Can You Travel Home With Prescription Medicines After Treatment?

Usually, if prescribed and documented. Controlled drugs such as tramadol or codeine go in hand luggage with proof of prescription and up to 3 months' supply.

Short answer

Usually yes, but the rules depend on whether a medicine contains a controlled drug. Strong painkillers often given after surgery, such as tramadol, codeine and oxycodone, are controlled drugs in the UK.3 Controlled medicines must travel in your hand luggage, you must be able to prove they were prescribed for you, and you can bring no more than three months’ supply; UK residents prescribed medicine abroad are told to contact the Home Office Drug and Firearms Licensing Unit.1 Rules in the country you are leaving also apply.2

Key points

  • Medicines containing a controlled drug must be carried in hand luggage when entering or leaving the UK.1
  • Medicine may be taken away at the border if you cannot prove it was prescribed for you.1
  • Keep medicines in original, labelled pharmacy packaging with a copy of the prescription and a doctor’s letter.2
  • Check the exporting country’s rules with its embassy; some require an export licence for controlled drugs.2
  • Avoid buying medicines informally abroad because of the risk of falsified products.24

First, find out whether the medicine is controlled

Controlled drugs are medicines regulated under UK misuse of drugs law because they can cause dependence or be misused. Many medicines commonly prescribed around surgery fall into this group. The Home Office list includes tramadol, codeine, dihydrocodeine, oxycodone and morphine (opioid painkillers), diazepam (a sedative), and pregabalin and gabapentin (nerve-pain medicines).3

Many other medicines given after surgery are not controlled. The Home Office list names drugs, not brand names, so the GOV.UK guidance suggests asking a doctor or pharmacist whether a particular medicine contains a controlled drug.1

Bringing controlled medicines into the UK

GOV.UK sets out the main rules.1

  • Carry the medicine in your hand luggage, not in checked baggage.
  • Be able to prove it was prescribed for you; otherwise it may be taken away at the border.
  • Bring no more than three months’ supply. Larger amounts, or medicine sent by post, will be taken away; a personal licence may be possible in exceptional circumstances.
  • If you are a UK resident who has been prescribed medicine while abroad, contact the Drug and Firearms Licensing Unit (DFLU), the Home Office team that handles these licences.

For people who are not UK residents, GOV.UK says the prescriber’s letter should include your name, your travel dates, a list of the medicines with amounts, doses and strengths, and the prescriber’s signature.1 Asking the treating clinic for a letter with these details is sensible for anyone, and contacting the DFLU before you fly home avoids surprises at the border.

Leaving the country where you were treated

The country you fly out of has its own rules. The National Travel Health Network and Centre (NaTHNaC) advises checking regulations on transporting medicines with the relevant embassy or high commission, and notes that controlled drugs may need an export licence for certain quantities.2 Ask the treating clinic how this applies to the medicines it has prescribed, and check with the embassy if you are unsure.

Practical packing and paperwork

  • Keep medicines correctly labelled in original pharmacy packaging.2
  • Carry a copy of the prescription and a covering letter from the doctor.2
  • Pack enough for the whole journey, with allowance for delays.24
  • Check airline rules for liquid medicines, which have hand-luggage limits.2
  • If you need to take medicines during the flight, take them yourself: cabin crew are not trained to give medication.6

If you are sent home with blood-thinning injections to prevent clots, UK guidance says you should know how to use them, for how long, and who to contact with problems.5 Make sure this is in writing, along with the rest of your records to bring home.

Buying extra medicines abroad

It can be tempting to stock up locally. NaTHNaC warns about falsified medical products and advises getting the medicines you need before travelling where possible.2 The US Centers for Disease Control and Prevention (CDC) adds that some medicines abroad may be counterfeit or ineffective because of contamination, expiry or poor storage.4 Medicines prescribed by the treating team for your recovery are a different matter from buying extra supplies informally.

Common questions

Can I put my painkillers in my suitcase?

Not if they contain a controlled drug: these must be in hand luggage when entering or leaving the UK.1 For other medicines, NaTHNaC suggests hand luggage with some extra in the hold.2

Do antibiotics need a letter?

Whether or not a medicine is controlled, a prescription copy and a doctor’s letter are recommended for any medicines you travel with.2

What if my medicine is taken at the border?

Contact your GP promptly so treatment, especially pain relief or blood thinners, is not interrupted. Proof of prescription reduces the chance of this happening.1

Bottom line

Most post-operative medicines can travel home with you if they are prescribed, labelled and documented. Strong painkillers and some other medicines are controlled drugs, so check the UK rules and the exporting country’s rules before you fly.
