The present invention relates to novel drug delivery technology in the form of solid dose injection devices and methods which utilise a blade that is pushed into the skin to a predetermined depth before the before a solid drug formulation is pushed into the cut made by the blade. Thus the present invention also relates to delivering a therapeutic compound to a human or animal in the form of a solid dose injection comprising: providing an injection device comprising a casing an actuation mechanism capable of ei generating a force, a blade, a solid drug formulation and a means for pushing said solid drug formulation wherein the blade is inser ted to a predetermined depth in the skin and, following insertion of the blade, the device is actuated such that the actuation mechanism capable of generating a force acts on the means for pushing to push the solid drug formulation out of the casing and into the human or animal body.
