Generic Viagra contains sildenafil, the same active ingredient as Viagra. In Spain it is prescribed for erectile dysfunction in adult men, as 25, 50 and 100 mg tablets.
Below the price table you can see which dose people start on, how food changes the timing, who should avoid it and how prescriptions work here if you have moved from the UK or elsewhere. In Spain, prescription-only medicines may not be sold online, and customs can hold a parcel that contains them. We do not check prescriptions: talk to your doctor before you order.
Before you order. Never take sildenafil with nitrates (GTN, isosorbide) or poppers: your blood pressure can drop dangerously. The usual starting dose is 50 mg; 100 mg is the maximum, not the norm. In Spain, prescription-only medicines may not be sold online, and customs can hold a parcel that contains them. We do not check prescriptions: talk to your doctor before you order.

No Viagra Connect in Spain
If you’ve lived in the UK, you may know Viagra Connect: 50 mg sildenafil that pharmacists there have been allowed to sell without a prescription since 2018. Spain has nothing like it. Every sildenafil product in CIMA, the Spanish medicines database, is prescription-only, and a Spanish pharmacist can’t hand it over because you show a UK box or a UK prescription.
Prescriptions from another EU country are a different matter: Spanish pharmacies can dispense them, provided they include the details the law requires (more on this below).
Brand or generic: what you actually get
Viagra was the first tablet for erection problems and has been authorised in Spain since 1998. Generics arrived when the patent ran out in 2013. A Spanish generic carries the letters EFG (equivalente farmacéutico genérico): same active ingredient, same strength, and the Spanish Medicines Agency (AEMPS) only approves it once it’s shown that your body absorbs it just like the original. What changes is the name, the colour of the tablet, some inactive ingredients and the price.
One thing that confuses people: sildenafil 20 mg (Revatio and its generics) is for pulmonary hypertension, a lung and heart condition. It isn’t prescribed for erections.
The product on this page doesn’t name its manufacturer and isn’t supplied by a Spanish pharmacy. If you want to know what you’ll receive, ask us for the manufacturer and batch number before ordering.
25, 50 or 100 mg?
The Spanish product information (ficha técnica) starts at 50 mg. Depending on how well it works and how you tolerate it, your doctor may raise it to 100 mg or lower it to 25 mg.
| Tablet | When the product information uses it |
|---|---|
| 25 mg | Starting dose with severe kidney disease or liver problems, alongside an alpha-blocker (doxazosin, tamsulosin…), or with medicines that slow its breakdown, such as erythromycin or ketoconazole. |
| 50 mg | The usual starting dose. |
| 100 mg | The maximum, if 50 mg isn’t enough and side effects aren’t a problem. |
Age on its own isn’t a reason to lower the dose. Anything above 100 mg isn’t authorised and simply means more side effects. Bigger packs work out cheaper per tablet, but 360 tablets is a lot to buy before you know the medicine suits you: let your doctor settle the dose first.
Timing, food and how long it lasts
On an empty stomach, sildenafil reaches its highest blood level 30 to 120 minutes after you take it, an hour on average. In one study of men who hadn’t eaten, an erection firm enough for sex took a median of 25 minutes to appear. That’s why the advice is to take it about an hour beforehand.
Food slows it down: after a meal it takes about an hour longer to peak, and the peak is 29% lower. Men in studies could still get an erection 4–5 hours after a dose, while blood levels halve every 3–5 hours. It doesn’t give you an erection that lasts for hours: you get one when you’re aroused, and it goes down afterwards.
When should I take it?
Tell us what you’ve eaten and how long it is until you plan to have sex. This is an illustration based on the product information, not personal dosing advice.
Food
Time until sex: 1 h
Who shouldn’t take it
According to the Spanish product information, don’t take sildenafil if you:
- use any nitrate (GTN tablets, spray or patches; isosorbide mononitrate or dinitrate), poppers (amyl nitrite) or riociguat;
- have a heart condition that makes sex unsafe, such as unstable angina or severe heart failure;
- have recently had a heart attack or stroke;
- have blood pressure below 90/50, severe liver disease, or retinitis pigmentosa or another inherited retinal disease;
- have lost the sight of one eye because of NAION (non-arteritic anterior ischaemic optic neuropathy);
- are allergic to sildenafil or any of the other ingredients.
Check with a doctor first if you have a curved penis (Peyronie’s disease), sickle cell anaemia, myeloma or leukaemia, an active stomach ulcer or a bleeding disorder.
