COVID-19 Impact On Pharmacies & The Capsa Solution

Pharmacies are dealing with pandemic strain: preparing for testing or vaccinations, more 90-day fills or emergency fills, staff absences, home deliveries, and altered workflows to accommodate staff and patient safety. These stress the core function of filling prescriptions quickly and accurately. The KL1 simple counter is a ready-to-go solution that needs no I.T. connection or training, is simple to clean, and handles higher Rx counts to save time and strain. Plus inventory counts, especially C-II, need to be maintained at high-stress periods.
