The Rise Of Unregulated Viagra

Erectile dysfunction (ED) is a common condition, affecting up to one in five (4.3 million) men in the UK, with treatments readily accessible through registered pharmacies and licensed online providers. [1]

Despite this, over the last twelve months, analysis of Amazon search data shows an estimated 120,000 searches for “Viagra” in the UK, alongside 65,000 searches for “sildenafil”, the active ingredient in Viagra. eBay search data also indicates an average monthly search volume of 34,000 for “sildenafil”. [2]

Top 10 statistics on how UK men access erectile dysfunction (ED) treatments

(MedExpress survey of 1,000 UK men, May 2026)

  1. 60% of UK men have purchased ED treatments from at least one source.
  2. Just 34% bought them in person from an official pharmacy.
  3. Only 22% used a regulated online pharmacy.
  4. 18% sourced ED treatments via Amazon or eBay, 17% through social media or online communities, 16% through friends, and 7% from overseas websites.
  5. Among men aged 18-24, 31% obtained ED treatments through friends and 20% via messaging apps or online communities.
  6. 27% say cost would lead them to purchase from unregulated sources.
  7. 24% cite embarrassment or fear of judgement as a factor.
  8. 23% say privacy concerns would drive them to unregulated sources.
  9. 19% want to avoid speaking to a doctor or pharmacist.
  10. Only 8% are unaware of the risks linked to unofficial ED medication.

Where are UK men getting their ED medication from?

In light of the evident interest in people purchasing prescription ED medications via online marketplaces and resale sites such as Amazon and eBay, medical experts at MedExpress have compiled the latest statistics on UK men’s attitudes towards erectile dysfunction treatments, including survey data on the scale of unregulated access to these treatments.

We uncovered where men are turning to access ED medication, the key motivations for purchasing from unofficial sources, and their perceived awareness of the potential risks involved

What medical experts say about buying ED medication without a prescription

Doctor Sophie Dix comments on access, cost and safety considerations around erectile dysfunction treatments:

“Branded ED treatments like Viagra can be more expensive and often come with the perception that they work better. However, that is not the case. Today, you can purchase unbranded prescriptions such as Sildenafil and Tadalafil which contain exactly the same active ingredients directly from regulated online pharmacies, which many men might be unaware of. This can help to mitigate the cost, is just as effective and is a much safer option than turning to cheaper and unregulated sources appearing online or through friends.”

“It’s important that medications for erectile dysfunction are supplied through a GP or registered pharmacy, following a medical assessment, to ensure the treatment is suitable, safe and not a symptom of a more serious health condition. Many people may also not be able to take these medications due to other prescriptions they are taking or pre-existing health conditions.”

“Treatments purchased through unregulated sources, including friends, resale sites and online communities, would bypass these checks and fail to meet public health safety standards and could be dangerous. Even if they appear identical to official treatments and you are eligible, there is also no reliable way to verify their safety, dosage, or whether they contain any active ingredient at all.”

“Purchasing from a regulated source is simply the only way to ensure the treatment is legitimate and safe to use.”

Methodology

In May 2026, MedExpress surveyed 1,000 UK men aged 18 and above to gauge their opinions, thoughts, and experiences of purchasing erectile dysfunction treatments.
