Erectile dysfunction, or ED, sometimes still called impotence, is treated in the UK through a range of options: tablets, non-drug devices, injectable or topical treatments, hormone treatment where a hormonal cause is found, psychological support, and, rarely, surgery. There is no single "best" treatment. The right option depends on what is causing the difficulty, which is why a proper assessment comes before any prescription rather than after.

This page sets out every recognised treatment route available in the UK, how each one works, what the evidence says about how well they work, and how to get genuine treatment safely.

What Is Erectile Dysfunction, and Is "Impotence" the Same Thing?

Yes. Erectile dysfunction is the persistent or recurrent difficulty getting or maintaining an erection firm enough for sexual intercourse or other satisfactory sexual activity, and 'impotence' is an older term that has commonly been used for erectile dysfunction. Erectile dysfunction symptoms are not limited to a one-off episode.

"Impotence" vs "Erectile Dysfunction": Is There a Difference?

In modern use, 'impotence' is generally used to mean erectile dysfunction, although the older term was sometimes used more broadly. Sometimes to describe infertility as well as erection difficulty, which is one reason "erectile dysfunction" replaced it in clinical use: it is more precise and less open to confusion.

How Common Is It in the UK?

ED is common, particularly as men get older, but it can affect men of any age. The likelihood of experiencing erection problems generally increases with age, although ED is not an inevitable part of getting older.

How Is ED Treated in the UK? An Overview of the Options

There are seven broad routes to treating erectile dysfunction in the UK, and most men are suitable for more than one.

Here, tablets are described as oral medicines and are also classed as oral medications.

These medical treatments are only part of the wider picture, because some men also benefit from lifestyle changes or psychological support.

Tablets: PDE5 Inhibitors

PDE5 inhibitor tablets are the most familiar ED treatment and work by supporting the body's own arousal response rather than creating it artificially.

How They Work

During sexual arousal, natural signals cause the blood vessels in the penis to relax. PDE5 inhibitors help prolong this effect, making it easier to achieve and maintain an erection. Sexual stimulation is still required. Sildenafil, vardenafil and avanafil generally have a shorter duration of action than tadalafil, which can remain effective for up to 36 hours. The medicines differ in how quickly they work, how long their effect can last and how they are taken.

What They Can Not Do

PDE5 inhibitors do not increase relationship desire or create arousal on their own. They still require stimulation to work, and while they can help manage erection problems, they do not treat whatever is causing the ED in the first place, which is why they are often described as managing the symptom rather than the underlying cause.

Non-Drug Options: Vacuum Erection Devices

A vacuum erection device is a non-drug option that can be effective for many men and is one of the less familiar treatments available.

How They Work

The device creates a vacuum around the penis, drawing blood in, and a constriction ring is then placed at the base to hold that blood in place once the device is removed. A suitable device should include a vacuum limiter to reduce the risk of injury from excessive pressure.

Why They Are Worth Knowing About

On the evidence NICE has reviewed, vacuum devices can achieve response rates of up to 90%, higher than typical figures for PDE5 inhibitor tablets. They are commonly used where tablets are contraindicated or have not worked. Because it does not involve medication, it does not have the drug interactions associated with PDE5 inhibitors.

Second-Line Options: Alprostadil

Alprostadil is a treatment used when tablets have not worked or are not suitable, and it works through a completely different mechanism.

Injection, Urethral Pellet and Cream

Alprostadil is chemically identical to a naturally occurring compound called prostaglandin E1, and it acts directly on the erectile tissue rather than relying on the arousal signal that tablets depend on. It is available as a self-administered injection directly into the penis, as a small pellet inserted into the urethra, or as a topical cream, a newer route for the same medicine.

When These Are Used

These are second-line options, generally considered after tablets have not been effective or are not appropriate, and the first use is typically supervised by a clinician. Alprostadil can cause a prolonged erection, so it should not be combined with other ED treatments unless specifically advised by a specialist.

Treating the Underlying Cause

Sometimes the most effective ED treatment is addressing underlying conditions that may be causing it, rather than treating the erection difficulty in isolation.

