A drug container is positioned within the housing, with a plunger movably positioned within the drug container and with a needle fluidically connected to the drug container and configured to define at least a portion of a fluid flow path between the drug container and the human body surface. The drug delivery device also includes a buzzer and an indicator light for providing indications. A controller is configured to control the components of the drug delivery device to execute a drug delivery routine. A method of delivering pegfilgrastim from a drug delivery device includes providing an audible indication that the drug delivery device is activated, executing a drug delivery routine, and providing first and second indications during drug delivery.
