You need to prove medicine belongs to you if:

  • it contains a controlled drug
  • you have it on you when you’re entering or leaving the UK

You may also need to get a licence.

Check if your medicine contains a controlled drug

Check the drugs listed on the packaging of your medicine and search for them on the controlled drugs list. The list doesn’t give names of medicines, only drugs that are used in medicines.

You’ll need to prove you own medicine that contains a drug listed as schedule 2, 3 or 4 on the controlled drugs list.

Drugs may have different schedules depending on the dose.

You’ll need to write a proof of ownership letter to prove you own the drugs. You might need to show this at the border.

The letter must include:

  • your name
  • what countries you’re going to and when
  • a list of your medicine, including how much you have and doses
  • the signature of the person who prescribed your drugs

When you need a licence

You’ll need to apply for a licence if you’re either:

  • travelling for 3 months or more
  • carrying a supply of medicine that would last you 3 months or more

How to apply for a licence

Fill in the application form and send it with your proof of ownership letter to the address on the form.

You should apply at least 10 working days before you’re due to travel. Applications from outside the UK could take longer.
