A drug delivery device is disclosed that may include a skin penetrating assembly having a support defining an upper surface and a lower surface. The skin penetrating assembly may also include a plurality of skin penetrating members extending outwardly from the lower surface. Each skin penetrating member may define a channel for receiving a drug formulation. In addition, the device may include a reservoir positioned adjacent to the upper surface of the support for initially retaining the drug formulation. The reservoir may include a top surface and a bottom surface and may define a plurality of passages extending between the top and bottom surfaces. The passages may be configured such that the drug formulation is retained within the passages against gravity.
