How to Read a Prescription Label

When you collect a prescription, the pharmacy label is the most important piece of paper in the bag. It tells you what the medicine is, who it is for and how it should be taken. Yet the print is small, the layout varies from one pharmacy to the next, and it is easy to glance at it once and put it away.

This guide walks through the parts you will usually find on a label. It does not give advice about any particular medicine or amount. Your pharmacist and the person who prescribed the medicine are the right people to ask about your own treatment.

The parts of a typical label

Layouts differ between countries and pharmacies, but most labels include the same core information.

Part of the label	What it tells you	What to check
Your name	Who the medicine was dispensed for	That it is your name, spelled correctly
Medicine name	The brand name, the generic name or both	That it matches what your prescriber told you
Strength and form	How much active ingredient is in each tablet, capsule or measure, and whether it is a tablet, liquid, cream and so on	That it matches the prescription; ask if it looks different from last time
Directions	How much to take, how often and sometimes for how long	That you understand them before you leave
Quantity	How many tablets or how much liquid is in the pack	That it looks right for the length of the course
Date dispensed	When the pharmacy prepared it	Helpful when you are tracking repeats
Prescriber	Who wrote the prescription	Useful if you need to ask a question later
Pharmacy details	Where it was dispensed	Keep these so you know who to call

In some countries the label also shows a prescription number, the number of refills left or a date after which the medicine should not be used.

Reading the directions carefully

The directions line is where misunderstandings happen most. A few phrases are worth slowing down for:

• "Twice a day" or "every twelve hours". These can mean slightly different things. Ask whether timing matters for your medicine.
• "With food" or "on an empty stomach". Some medicines work better or cause fewer side effects depending on meals.
• "As needed" or "when required". Ask what the most you should take in a day is, and how long to wait between doses.
• "Until finished". This means completing the course, even if you feel better earlier.

If any wording is unclear, ask the pharmacist to explain it in plain words before you leave the counter. Writing the answer on the box can help later.

Warning stickers and extra labels

Many pharmacies add small coloured stickers or printed warnings. Common examples include advice not to drive if the medicine makes you drowsy, to avoid alcohol, to avoid certain foods or drinks, to keep the medicine in the fridge, or to shake a liquid before use. These are there for a reason, so read each one and ask if it does not make sense for you.

The leaflet inside the box

Alongside the label, most medicines come with a patient information leaflet from the manufacturer. It covers what the medicine is for, possible side effects, how to store it and what to avoid. The label is specific to you; the leaflet is general. If they ever seem to say different things, follow the label and check with your pharmacist.

Questions worth asking at the pharmacy

1. What is this medicine for, and how will I know it is working?
2. When and how should I take it, and what if I miss a dose?
3. Are there foods, drinks or other medicines I should avoid with it?
4. Which side effects are common, and which mean I should get help?
5. How should I store it, and what should I do with any left over?

Pharmacies increasingly share information in other ways too, from printed cards to screens in the waiting area; our article on digital signage in pharmacies looks at that side of the visit.

Keeping track at home

• Keep medicines in their original labelled containers, out of sight and reach of children.
• Do not share prescription medicines, even with someone who seems to have the same symptoms.
• Keep an up-to-date list of everything you take, including over-the-counter products and supplements, and bring it to appointments.
• Return unused or out-of-date medicines to a pharmacy rather than throwing them in the bin.

When to get help

Contact your pharmacist or the prescriber if the label does not match what you were told, if the tablets look different from your usual supply, if you think you have taken too much or the wrong medicine, or if you have side effects that worry you. In an emergency, such as trouble breathing, swelling of the face or a severe reaction, call your local emergency number straight away.

Never change or stop a prescribed medicine on your own based on the label alone. A two-minute conversation with your pharmacist is usually the quickest way to clear up any doubt.
