Tadalafil for Premature Ejaculation: What the Evidence Shows

Published: 15 October 2026

Tadalafil for premature ejaculation is not currently licensed in the UK for this condition, though some research has explored its potential role. Tadalafil (generic Cialis) is a PDE5 inhibitor licensed to treat erectile dysfunction (ED), and while some men with both ED and premature ejaculation (PE) may notice modest improvements in control when using it, the evidence is limited and it is not a first-line treatment for PE alone [4]. This page explains what tadalafil does, which treatments are licensed for premature ejaculation in the UK, and how to access safe, effective care through a pharmacist-led consultation.

What Is Tadalafil and How Does It Work?

Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor licensed in the UK for the treatment of erectile dysfunction [4]. It works by relaxing blood vessels in the penis, which helps improve blood flow and makes it easier to achieve and maintain an erection when sexually aroused. Tadalafil is available in on-demand doses (10 mg or 20 mg taken at least 30 minutes before sex, with effects lasting up to 36 hours) and daily doses (2.5 mg or 5 mg) for men who prefer regular treatment [4].

Unlike medicines specifically designed for premature ejaculation, tadalafil does not directly affect the ejaculatory reflex or delay orgasm. Its primary action is on erectile function, not ejaculatory control. However, some men with both ED and PE report feeling less anxious and more in control during sex when their erections are more reliable, which may indirectly influence timing [2]. It is important to understand that tadalafil is not licensed or recommended as a treatment for premature ejaculation on its own.

If you are considering tadalafil for any reason, it must be prescribed after a consultation with a UK-registered prescriber who will review your medical history, current medicines, and suitability. At Cured Pharmacy, our pharmacist-led online consultation ensures safe, personalised care.

Does Tadalafil Help Premature Ejaculation?

The evidence for using tadalafil for premature ejaculation is limited and mixed. Some small studies have suggested that daily tadalafil may modestly improve ejaculatory control in men who have both ED and PE, possibly by reducing performance anxiety and improving overall sexual confidence. However, these studies are not large or robust enough to support tadalafil as a licensed treatment for PE, and it is not approved by UK regulators for this indication [4].

Premature ejaculation is a distinct condition from erectile dysfunction, though the two can occur together. PE is usually defined as ejaculation that happens sooner than desired, often within one minute of penetration, and causes distress or frustration. The main licensed treatments for PE in the UK are selective serotonin reuptake inhibitors (SSRIs) such as dapoxetine (a short-acting SSRI taken on demand) or off-label use of other SSRIs, as well as topical anaesthetic sprays or creams that reduce sensitivity [2].

If you are experiencing premature ejaculation, it is important to discuss your symptoms with a healthcare professional who can recommend the most appropriate treatment. Using tadalafil without a clear diagnosis or prescription is not advised, and it may not address the underlying cause of PE. A pharmacist or GP can help identify whether you have PE, ED, or both, and guide you to the right treatment.

When Might Tadalafil Be Considered?

Tadalafil may be considered if you have both erectile dysfunction and premature ejaculation, as treating the ED component can sometimes improve overall sexual function and confidence. In this scenario, a prescriber might recommend tadalafil alongside behavioural techniques or other PE treatments. However, tadalafil alone is unlikely to resolve PE if ED is not also present, and it should never be used as a substitute for evidence-based PE therapies [2][4].

Licensed Treatments for Premature Ejaculation in the UK

The most commonly recommended treatments for premature ejaculation in the UK include behavioural techniques, topical anaesthetics, and certain medicines. Behavioural approaches such as the 'stop-start' or 'squeeze' techniques can help improve control over time and are often recommended as a first step, sometimes alongside counselling or sex therapy [2].

Topical anaesthetic sprays or creams containing lidocaine or prilocaine can reduce sensitivity and delay ejaculation. These are applied to the penis a short time before sex and washed off before penetration. Dapoxetine, a short-acting SSRI, is the only oral medicine licensed specifically for PE in the UK. It is taken one to three hours before sex and works by increasing serotonin levels, which can delay ejaculation [2].

Other SSRIs, such as sertraline or paroxetine, are sometimes used off-label for PE when taken daily. These are not licensed for this indication but may be prescribed by a GP or specialist after discussion. If you are unsure which treatment is right for you, a consultation with a healthcare professional is essential. At Cured Pharmacy, our pharmacist-led service can help identify whether ED treatment, PE treatment, or both may be appropriate, and refer you to your GP if needed.

