Summary

Polypharmacy is a growing silent challenge in elderly care. While multiple medicines may be necessary, excessive or unreviewed prescriptions can lead to serious complications. Careful monitoring, periodic review, and rational prescribing are essential to ensure that medicines improve health rather than compromise it
