Three principles cover almost every situation.
- Carry more than you think you need. Plan for the trip plus an extra week. Flights get cancelled, plans extend, and a small buffer prevents most of the problems that bring people to this website.
- Keep medication in original packaging. A loose pile of pills in a daily organiser is fine for the flight, but the labelled blister packs and boxes should travel with you too. They prove what the medication is and who prescribed it.
- Bring documentation. A copy of your most recent prescription, or the GP printout that lists all your active medications, fits on a single page and answers most questions a pharmacist or customs officer will ask.
- Full course of medication for the trip, plus at least one extra week
- Original boxes and blister packs (the prescription label matters)
- A printed list of medications, doses, and what each is for
- Your GP's name, surgery, and a contact phone or email
- The NHS app installed and logged in on your phone
- For controlled drugs only: a Schengen certificate (see below)
- Your EHIC, GHIC, or travel insurance documentation
For personal-use quantities of normal prescription medication in original packaging, Spanish customs will not normally stop or question you. Spain follows standard European rules for travellers carrying their own medication.
What "personal-use quantity" means in practice: enough for your trip, with a reasonable buffer. If you are travelling for two weeks with two months of medication, that's still fine - but if you are travelling for two weeks with two years' supply, customs may have questions.
The simple safeguard: pack the medication in the original box with the label, and carry a copy of your prescription. If you are questioned, this is the documentation that resolves things in under a minute.
If you take a controlled medication - strong opioid painkillers, ADHD stimulants, benzodiazepines, sleeping tablets, certain anti-anxiety medications, or any drug in the UK Misuse of Drugs Act schedules - the rules are stricter.
For travel within the Schengen area (which includes Spain), you may need a Schengen certificate. This is issued in the UK by your GP or specialist and confirms that the controlled medication you are carrying is prescribed for your personal use. The certificate must be obtained before you travel - Spanish customs cannot issue one retrospectively.
Practical thresholds:
- Trips of fewer than 30 days - many travellers carrying smaller quantities of controlled drugs travel without a Schengen certificate, in original packaging with a copy of the prescription. This is at your own risk, and a certificate is the safer route.
- Trips of 30 days or more, or larger quantities of controlled medication - a Schengen certificate is strongly recommended. Some sources treat it as required.
- If in any doubt - ask your GP for one. They are usually issued within a week or two; some surgeries charge a small fee.
The Holiday Doctor does not issue, replace, or top up controlled medications under any circumstances. If you forget your Schengen certificate or your controlled medication gets lost in Spain, the right route is the Spanish public system (Centro de Salud or Urgencias), not an online consultation.
Always carry essential medication in your hand luggage, not in the hold. Checked bags get lost, delayed, or arrive at the wrong airport. The flight is the moment most medications get separated from the people who need them.
Most airlines allow medication and medical equipment as essential items, exempt from the standard hand-luggage allowance. Liquid medications, including insulin, can be carried in volumes above 100ml provided they are declared at security with documentation. Carry the prescription label or a letter confirming the medical need.
For sharps (insulin pens, needles, EpiPens), carry the prescription documentation and declare them at security. They are routinely allowed.
Insulin and other temperature-sensitive medications need a cool-pack or insulated bag for longer flights. Most airlines will help store medications in their galley fridges if you ask the cabin crew on boarding. For a fuller checklist, see our guide on flying to Spain with insulin and medication.
Two scenarios to plan for.
- Luggage delayed. File a Property Irregularity Report (PIR) at the airport before leaving the baggage hall. The airline is responsible for funding emergency purchases including medication. Keep all receipts.
- Luggage lost or stolen. Same PIR. Notify your travel insurance immediately. Most policies cover lost prescription medication.
For most non-urgent medications, your home pharmacy can post a refill by next-day delivery to a Spanish address. For urgent medications, an online consultation with a Spanish prescriber may be faster.
For longer stays, or if your supply runs short, there are three routes:
- The public system (Centro de Salud) - accessible with an EHIC, GHIC, or Spanish tarjeta sanitaria. Realistic wait times vary.
- A private GP in person - same-day availability, EUR 50 to 120, English-speaking clinicians are common in cities and coastal areas.
- An online private consultation - for in-scope medications where your history can be reviewed remotely, often the fastest route.
The Holiday Doctor service is built for the third of these. Our consultation form will tell you immediately, at no charge, whether your medication is within our scope.
Two things travel insurance commonly covers:
- Replacement of lost medication abroad, if the loss was unforeseen. Keep all receipts and any documentation from the consultation.
- Medical care abroad, including consultations, hospital stays, and repatriation if needed.
Two things it commonly does not:
- Routine repeat prescriptions that could have been arranged before the trip.
- Medication for pre-existing conditions that were not declared when the policy was bought.
The UK GHIC (replacing the old EHIC for most UK travellers since Brexit) provides access to the Spanish public healthcare system on the same terms as a Spanish citizen. It is not a substitute for travel insurance - it does not cover repatriation, private care, or much of what insurance is actually for - but it is free and worth having.
Important. The Holiday Doctor does not assess or prescribe controlled drugs, weight-loss medication, anti-coagulants, complex psychiatric regimens, or new conditions outside our published scope. For any of these, the right route is the Spanish public system or a private GP in person.
