Standard sildenafil (25 mg, 50 mg, and 100 mg) is a prescription-only medicine in the UK. However, one form of sildenafil — Viagra Connect 50 mg — is available without a prescription from UK pharmacies, following a brief consultation with a pharmacist. This article explains what each route involves, who is eligible, and when a prescription is the more appropriate option.

Can you buy sildenafil over the counter?

Not in its standard prescription form. Sildenafil 25 mg, 50 mg, and 100 mg tablets are prescription-only medicines in the UK and cannot be purchased without a valid prescription from a registered prescriber.

The exception is Viagra Connect, a branded sildenafil 50 mg tablet reclassified by the MHRA in 2018 as a pharmacy medicine, meaning it can be dispensed without a prescription following a pharmacist consultation. It is the only form of sildenafil legally available without a prescription in the UK.

What is Viagra Connect and how does it differ from prescription sildenafil?

Viagra Connect is a branded 50 mg sildenafil tablet manufactured by Pfizer. It contains the same active ingredient as prescription sildenafil at the same dose and is pharmacologically identical. The difference is regulatory: Viagra Connect is accessed via a pharmacist consultation rather than a prescriber assessment, and it is only available at the 50 mg dose.

	Viagra Connect (OTC)	Prescription sildenafil
Dose available	50 mg only	25 mg, 50 mg, 100 mg
Prescription required	No	Yes
Assessment required	Pharmacist consultation	GP or prescriber assessment
Available on NHS	No	Yes, for eligible patients
Generic available	No	Yes
Typical cost	Higher per tablet	Lower (generic sildenafil)

For men who need a dose other than 50 mg, or who want access to lower-cost generic sildenafil, the prescription route is more appropriate.

See here for more guidance on how to differentiate between Sildenafil and Viagra.

What does the pharmacist consultation involve?

Before dispensing Viagra Connect, the pharmacist is required to conduct a brief clinical assessment. This typically covers:

Your age (Viagra Connect is for men aged 18 and over)
Whether you have been previously diagnosed with ED by a doctor
Your current medications, particularly nitrates and blood pressure medicines
Relevant medical history, including cardiovascular conditions, liver or kidney problems, and eye conditions
Whether you have had a recent stroke or heart attack

This is a genuine clinical step, not a formality. Men who are not suitable for sildenafil will not be dispensed Viagra Connect and will be directed to their GP instead.

Warning!

Viagra Connect is absolutely contraindicated for men taking nitrate medications in any form, including glyceryl trinitrate for chest pain and nitrate-containing recreational drugs such as amyl nitrite (poppers). The combination can cause a severe and potentially life-threatening drop in blood pressure. Always disclose all current medications during the consultation.

Who is eligible to buy Viagra Connect OTC?

Viagra Connect is suitable for men who:

Are aged 18 or over
Have been previously diagnosed with ED by a doctor
Are not taking nitrate medications or other contraindicated medicines
Do not have a history of severe cardiovascular disease, recent stroke or heart attack, or low blood pressure
Do not have severe liver or kidney impairment

Men who have not previously been assessed for ED, who have complex health histories, or who require a different dose should see their GP or use a regulated online prescribing service for a more comprehensive assessment.

What does "non-prescription sildenafil" mean in a UK context?

The term "non-prescription sildenafil" in the UK refers specifically to Viagra Connect 50 mg. It does not refer to generic sildenafil, which remains prescription-only at all doses. It also does not refer to unlicensed products sold online without a prescription, which are neither legal nor safe.

Good to know

Some websites use the phrase "no prescription needed" to describe sildenafil products sold without a medical assessment. This is not a legitimate route. Prescription-only sildenafil cannot legally be sold without a valid UK prescription, and products offered this way are likely to be counterfeit or unlicensed.

Where can you buy sildenafil over the counter?

Viagra Connect is available from most major UK pharmacy chains including Boots, Superdrug, Lloyds Pharmacy, and independent community pharmacies. It is also available from GPhC-registered online pharmacies that offer a pharmacist consultation service.

To verify that any online pharmacy selling Viagra Connect is legitimate, check for the GPhC internet pharmacy logo on their website and click it. It should link directly to the pharmacy's entry in the GPhC register at pharmacyregulation.org. If it does not, do not purchase from that site.

Can you get sildenafil on prescription online?

Yes. Regulated online prescribing services staffed by UK-registered prescribers offer a legal and clinically appropriate route to prescription sildenafil at all doses. The process involves completing an online health questionnaire, a review by a registered prescriber, and dispensing and delivery from a GPhC-registered pharmacy if the assessment is passed.

This route provides access to generic sildenafil at 25 mg, 50 mg, and 100 mg, typically at lower prices than Viagra Connect, with the added benefit of a comprehensive clinical assessment. DoktorABC connects UK patients with licensed prescribers who can assess suitability and issue private prescriptions where clinically appropriate.

Good to know

Online prescribing services must be registered with the Care Quality Commission (CQC) as clinical services and use GPhC-registered pharmacies. Checking both registrations is an important safety step before using any online service.

What are the risks of buying sildenafil without medical clearance?

Some websites offer to sell sildenafil or "Viagra" without any prescription or medical assessment. This is illegal under UK medicines regulations and carries genuine health risks.

The MHRA has consistently warned that a significant proportion of ED medicines purchased from unregulated online sources are counterfeit, contain no active ingredient, incorrect doses, or harmful contaminants.

Beyond counterfeit risk, taking sildenafil without a medical assessment means potential drug interactions and contraindications go undetected. Sildenafil can interact dangerously with nitrates, certain antifungals, HIV medications, and some blood pressure medicines. Without a clinical review, these risks cannot be appropriately managed.

Warning!

If a website offers sildenafil without requiring a prescription or medical questionnaire, at prices far below the market range, or without a verifiable GPhC logo, do not purchase from it. Report suspected counterfeit products to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

When is a prescription the better option?

For many men, the prescription route offers meaningful advantages over Viagra Connect:

Dose flexibility: Prescription sildenafil is available at 25 mg, 50 mg and 100 mg. Men who need a lower dose for tolerability or a higher dose for efficacy must use the prescription route. See our sildenafil dose guide for a full breakdown of available doses and starting guidance.
Cost: Generic sildenafil on prescription is significantly cheaper than Viagra Connect per tablet. See our sildenafil price guide for a full cost comparison across doses and providers
Comprehensive assessment: A prescriber assessment is more thorough than a pharmacist consultation and includes a review of underlying causes of ED, which can sometimes indicate cardiovascular or hormonal conditions requiring treatment.
NHS access: Eligible patients can access sildenafil on the NHS for the standard prescription charge. This is not available via the OTC route.

Final thoughts

Viagra Connect has made sildenafil more accessible for many men in the UK since 2018, and the pharmacist consultation provides an appropriate level of clinical screening for straightforward cases. For men who need dose flexibility, want the lower cost of generic sildenafil, or have a more complex health history, the prescription route offers a more comprehensive and cost-effective option. Whichever route you choose, the most important principle is the same: access your treatment from a legitimate, regulated source.
