- Reading and Checking: The prescription should be read and checked for legality, legibility, completeness, and correctness. This includes checking the physician’s details, patient’s details, and product details.
- Collecting and Weighing the Material: All the materials required for the prescription should be collected from the shelves or drawers and kept on the left-hand side of the balance. After measuring each material, it should be kept on the right-hand side of the balance.
- Compounding, Labelling, and Packaging: Only one prescription should be compounded at a time. Compounding should be done on a clean table. All equipment required should be cleaned and dried.
