Travelling With Medicines From the Netherlands: CAK Certificates and a Packing Checklist

Reviewed 31 October 2026. Prices, fees and rules in this article were checked on 31 October 2026. They can change, so check the linked pages before you decide.

Travelling with medicines from the Netherlands can involve more than carrying a prescription. If your medicine falls under the Dutch Opiumwet, you need the appropriate certificate for your journey. The document depends on the medicine, destination and length of your stay. Start with NetherlandsWorldwide’s official guidance, then check the requirements for the countries on your route. This guide explains the paperwork for residents leaving the Netherlands; it does not determine whether a particular medicine is suitable for you.

1. Which document do you need?

There are three separate questions: is your medicine controlled under Dutch law, which travel certificate applies, and does the destination require additional formalities? A prescription or pharmacy printout does not answer all three. Use the CAK medicines travel checker for your own combination of medicine and journey.

2. Check the active ingredient

The CAK controlled-medicine guidance offers two ways to establish whether your medicine falls under the Opiumwet: use its travel checker or ask your doctor or pharmacist. The official lists use active ingredients, so have the ingredient name and dosage available rather than relying only on the brand printed on the box.

Government.nl’s examples include strong painkillers, certain sleeping and anxiety medicines, ADHD medicines and medicinal cannabis. These examples do not mean every medicine used for those conditions has the same status. Ask about your exact product. CAK also warns that a medicine may be treated as an opiate outside the Schengen area, making the destination’s own requirements relevant.

If you are still arranging routine care, our guide to finding a huisarts explains how to find and register with a practice. The travel-document question should go to the doctor or pharmacist who can check your medicine.

3. Arrange a Schengen certificate

For a journey requiring a Schengen certificate, the CAK Schengen application process begins with the travel checker. Complete its questions, download the prepared form and print it. Your doctor can complete missing medical information and must sign the document, add their BIG registration number and stamp it. CAK specifies an original handwritten signature.

Upload the completed, signed form using the linked CAK submission route. CAK checks the application and adds its approval stamp when everything is in order. It returns the approved document by email; print that version and take it on your journey. A downloaded application form is therefore not the same as an approved certificate.

The same page says one certificate covers 30 days, and longer journeys require additional certificates. However, CAK’s English-language guidance also identifies trips exceeding 90 days as a separate case. For an extended stay, use the checker instead of assuming that repeating the short-trip process is always sufficient. These durations were checked on 31 October 2026.

4. When the English-language route applies

CAK’s English-language certificate page directs travellers taking controlled medicines outside Schengen, or travelling for longer than 90 days, to the English-language certificate route. The current process is different from uploading a Schengen form. Its five-step process says to print and complete the form, obtain your doctor’s signature, then submit it by post or bring it to the CAK desk as directed for your departure timing.

CAK approval may be followed by another authentication step. The English-language page explains that an apostille-country destination can involve a court stamp; other destinations may involve an embassy, consulate or the Ministry of Foreign Affairs. Ask the destination’s embassy or consulate which sequence applies. NetherlandsWorldwide’s legalisation guidance likewise bases the legalisation route on both the document and the country where it will be used.

Do not treat the words “English-language certificate” as universal permission to carry every medicine anywhere. The destination check remains part of the process. These procedural rules were checked on 31 October 2026.

5. Include transit countries

A connection is part of your document planning. CAK’s transit guidance distinguishes staying within the airport’s customs area from entering the connection country. It says a certificate valid for that country is needed if you visit it, including when you pass through customs and later check in again.

For journeys by car, train, bicycle or another overland method, CAK says the documents must be valid for the countries you travel through. Its detailed guidance also distinguishes routes inside and outside Europe. Do not infer the answer solely from your final destination or from an airline’s description of a transfer.

Record every country and whether you will enter it, then use the checker for that itinerary. For mixed routes, ask CAK which certificates are required rather than assuming one document covers every leg. Transit guidance was checked on 31 October 2026.

6. Plan around the published processing guidance

NetherlandsWorldwide advises starting at least four weeks before travel. There is a difference between CAK’s published Schengen pages: its download instructions say to upload no later than four weeks before departure, while its timing FAQ says preferably one week before departure. That FAQ still specifies at least four weeks for the English-language certificate sent by post.

For planning, allow at least four weeks and confirm the current instructions for your document. The shorter wording on one FAQ is not a reason to assume your own application will be approved within a week. Leave time for your doctor’s signature and any further stamps. These published timings were checked on 31 October 2026.

7. If departure is close

CAK’s urgent-departure page tells travellers without a certificate to use the checker and obtain the required doctor’s signature and CAK approval. For departure within 24 hours, it describes bringing the completed, signed certificate to its office in The Hague. The stated counter hours are weekdays from 09:00 to 12:00.

If you submitted digitally and have received no reply 24 hours before departure, the same page says to call 0800-2108 on weekdays between 08:30 and 17:00, with the reference number from your confirmation email available. These hours and contact details were checked on 31 October 2026. Confirm them on the linked page before travelling to the office. This is not a promise of weekend processing or automatic approval.

8. Pack medicines and documents together

Douane advises carrying medicines in their original packaging and in hand baggage so you can show what you are carrying during checks. Keep the approved certificate available with them. A medication overview can help a clinician understand your treatment if you need care abroad, but serves a different purpose from border paperwork.

For the return journey, Douane says the certificate obtained in the Netherlands can also be used when bringing back the same medicines. Medicines prescribed abroad can require a different document or legalisation check. This guide’s outbound process should not be assumed to cover a new prescription obtained during your stay.

These customs rules were checked on 31 October 2026. For the rest of your airport planning, see our Schiphol Airport guide; its transport and security information is separate from the medicine-certificate process.

9. Your pre-departure checklist

Use this as a personal preparation list alongside the linked official instructions. It combines the steps above; it is not an application form or a certificate.

• Write down the medicine’s active ingredient, dosage, travel dates and all destination and transit countries.
• Ask your pharmacist or doctor about controlled status and complete the CAK checker.
• Arrange the correct form, doctor’s signature and CAK approval.
• Confirm any embassy, consular, court or legalisation steps for the itinerary.
• Print the approved document where required and pack it with the original medicine packaging.
• Keep a medication overview separately useful for medical care, and retain the CAK application reference until the process is complete.

10. FAQ

Is my medication passport enough?

No, if a travel certificate is required. CAK says a medication passport or overview is useful if you lose medicines or need a doctor, but does not replace the controlled-medicine paperwork. Ask for both documents when they serve different needs.

Does my child need the paperwork too?

Government.nl explicitly includes a child’s controlled medicines in its Schengen certificate guidance. Check the child’s actual medicine and trip rather than assuming an adult’s document covers the family. The requirement was checked on 31 October 2026.

Can I use this guide for a medicine that is not controlled in the Netherlands?

Use the destination check. NetherlandsWorldwide directs travellers with medicines outside the Opiumwet to the destination country’s embassy or consulate in the Netherlands. Dutch classification alone does not settle what another country permits.
