People use medicine and medication as if they were the same word, and in many sentences they are. The difference is that medicine has two meanings and medication has one. Medicine is the science and practice of treating disease, and it is also a substance you take to get better. Medication only means the substance, or the treatment given with it.

So every medication is a medicine, but medicine is also the name of a profession, a degree and a body of knowledge.

Medicine: two meanings in one word

The first meaning is the field. A student studies medicine. A doctor practises medicine. Internal medicine, emergency medicine and sports medicine are branches of it. You cannot replace the word with medication in any of these phrases.

The second meaning is the thing you swallow, inject, inhale or apply. "Take your medicine" and "this medicine may cause drowsiness" use the word this way. It is the ordinary, household word, and the one most people use with children.

Medicine also stretches beyond drugs. People speak of herbal medicine, traditional medicine and preventive medicine, and say that laughter is the best medicine. Medication is not used in these wider or figurative ways.

Medication: the clinical word for drug treatment

Medication is narrower. It means a drug used for a medical purpose, usually one that has been prescribed or recommended. Health professionals prefer it because it is exact. A hospital chart has a medication list. A pharmacist carries out a medication review. Giving the wrong drug or dose is a medication error.

The word also names the state of being treated. "She is on medication for blood pressure" does not point to one tablet. It says that drug treatment is under way.

Where does "drug" fit?

Drug is the widest of the three words. In pharmacology, a drug is any substance that changes how the body works. That includes medicines, and it also includes caffeine, alcohol, nicotine and illegal substances. In United States law, the Food and Drug Administration treats as a drug any article intended to diagnose, cure, mitigate, treat or prevent disease.

In everyday speech the word drug often suggests misuse, which is one reason patients are usually told about their medicines or medications. Among professionals, drug is neutral and common, as in drug interaction or drug dose.

WordCoversExample
DrugAny substance that acts on the body, helpful or harmfulCaffeine is the most widely used drug in the world.
MedicineA drug or preparation used to treat or prevent illness, and the field itselfKeep all medicines out of reach of children.
MedicationA medicine as part of someone's treatmentBring a list of your current medications to the clinic.

British and American habits

Both words are correct in every variety of English. There is a difference in habit. British health services tend to say medicines, as in the NHS "Medicines A to Z". American clinicians and pharmacies tend to say medications, often shortened to meds. Neither choice is wrong, and readers in both countries understand both.

Grammar: countable or not?

  • Medicine as the field is uncountable. You study medicine, never "a medicine".
  • Medicine as a substance can be either. "Take some medicine" is uncountable. "Three different medicines" counts types.
  • Medication works the same way. "He is on medication" is uncountable. "He takes four medications" counts them.

Which word should you use?

  • Talking about the profession, a degree or a specialty: use medicine.
  • Talking to patients, families or children: medicine is warmer and clearer.
  • Writing clinical notes, exam answers or care plans: medication is the standard term.
  • Writing about how a substance acts in the body: drug is the scientific term.

Prescription and over-the-counter medicines

Both medicine and medication can be used for products bought with or without a prescription. A prescription medicine needs authorisation from a doctor or other prescriber. An over-the-counter medicine can be bought directly. In the United Kingdom there is a middle group, pharmacy medicines, which are sold without a prescription but only under a pharmacist's supervision.

Each medicine also has two kinds of name. The generic name identifies the active ingredient, such as paracetamol or ibuprofen. A brand name is chosen by the manufacturer. Clinicians are taught to use generic names because they are the same everywhere.

Common mistakes for learners of English

Speakers of Spanish, French, Italian and Portuguese often choose medication because it resembles "medicamento" or "medicament" in their own languages. In English, medicine is the more common everyday word.

What style guides prefer

Writing guidance for patient information generally favours the plainest word. The National Health Service in England uses medicine in its public content and avoids drug where it could suggest illegal substances. Clinical journals and hospital policies in North America more often use medication. If you write for patients, choose medicine. If you write for a clinical audience, follow the house style of the journal or hospital.
