How often should a patient's medication history be reviewed?

A patient's medication history should be reviewed regularly or whenever there is a change in their medication regimen because this practice is crucial for ensuring ongoing safety and effectiveness of the patient's treatment. Medications can interact with each other, and changes in a patient's health status or the introduction of new treatments can necessitate reevaluation of their current medications.

Regular reviews help healthcare providers catch potential adverse effects, manage polypharmacy more effectively, and ensure that the patient adheres to the prescribed regimen. It’s essential not only during initial visits or specific intervals but should be an ongoing process, particularly as patients experience changes in their health or medication needs.

In contrast, limiting the review to only the initial visit does not account for the dynamic nature of a patient’s health and medication. Similarly, requiring a review only once a year or every six months may miss crucial changes or complications that arise outside of those set times. Regular attention to a patient's medication history is key to providing safe and effective care.
