Process for the computer generation of prescribing information, and printable calendar, for a medicinal drug taper (escalating or deescalating). This process allows the user, generally a practicing physician, to use an application on a variety of different platforms. This is useful in any medication in which the dosage must be escalated or de-escalated. This is perhaps most common with respect to steroid prescriptions, wherein the physician prescribes dosages that steadily decrease over time, especially if the patient has been on the steroids for an extended period of time. The application also gives physicians the option to increment dosage over time, and ultimate control over when the daily doses are determined. The calculation and dosing calendar will be available to the physician, patient, any attending nurse, and any prescribing pharmacist.
