Final answer:
To document the intervention, include the date, proposed cost-effective alternative, basis for suggestion, patient's response, and actions taken, ensuring clarity and completeness of records.
Step-by-step explanation:
When documenting the intervention of proposing a more cost-effective alternative to a brand medication for Joe, who has previously filled a generic alternative, it is important to first acknowledge that prescription drugs often have multiple alternatives in the market.
Documentation should be clear and include the date of the intervention, the alternative that was proposed, and a note whether this was based on the pharmacist's professional judgment or a form of Therapeutic Equivalence as recommended by sources such as the U.S. Food and Drug Administration.
Furthermore, the pharmacist should record Joe's response to the suggestion and any actions taken, whether he accepted the new alternative or decided to continue with his current prescription.
