A drug delivery device may include a housing having an opening and a drug storage container including a delivery member having an insertion end configured to extend at least partially through the opening during a delivery state. The device may also include a guard moveably positioned adjacent to the opening and a plunger having a generally cylindrical body portion extending along a longitudinal axis of the container and at least one flange extending radially outwardly from the body portion, wherein the plunger is moveable toward the distal end of the container to expel a drug through the delivery member. The device may further include a plunger biasing member configured to urge the plunger toward the distal end of the container and a releaser member defining a guide configured to receive the at least one flange and an indicator configured to generate an audible signal indicating an end of drug delivery.
