Generic Medication in Spain: EFG Guide & Prices (2026)
Generic Medication in Spain: The Complete Guide to EFG Medicines, Prices and Substitution
A month of generic omeprazole costs about €2.42 in a Spanish pharmacy. The same active ingredient, made to the same standards as the brand — for less than the price of a coffee and a croissant. Here's how Spain's generic system works, and how to use it.

If you take regular medication and you're spending any real time in Spain — a winter in the Canaries, a semester in Granada, a new life on the coast — the generic system is the single most useful thing to understand about Spanish pharmacies. It is why your monthly medication bill here may be a tenth of what it was at home.
Spain's approach is unusually tidy. Generics carry a legal designation printed on the box, prices are set nationally by the government, and pharmacists follow written rules about when they can and cannot swap one product for another. Once you know the system, there are no surprises at the counter.
This guide covers what the EFG label guarantees, real 2026 prices with US and UK comparisons, the laws that govern substitution at the counter, and how to find the Spanish generic name for the medication you take at home.
What Does EFG Mean on a Spanish Medicine Box?
EFG stands for Equivalente Farmacéutico Genérico — generic pharmaceutical equivalent. The three letters appear on the packaging of every authorised generic medicine in Spain. If a box says EFG, the product contains the same active ingredient, in the same dose and pharmaceutical form, as the original reference medicine, and has demonstrated bioequivalence to it.
Spanish law defines a generic precisely. The consolidated medicines act (Real Decreto Legislativo 1/2015, Article 2) describes it as a medicine with "the same qualitative and quantitative composition in active ingredients and the same pharmaceutical form" as a reference medicine, "whose bioequivalence with the reference medicine has been demonstrated by appropriate bioavailability studies".
Naming follows a simple pattern: active ingredient + manufacturer + EFG. So you'll see omeprazol cinfa EFG, atorvastatina normon EFG, sertralina teva EFG. The manufacturer name (Cinfa, Normon, Teva, Kern Pharma, Stada, Sandoz and a handful of others dominate Spanish shelves) is just the lab; the medicine is defined by the ingredient before it.
One label worth distinguishing: EFP (Especialidad Farmacéutica Publicitaria) marks non-prescription medicines that can be advertised to the public. EFG and EFP are unrelated — one is about generic status, the other about prescription status. A generic can be prescription-only, and most are.
Are Generic Medicines in Spain as Good as Brand-Name?
Yes. Generics in Spain are authorised by the Spanish Medicines Agency (AEMPS) or the European Medicines Agency under the same quality, manufacturing and pharmacovigilance standards as originals. Before authorisation, each generic must prove bioequivalence — that it delivers the active ingredient into the bloodstream at the same rate and extent as the reference product.
The bioequivalence requirement is where a persistent myth comes from. You may have heard that generics "can differ by 20%". That is a misreading of the statistical acceptance range used in bioequivalence studies, which is the standard applied worldwide — including to different batches of the original brand itself. As the Spanish generics association AESEG puts it, generics do not contain less active ingredient; the figure refers to normal variability in absorption between individuals, which applies to every medicine, branded or not.
In practice, the factories are often the same. Many Spanish generics are produced in the same plants, to the same European Good Manufacturing Practice standards, as branded equivalents. AEMPS inspects generic and brand manufacturers identically.
In our consultations, we prescribe by active ingredient as a matter of routine, and we see no clinical difference in outcomes between patients taking generics and those taking originals. Where we do take care is with a small group of narrow-margin medicines — more on that in the substitution section below, because Spanish law treats them differently too.
How Much Cheaper Are Generics in Spain?
Spanish generics typically cost 40–60% less than the original brand did before generic competition, according to AESEG, and the absolute prices are low by any international standard: a month of a common generic often costs €2–8 at full retail price, without any insurance or subsidy. There are no tourist prices — the government-set price is the price.
Here is what that looks like for common long-term medications, comparing the full Spanish retail price (PVP, the government-regulated pharmacy price) with what a cash payer faces in the US and the flat NHS charge in England:
| Medication (generic) | Spain — full price | US — cash price | England — NHS charge |
|---|---|---|---|
| Omeprazole 20 mg × 28 | €2.42–2.50 | ~$15–25 (est.) | £9.90 per item |
| Atorvastatin 20 mg × 28–30 | €7.20–8.18 | $60.96 avg. retail (30 tabs) | £9.90 per item |
| Amoxicillin 500 mg (course) | ~€2–4 (est.) | ~$10–30 (est.) | £9.90 per item |
| Metformin 850 mg × 50 | ~€2–3 (est.) | ~$10–20 (est.) | £9.90 per item |
| Sertraline 50 mg × 30 | ~€3–6 (est.) | ~$15–40 (est.) | £9.90 per item |
Verified figures: Spanish omeprazole and atorvastatin prices are the actual financed retail prices listed in Spain's official pricing nomenclature in 2026; the US atorvastatin figure is GoodRx's reported average retail price for thirty 20 mg tablets (May 2026); the NHS England prescription charge is £9.90 per item, frozen again for 2026. Rows marked "est." are typical ranges — the exact Spanish PVP depends on the manufacturer and pack size, but stays within a euro or two of these figures.