Tadalafil for Premature Ejaculation: What to Know Before Using It

If you are considering tadalafil for premature ejaculation, it is important to have realistic expectations. Tadalafil is not a cure for PE and is not licensed for this use. While some men with both ED and PE may experience indirect benefits, such as reduced anxiety and improved sexual confidence, tadalafil does not directly delay ejaculation or address the physiological mechanisms of PE [4].

Before using tadalafil, you must complete a consultation with a UK-registered prescriber who will assess your medical history, current medicines, and any conditions that might make tadalafil unsuitable. Tadalafil must never be taken with nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, or recreational drugs known as 'poppers', as this combination can cause a dangerous drop in blood pressure [4]. Men taking alpha-blockers for prostate symptoms or blood pressure should also be assessed carefully, as there is a risk of dizziness or low blood pressure.

Common side effects of tadalafil include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. These are usually mild and temporary. Serious side effects are rare but include priapism (an erection lasting more than four hours), sudden vision or hearing loss, and chest pain during sex. If any of these occur, seek urgent medical help [4]. Always read the patient information leaflet and follow your prescriber's advice.

Who Should Not Use Tadalafil?

Tadalafil is not suitable for everyone. It should not be used if you take nitrates, nicorandil, riociguat, or another PDE5 inhibitor, or if you have severe heart or liver problems, very low blood pressure, or a history of stroke or heart attack in the past six months. Men with a history of non-arteritic anterior ischaemic optic neuropathy (NAION), a rare cause of sudden vision loss, should also avoid tadalafil [4]. Your prescriber will check your full medical history during the consultation.

How to Access Tadalafil and PE Treatment at Cured Pharmacy

At Cured Pharmacy, we offer a straightforward, confidential online consultation for erectile dysfunction treatment. If you are experiencing both ED and premature ejaculation, our pharmacist-led service can help you understand your options and, where appropriate, arrange a prescription for tadalafil or another PDE5 inhibitor. All consultations are reviewed by a UK-registered prescriber, and medicines are dispensed by our GPhC-registered pharmacy (GPhC 9012511).

If your main concern is premature ejaculation without ED, we recommend discussing this with your GP, as PE-specific treatments such as dapoxetine or topical anaesthetics may be more suitable. Our team can provide guidance and signpost you to the right care. Tadalafil is available in several formulations at Cured Pharmacy, including generic tadalafil from £7.95 (or £6.36 for first orders with code Ednew), branded Cialis from £12.00 (£9.60 with code Ednew), and Teva tadalafil 20 mg from £9.99 (£7.99 with code Ednew).

To start your consultation, simply complete our online questionnaire. Your answers are reviewed by a prescriber, and if treatment is appropriate, your medicine is dispensed and posted discreetly to your address. If tadalafil is not suitable, or if your symptoms suggest a condition that needs further investigation, we will let you know and recommend seeing your GP. We are here to support you with safe, evidence-based care.

When to See Your GP About Premature Ejaculation or ED

If you are experiencing premature ejaculation, erectile dysfunction, or both for the first time, it is important to see your GP. ED can be an early warning sign of underlying health conditions such as heart disease, high blood pressure, or diabetes, and addressing these can improve both your general health and sexual function [1][2]. Similarly, PE can sometimes be linked to psychological factors, relationship issues, or other health concerns that benefit from professional assessment.

Your GP can take a full history, perform any necessary tests, and discuss the most appropriate treatments. They may refer you to a specialist if needed, or prescribe treatments such as dapoxetine for PE or a PDE5 inhibitor for ED. Do not be embarrassed to raise these issues—sexual health is an important part of overall wellbeing, and GPs are experienced in discussing these concerns in a supportive, non-judgemental way [1].

If you have already been assessed and are looking for convenient, ongoing access to ED treatment, Cured Pharmacy's online consultation service offers a safe and discreet alternative. However, if your symptoms change, worsen, or do not improve with treatment, always return to your GP for further advice. Premature ejaculation and erectile dysfunction are common and treatable, and seeking help is the first step towards regaining confidence and enjoying a fulfilling sex life.

Red Flags That Need Urgent Attention

Seek urgent medical help if you experience an erection lasting more than four hours (priapism), sudden loss of vision or hearing, or chest pain during sexual activity. These are rare but serious side effects that require immediate attention [4]. If you have chest pain, do not take any more tadalafil or other ED medicine, and call 999 or go to A&E. Do not take nitrates (such as GTN spray) if you have used tadalafil in the past 48 hours, as this can cause a dangerous drop in blood pressure.
