A pen-type delivery device and a method for administering parathyroid hormone are provided, allowing for testing and injection of a single, predetermined dose. This method is a three-step method using visual cues to set the trial dose and the injected dose. The device is made up of a minimum number of parts including a housing, a dispensing head, a substantially cylindrical release device located at the proximal end of the dispensing head, and a male threaded drive rod. In addition, the pen-type device contains a mechanism that prevents the user from setting a dose beyond what is left in the cartridge. |