Side effects
Headache is the most common, affecting more than 1 man in 10. Flushing, a blocked nose, dizziness, nausea, indigestion and changes in vision (blurring, or a blue or green tinge to colours) are also common. They’re usually mild and wear off within a few hours.
Call 112 or go to A&E (urgencias) if:
- you have chest pain or tightness, feel short of breath or about to faint; tell them you’ve taken sildenafil and when, because it changes how they can treat you;
- an erection lasts more than 4 hours;
- you suddenly lose sight in one or both eyes, or your hearing drops;
- your face, tongue or throat swells.
If you’ve taken too much, call Spain’s poisons information service (Servicio de Información Toxicológica) on 91 562 04 20.
You can report side effects to the Spanish pharmacovigilance system at notificaRAM.es.
Interactions
| Medicine | What happens |
|---|---|
| Nitrates, poppers, riociguat | Severe drop in blood pressure. Must not be combined. |
| Ritonavir | Eleven times as much sildenafil in the blood. Not recommended together. |
| Erythromycin, ketoconazole, itraconazole, saquinavir | Higher sildenafil levels (almost three times as much with erythromycin). Start at 25 mg. |
| Doxazosin and other alpha-blockers | Dizziness or fainting when you stand up. Only once the alpha-blocker dose is stable, starting at 25 mg. |
| Grapefruit juice | A modest rise in sildenafil levels. |
What it costs
In a Spanish farmacia you pay the full price for sildenafil: it isn’t funded for erectile dysfunction (BIFIMED, Spanish Ministry of Health). The price depends on the brand, the strength and the pack size, and EFG generics are usually cheaper than Viagra. With a prescription, the pharmacist can tell you what’s in stock.
This shop’s prices are in the table above: three strengths, packs of 10 to 360, some with extra tablets. Before you compare, remember that the manufacturer isn’t stated, that a large pack only makes sense once your doctor has confirmed your dose, and that if customs hold the parcel, the saving is gone.
Other options
- Generic Cialis (tadalafil) works for up to 36 hours and food doesn’t delay it. There’s also a 5 mg daily regimen.
- Generic Levitra (vardenafil) gives a similar window to sildenafil; a very fatty meal slows it too.
Our range also includes Viagra Professional, Viagra Soft and Kamagra. These are Indian-made sildenafil products that aren’t authorised in Spain. If what you want is something you don’t have to swallow with water, Spanish pharmacies stock authorised chewable and orodispersible sildenafil.
Getting a prescription as a foreign resident
If you’re registered with the Spanish health system and have a tarjeta sanitaria (health card), book an appointment with your médico de familia, the GP at your local centro de salud. A private GP can prescribe it as well, which is often quicker. Expect a blood pressure check and questions about your heart and current medicines, and perhaps a blood test: erection problems are sometimes the first sign of diabetes or furred-up arteries.
A prescription issued in another EU country can be dispensed in Spain under Royal Decree 81/2014, as long as it includes the patient’s and doctor’s details and the medicine’s name, strength and dose. UK prescriptions aren’t covered by that system.
Delivery
We don’t have a shop, pharmacy or pick-up point anywhere in Spain: orders are sent by post or courier. Times and terms are on our delivery conditions page.
Questions people ask
Can I buy Viagra over the counter in Spain?
No. Unlike Viagra Connect in the UK, every sildenafil product in Spain needs a prescription, and even licensed Spanish online pharmacies can’t sell it.
Is generic sildenafil as good as Viagra?
Yes, if it’s an authorised EFG generic: same active ingredient, same dose, and absorption checked by the AEMPS. The tablet may look different; if one brand doesn’t agree with you, mention it to the pharmacist.
Should I take 50 mg or 100 mg?
You start with 50 mg. If that’s not enough and you tolerate it well, your doctor can move you to 100 mg; if side effects bother you, to 25 mg. Never two tablets in one day.
How long does sildenafil last?
You have a window of roughly 4–5 hours in which you can get an erection when aroused. It isn’t a constant erection.
Will my UK prescription work in a Spanish pharmacy?
Not as a rule: Spain accepts prescriptions from EU countries, and the UK is no longer one. You’ll need to see a GP in Spain, either at the centro de salud or privately.
Can I drink alcohol with it?
In studies, a moderate amount of alcohol didn’t make the drop in blood pressure worse. But alcohol makes erections harder to get and adds to dizziness, so keep it light.
Does the Spanish health system pay for it?
No. Even with a prescription from your médico de familia, you pay the full price at the pharmacy.