Two things stand out. First, in Spain the medicine itself is often cheaper than the NHS's dispensing charge in England — the £9.90 flat fee exceeds the full Spanish retail price of most generics on this table. Second, the US comparison isn't close even with discount coupons: brand-name Lipitor still lists at around $190 per month discounted in the US, against €7–8 for the identical molecule in Spain.
How Spain Keeps Generic Prices Low: The Reference Price System
Spain caps what medicines can cost through a reference price system, regulated by Real Decreto 177/2014. Once a generic exists, all interchangeable versions of a medicine — same active ingredient, same route of administration — are grouped together, and the state sets a reference price for the group based on the lowest-cost versions in it.
The practical effect: brand and generic prices converge. The original manufacturer can keep selling above the reference price only outside public funding, so most brands drop their Spanish price to match the reference level. This is why the gap between brand and generic at a Spanish pharmacy counter is often small or zero — the system has already extracted the saving for you, whichever box you're handed.
It is also why Spanish prices are stable. The PVP — precio de venta al público, the retail price including the pharmacy margin and VAT — is printed into the national pricing database, updated by ministerial order, and identical in every pharmacy in the country, from central Madrid to a village in Extremadura. Pharmacies cannot discount prescription medicines, and they cannot mark them up.
Seen from abroad, the results are striking but the trade-offs are real: Spain's generic market share is around 40% of packs dispensed but only about 21% by value, well below the EU average of roughly 65% by units, and manufacturers periodically warn that rock-bottom reference prices push some low-margin products off the market. As a patient, though, you are on the winning side of that bargain.
Can the Pharmacist Swap Your Brand for a Generic?
Sometimes — and the rules are written into law, not left to the pharmacy's discretion. Under Article 89 of Real Decreto Legislativo 1/2015, a pharmacist dispenses exactly what is prescribed, but may substitute an equivalent medicine of the same or lower price when the prescribed product is unavailable or in cases of urgent need, informing the patient and noting the change.
Within the public system, most prescriptions are written by active ingredient rather than brand (prescripción por principio activo, required as the general rule by the same consolidated act). When the prescription names only the ingredient, the pharmacy dispenses one of the lowest-priced interchangeable products — which may be a generic or a price-matched brand. That is not really "substitution"; it is the system working as designed.
Some medicines can never be swapped at the counter. An exceptions list (Orden SCO/2874/2007, updated by AEMPS resolutions) protects products where small differences could matter clinically — including biological medicines, narrow therapeutic margin drugs, and certain inhaled respiratory products. For those, the pharmacy must dispense the exact product prescribed, full stop.
In our consultations with patients switching between UK, US and Spanish supplies of the same medicine, the substitution question comes up constantly. Our advice is always the same: what matters is the active ingredient and dose staying constant, except for the narrow-margin group above, where the exact product should stay constant too. If you're unsure which group your medicine falls into, ask — it takes a doctor thirty seconds to tell you.
Your Medication's Spanish Name: US/UK Brands and Their Generic Equivalents
The fastest way to get the right medicine in Spain is to know the active ingredient, because Spanish generic names are simply the ingredient's international name with Spanish spelling. Brand names change at borders; the molecule doesn't. Check the small print on your box at home — the ingredient is always listed under the brand.
| US / UK brand | Active ingredient | Typical Spanish generic name |
|---|---|---|
| Lipitor | atorvastatin | atorvastatina + lab name, EFG |
| Prilosec / Losec | omeprazole | omeprazol + lab name, EFG |
| Zoloft / Lustral | sertraline | sertralina + lab name, EFG |
| Glucophage | metformin | metformina + lab name, EFG |
| Augmentin | amoxicillin + clavulanic acid | amoxicilina/ácido clavulánico EFG |
| Ventolin | salbutamol (US: albuterol) | Ventolin also sold in Spain; generic salbutamol |
| Tylenol / Panadol | paracetamol (US: acetaminophen) | paracetamol — many labs, pharmacy shelf staple |
| Advil / Nurofen | ibuprofen | ibuprofeno — 600 mg is prescription strength in Spain |
Note the false friends. American "albuterol" is salbutamol everywhere in Europe; "acetaminophen" is paracetamol. And note the direction of surprise: ibuprofen 600 mg, handed out like sweets in some countries, is prescription-only at that strength in Spain, while the 400 mg strength is freely sold.
