This is an innordinate waste of money on several counts:
— Manufacturers have to package all prescription to fit the 28 day limit. This adds significantly to the cost of the medicine.
— Visits to the GP are increased dramatically, thus wasting much of the GP's time and adding much to the cost of the NHS.
— It wastes time for each individual ti have to schedule appointments with the GP.
— Adminstrative tracking for all patients becomes very difficult and costly.
