Abstract

One or more embodiments relate, generally, to a reusable accessory for a medication injection pen. Such a reusable accessory may be adapted to be reversibly attached to a medication injection pen, and configured to detect an event associated with an injection of medication from the medication injection pen. It may also be configured to determine a percentage of medication that remains active for injection by the medication injection pen based on timing information and dosing event information.