How to Ask for Generics in a Spanish Pharmacy
You rarely need to ask. With a Spanish prescription written by active ingredient, the pharmacy gives you a low-priced version automatically. For over-the-counter medicines, one phrase does the work: "¿Tiene el genérico?" — do you have the generic? — or "el más barato, por favor" — the cheapest one, please.
A few practical realities of the counter:
- OTC prices are not regulated the way prescription prices are, so the same ibuprofen 400 mg can cost €2 as a generic or €6 as a heavily advertised brand on the same shelf. Asking for the generic is where the saving lives.
- Pack sizes are fixed. Spain sells medicines in authorised pack sizes (28 tablets, not a bottle counted out to 90). If you need three months' supply, that's three boxes, and the prescription must cover it.
- The pharmacist is a clinician. Spanish pharmacies are owner-run by pharmacists, and minor-ailment advice at the counter is normal and free. They cannot, however, hand over prescription medicines without a prescription — and since electronic prescribing became universal, the informal flexibility older guides mention has largely disappeared.
In our consultations, the question we hear most from newcomers is some version of "will the pharmacy just give me my usual tablets if I show them my old box?" The honest answer: for anything prescription-only, no — not any more. What they will do is tell you the Spanish equivalent exists and costs €3, at which point you need a Spanish prescription to unlock it.

Visitors and most new arrivals pay the full retail price — the PVP — for prescription medicines, with no subsidy. The good news is that for generics, the full price is genuinely low: the complete, unsubsidised cost of a month of omeprazole is that €2.42 figure, not a co-pay on top of hidden insurance payments.
Spanish residents registered with the public system pay a percentage of the PVP rather than the full amount. The co-payment system was reformed in 2026 into income-based brackets — working-age residents pay roughly 40–60% depending on income, with new monthly caps for lower earners, and most pensioners pay 10% with monthly limits. None of this applies to a tourist with a private prescription, but it explains the two prices you might hear quoted for the same box.
What matters for a visitor:
- A foreign prescription generally won't be dispensed. Spanish pharmacies work from Spanish (or properly recognised EU cross-border) prescriptions. A US or UK prescription is, to a Spanish pharmacy, a well-intentioned piece of paper.
- A private Spanish prescription works everywhere. Any licensed Spanish doctor — in person or online — can issue a private e-prescription valid at all of Spain's roughly 22,000 pharmacies.
- Controlled medicines are the exception. Narcotics and psychotropics requiring Spain's special prescription — strong opioids, stimulants like ADHD medication, benzodiazepines in some cases — cannot be prescribed through a standard online e-prescription. No legitimate online service can promise those, and a doctor will always assess whether any prescription is clinically appropriate before issuing it.

Are generic medicines in Spain safe?
Yes. Generics sold in Spain are authorised by the Spanish Medicines Agency (AEMPS) or the European Medicines Agency under the same quality, safety and manufacturing standards as brand-name medicines. They must demonstrate bioequivalence to the original product before they can be sold, and they are inspected in the same way.
Can I ask for the brand-name version instead of the generic?
Usually, yes. On a private prescription you can ask the prescriber to name the brand. Within the public system, prescriptions are generally written by active ingredient and the pharmacy dispenses one of the lowest-priced versions, which may be a brand or a generic — at the same price either way.
Why does my medication have a different name in Spain?
Brand names are national; active ingredients are international. Spanish generics are simply named after the active ingredient plus the manufacturer — for example, Lipitor becomes atorvastatina cinfa or atorvastatina normon. Check the active ingredient on your box and a Spanish pharmacist or doctor can identify the equivalent immediately.
Do I need a prescription for generic antibiotics in Spain?
Yes. All antibiotics in Spain are prescription-only, whether generic or branded. Pharmacies face penalties for dispensing them without a valid Spanish prescription, and enforcement has tightened considerably since electronic prescriptions became standard. A quick online or in-person consultation with a Spanish doctor is the legitimate route.
What does EFG on a Spanish medicine box mean?
EFG stands for Equivalente Farmacéutico Genérico — a generic pharmaceutical equivalent. The initials appear on the packaging of every authorised generic in Spain. If the box says EFG, the medicine contains the same active ingredient, in the same dose and pharmaceutical form, as the original brand, with proven bioequivalence.
Is every medicine available as a generic in Spain?
No. Generics can only be sold once the original medicine's patent and data protection have expired, typically ten or more years after launch. Newer medicines have no generic version, which is why generics represent about 40% of packs dispensed in Spain rather than all of them.
