and method

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