Chapter overview
A prescription is a written order from a registered practitioner to a pharmacist. This chapter explains its purpose and every part of it, from prescriber and patient details to the superscription, inscription, subscription and directions. It also covers legibility, the steps of handling and reviewing a prescription, and the common Latin terms and abbreviations used.
Key points on introduction to prescription
- A prescription is a legal document that instructs the pharmacist on the drug, dose, route and duration.
- The main parts are prescriber details, patient details, superscription (Rx), inscription, subscription and transcription (signa).
- The inscription lists the drug names and quantities, and the signa gives directions to the patient.
- Illegible or incomplete orders can cause dispensing errors, so clarity is essential.
- Latin abbreviations such as o.d., b.i.d., t.i.d., q.i.d., p.o. and s.o.s. must be read correctly.
Relevance to pharmacy practice
Reading and verifying prescriptions is the first duty of a dispensing pharmacist. Checking the dose, age of the patient, interactions and legal requirements before dispensing prevents errors and protects patients.
Every chapter in this subject builds on the one before it, so do not skip topics that look simple. Definitions, classifications and official examples are the parts that examiners return to most often, and a clear understanding here will also make later subjects such as pharmaceutics and pharmacology much easier to follow in the coming semesters.

Study and exam tips
Start by reading the chapter once for the overall idea, then revise introduction to prescription using headings, definitions, classifications and examples. Short-answer questions in the university exam usually ask for definitions, advantages, disadvantages and examples, so write these in your own words and practise drawing tables and flow charts where the chapter has them.
For wider reading, standard textbooks and open resources such as the NCBI Bookshelf help you confirm terms and see more worked examples. Revise introduction to prescription again a day later and again a week later, because spaced revision improves long-term memory.
