Controlled Drugs
The Controlled Drugs report (accessed in More > Inventory & Services > Manage > Controlled Drugs) displays a dispensing log of any products you have set to Controlled Drug? = Yes that were dispensed over a specified date range. You can filter the report by product category tag and location.
When you select a record on the report, the system directs you to the client invoice that includes the controlled drug.
