i will be teaching you how to fill a prescription. first step you do is you get the refill paper from the printer and put it in the basket with the prescription.then by looking at the prescription you now know which medication medication you have to get from the shelf. to make sure you get the correct medication, you must scan the refill paper and the medication so that if it is incorrect it will show up on the COMPUTER screen.next step is to attach the refill paper tag which includes the price and patients name to prescription bag and one prescription is filled in the container , you must state the expiry date on the prescription and collect them on a basket for the pharmacist to give out to customers.
