This document discusses prescriptions and factors involved in prescribing medications. It defines a prescription as a document written by a doctor detailing a patient's medication. Prescriptions are not always necessary as some medications can be self-administered or over-the-counter. Whether a prescription is needed depends on doctor and patient factors. When prescribing, doctors consider a drug's effects, the patient's details, and ensuring no harm is done. Proper prescriptions include legible writing of patient details, diagnosis, drug name, dosage, and doctor's credentials. Explaining instructions clearly to patients can help maximize compliance.
