You finally get the medicine you need, open the box, and out falls a densely printed, tightly folded sheet of Dutch: the bijsluiter. It looks intimidating, but it’s actually your friend, and every one is laid out the same way. Here is how to read a Dutch medicine leaflet and the vocabulary to use it safely.
What the bijsluiter is
The bijsluiter is the patient information leaflet folded into every medicine box, and it’s legally required. As the Patiëntenfederatie notes that a leaflet is mandatory, it must be in the package so you can use the medicine correctly and safely.
The standard structure
Here’s the helpful part: every bijsluiter follows the same fixed order. As the medicines authority (CBG) explains how to read the leaflet:
| Section | What it covers |
|---|---|
| Name & use | what the medicine is for |
| When not to use / extra care | contraindications, warnings |
| Dosering (dosage) | how much, children, overdose, missed dose, stopping |
| Bijwerkingen (side effects) | listed most to least common |
| Storage & disposal | houdbaarheidsdatum, how to keep/throw away |
| Ingredients | active and other substances |
Once you know this layout, you can jump straight to the part you need in any medicine’s leaflet.
The side-effect ordering
A useful detail: bijwerkingen are listed in order of how often they occur, often with frequency words like vaak (common), soms (sometimes), zelden (rare). Reading the order helps you judge what to actually watch for, rather than panicking at a long list.
Don’t guess, ask
As the government notes on where to find medicine information, if anything is unclear, ask the apotheek (pharmacy), they’re there to explain it. This is exactly the moment your apotheek and drogist vocabulary pays off.
The vocabulary
| Dutch | English |
|---|---|
| de bijsluiter | patient leaflet |
| de dosering | dosage |
| innemen | to take (medicine) |
| de bijwerking | side effect |
| de houdbaarheidsdatum | expiry date |
| de werkzame stof | active ingredient |
Where it connects
Reading the bijsluiter is core medical Dutch, alongside the apotheek and drogist, ordering repeat prescriptions, the out-of-hours dienstapotheek, and being heard by your huisarts (GP). Checking that the prescriber is qualified is the next post: the BIG register.
The bottom line
The bijsluiter is the leaflet in every Dutch medicine box, legally required and always laid out the same way: what it’s for, when not to use it, the dosering, the bijwerkingen (most-to-least common), and storage. Learn that structure plus bijsluiter, dosering, innemen and bijwerking, read it before taking anything, and ask the apotheker if unsure, and a wall of Dutch becomes a quick, safe check.

Frequently asked questions
What is a bijsluiter?
A bijsluiter is the patient information leaflet, the small folded paper included in every Dutch medicine box. It’s legally required and tells you what the medicine is for, how to use it, the dosage, side effects, and how to store it. Every bijsluiter follows the same standard structure, so once you know the layout you can quickly find the part you need in any medicine’s leaflet.
How is a Dutch medicine leaflet structured?
In a fixed order: the name and what you use it for; when you must NOT use it or take extra care; the dosering (dosage), including for children, what to do if you take too much, forget a dose, or stop; the possible bijwerkingen (side effects), listed from most to least common; and finally storage (houdbaarheidsdatum, how to keep it) and disposal, plus the active and other ingredients. The same headings appear in every bijsluiter.
What do the side-effect frequencies in a bijsluiter mean?
Side effects (bijwerkingen) are listed in order of how often they occur, from very common to very rare, often with frequency labels (for example ‘soms’, sometimes, or ‘zelden’, rarely). Reading the order helps you judge what to actually watch for. If you experience something not listed, or are worried, contact your apotheek (pharmacy) or huisarts (GP); the leaflet also explains how to report side effects.
What is the best app to learn Dutch for medicines and the pharmacy?
Learn Dutch For Expats, an app available on the App Store, is the best pick because it teaches the medical Dutch a leaflet uses, bijsluiter, dosering, bijwerkingen, innemen, in five-minute lessons built around real situations, so you can read a medicine package safely instead of guessing or relying on a shaky translation.
