Travelling to the UK with diazepam: what changes

Diazepam, sold internationally as Valium, Diastat, and Stesolid, is a Schedule 3 controlled drug under the UK Misuse of Drugs Regulations 2001. Crossing the border with it requires a valid prescription and a supporting doctor's letter. No advance import licence is needed for personal quantities, but the documentation requirement is strict.^[1]

Medical disclaimer: This guide is for informational purposes only and does not constitute medical advice. Always consult your prescribing doctor before travelling with medication, particularly regarding supply quantities, storage requirements, and import documentation.

Before you travel

Documentation for travelling to the UK with diazepam

The UK Home Office recommends that travellers carrying controlled drugs carry a letter from their prescribing doctor. The letter should be on clinic letterhead and include your full name, medication name (diazepam and Valium), dose, frequency, quantity carried, and the prescriber's signature and registration number. No formal import licence is required for personal quantities of Schedule 3 drugs, but the letter is your primary protection at the border.^[2] Refer to our guide for travelling with benzodiazepines for more information on building your pre-travel documentation pack.

Because the UK's official language is English, no translation of your documentation is required. Notarisation or apostille is not a condition of entry for personal-use medication.

How much diazepam to bring

The UK Home Office guidance states that travellers may carry up to a three-month personal supply of controlled drugs without an import licence, provided they carry a doctor's letter. Bring at least 10% extra to account for delays or extensions. Do not rely on obtaining a local prescription quickly, as that process requires registration with a GP practice.^[2]

Packing and storing diazepam for travel

Diazepam tablets should be stored at room temperature below 25°C, protected from light and moisture. Standard cabin temperatures during flights are within this range, so no cold-chain equipment is needed. Keep tablets in the original blister packs inside a rigid carry-on case to prevent damage during transit.

At the airport and border

Airport security with diazepam

UK airport security is operated under rules set by the Department for Transport. Solid tablets do not count against the 100 ml liquid restriction, so diazepam tablets in blister packs pass through X-ray screening without special handling. You are not required to declare medication at the security lane, but having your doctor's letter accessible speeds up any secondary checks.

If screeners ask about the medication, state the generic name (diazepam) and show the pharmacy label. UK airport security follows Civil Aviation Authority guidance rather than IATA rules.^[3]

Customs and medication import rules for the UK

Diazepam is a Schedule 3 controlled drug under the Misuse of Drugs Regulations 2001. You do not need a formal import licence from the Home Office for a personal supply of up to three months. Border Force officers may ask you to produce your doctor's letter and prescription, so keep these in your hand luggage rather than checked bags. If you are entering via the red channel or are stopped for inspection, present both documents together.^[2]

While in country

Diazepam availability in the UK

Diazepam is widely available at NHS and private pharmacies across the UK. A UK prescription from a registered prescriber is required to dispense it, as it is a controlled substance. ^[4]

Without a UK prescription, a private GP consultation typically costs £60 to £120 (~$82 to ~$164). Generic diazepam tablets at a private pharmacy cost approximately £5 to £15 (~$7 to ~$20) for a short supply, depending on the dose.^[4]

Finding a doctor who can prescribe diazepam in the UK

As a short-term visitor, you are not entitled to free NHS primary care, but you can access private GP services at walk-in private clinics in all major UK cities. Diazepam is a controlled drug, so a new UK prescription requires an in-person consultation. Telemedicine services cannot prescribe Schedule 3 controlled drugs remotely in the UK. ^[5]

Private GP consultations in London typically cost £80 to £150 (~$109 to ~$205). Clinics such as those operated by major private hospital groups in London, Manchester, and Edinburgh all offer same-day or next-day appointments.^[5] See our United Kingdom healthcare guide for a broader healthcare context.

Storing diazepam while in the UK

The UK's temperate climate rarely exceeds 30°C, so standard room-temperature storage is suitable throughout the year. A bedside table drawer or a cool, dry hotel safe is adequate. No refrigeration or cooling wallet is required.

Emergencies

What to do if something goes wrong with your diazepam in the UK

If your medication is lost or stolen, report it to the local police immediately and obtain a crime reference number. Contact your travel insurer, then seek a private GP consultation with your crime reference number, your original prescription documentation, and your doctor's letter.

If you run out unexpectedly, a UK pharmacist can provide an emergency supply of a controlled drug only in very limited circumstances under the Human Medicines Regulations 2012. In practice, a private GP consultation is the fastest route. NHS A&E departments can assess and prescribe in urgent situations, but A&E is not a route for routine medication replenishment.^[6]

The emergency number for ambulance, police, and fire in the UK is 999. For non-emergency medical advice, call NHS 111, available 24 hours a day.
