How to read the medicine name on a cancer prescription

Cancer prescriptions can contain long medicine names, a strength and instructions that are unfamiliar at first. This guide helps you identify the information to keep together; it does not explain which treatment is right for a patient.

Start with the generic medicine name

Look for the medicine name written by the clinician. It is often the most useful way to find reliable information, even when a brand name is also written on the prescription.

Do not substitute a similarly named medicine, change a dose or rely on a previous pack without speaking to the treating team.

Keep the strength and form together

A medicine name is incomplete without its strength and form. For example, a tablet strength may be written in milligrams. Keep a clear photo or copy of the prescription so the clinician’s instructions can be checked during any assessment.

Use the cancer type only as a starting point

Cancer type can make browsing less intimidating, but it cannot determine the right medicine. Diagnosis, test results, other medicines and the treating clinician’s judgement all matter.