Hormone Treatment

Where clinically significant low testosterone or another hormonal deficiency is confirmed through appropriate assessment and testing, hormone replacement therapy may be appropriate, prescribed and monitored by a suitably qualified clinician. It is not a default or general-purpose ED treatment, and it is only considered once a genuine deficiency has been identified.

Managing Diabetes, Blood Pressure and Cholesterol

Conditions that affect blood flow, such as diabetes, high blood pressure, high cholesterol, and cardiovascular disease, are among the most common physical causes of ED, so improving control of these conditions and assessing cardiovascular health can improve erectile function alongside, or sometimes instead of, a dedicated ED treatment. Lifestyle changes can also help: regular exercise can significantly improve erectile function, losing weight and maintaining a slimmer waistline are linked to better erectile function, quitting smoking can enhance erectile function, and a diet high in fruits and vegetables may improve ED.

Psychological Therapy

Where psychological causes or other psychological conditions are the main driver, structured psychological support addresses the actual cause rather than working around it, and can be used alongside or instead of a physical treatment.

Relationship counselling may help address relationship difficulties or anxiety that are contributing to ED.

ED can also create a cycle of anxiety that structured support such as ED therapy or cognitive behavioural therapy can help break.

Low-Intensity Shockwave Therapy: Where the Evidence Stands

Low-intensity shockwave therapy is an emerging treatment, available privately in the UK, and it is not yet a first-line option because the evidence base is still developing.

A 2025 systematic review covering 21 trials and 1,357 men with mild to moderate ED found some evidence of benefit, but the certainty of that evidence was limited by small studies, non-standard protocols and short follow-up periods. It is also worth knowing that focused and radial pressure-wave devices are different technologies, and evidence for one does not automatically apply to the other.

A device carrying appropriate UKCA or CE marking indicates that it meets applicable regulatory requirements, but this does not by itself establish that the device is effective for ED.

What Does ED Treatment Cost in the UK?

Cost varies significantly by treatment type, and it is confirmed as part of a consultation rather than fixed in advance, since the appropriate option, dose and quantity depend on your individual assessment.

As a general shape, tablets are often among the lower-cost ongoing options, non-drug devices involve a one-off cost rather than a recurring one, and second-line treatments such as alprostadil tend to cost more per use.

None of this should be the deciding factor in which treatment is right for you, suitability comes from the assessment, and cost is a separate, practical conversation to have once you know which options actually apply to you.

Getting Genuine Treatment Safely in the UK

Buying ED treatment from an unregistered source carries a real, well-documented risk of counterfeit or contaminated medicine, which is why where you get treatment matters as much as which treatment you choose.

Why This Matters

Between 2021 and 2025, an estimated 19.5 million doses of illegal ED medicines were seized in the UK, described by the MHRA as the equivalent of two double-decker buses' worth of tablets. Testing found products with no active ingredient, the wrong dose, or toxic contaminants. Two ED medicines, sildenafil (as Viagra Connect) and tadalafil (as Cialis Together), are also available as pharmacy medicines following a pharmacist consultation, without needing a full prescription, which is a legitimate route worth knowing about alongside prescription options.

How To Check a Pharmacy Is Registered

A genuine UK online pharmacy is listed on the General Pharmaceutical Council register under a named superintendent pharmacist, has a real trading address, and will always carry out a proper assessment before supplying a prescription-only medicine. Warning signs include no clinical assessment being required, pressure to buy quickly, claims that a prescription is unnecessary where one is required, or payment methods that offer little consumer protection.

What Happens at an Assessment

An ED assessment looks at the whole picture, including your medical history and relationship history, because the right treatment depends on the cause.

Expect questions about how long the difficulty has been happening, your symptoms, whether they occur in every situation or only some, including whether they occur with a sexual partner, alongside your general health and lifestyle, any medicines you are taking, and cardiovascular risk factors such as blood pressure, cholesterol and smoking.

Persistent problems can point to an underlying physical cause, while situation-specific patterns may suggest psychogenic ED or other psychological causes.

A prescriber may suggest blood tests or a physical examination depending on what comes up, assess underlying health conditions, and review whether certain medications or certain medicines could cause erectile dysfunction, then discuss which treatment options are suitable for you specifically rather than defaulting to one.
