A method and apparatus are disclosed for delivery of a drug to a recipient. In some embodiments, the delivery apparatus may include a mechanical drive train. Motion of the drive train may drive priming of the device. Subsequently motion of the drive train may discharge the drug. The priming may include unsealing a drug reservoir and/or locking a door. In some embodiments, the rate of discharging may be controlled and/or adjustable. Optionally the apparatus may be disposable. Optionally, the apparatus may have a base that is attachable to the recipient. Optionally, motion of the drive train may be parallel to the base of the apparatus. Optionally, the apparatus may release a hypodermic needle into the recipient. Optionally, release of the hypodermic needle may be in a direction non-parallel and/or orthogonal to the motion of the drive train.
