Published on: June 03, 2026

Searching for the cheapest sildenafil tablets uk online? At Cured Pharmacy, genuine UK-licensed sildenafil starts from just £0.45 per tablet, with transparent upfront pricing and a free clinical consultation completed in under three minutes. All treatments are dispensed by our UK-registered pharmacy team following assessment by a qualified prescriber.

How Sildenafil Works for Erectile Dysfunction

Sildenafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing the smooth muscle in blood vessels and increasing blood flow to the penis during sexual stimulation [1]. The medication does not cause an erection on its own — sexual arousal is still required for it to be effective.

Clinical trials have demonstrated that sildenafil significantly improves erectile function across a range of severities, with approximately 70-80% of men reporting improved erections when taking the medication as prescribed [1][2]. The active ingredient was originally developed for cardiovascular conditions before its efficacy for erectile dysfunction was discovered during clinical research in the 1990s.

Sildenafil typically begins working within 30-60 minutes of taking a tablet, with effects lasting up to four hours [2]. The medication is absorbed more slowly when taken with a high-fat meal, so for optimal results, it's best taken on an empty stomach or after a light meal. Your UK prescriber will determine the appropriate starting dose based on your medical history and any concurrent medications.

Sildenafil Dosage and How to Take It Safely

When you complete your free online consultation at Cured Pharmacy, our UK-registered prescribers review your medical history, current medications, and cardiovascular health to ensure sildenafil is safe and appropriate for you. The consultation takes under three minutes and covers all necessary safety checks required by MHRA guidelines.

If sildenafil is not suitable based on your assessment, our clinical team may recommend alternative treatments such as tadalafil, which has a longer duration of action, or discuss other management options for erectile dysfunction.

Standard Dosing Guidelines

The typical starting dose for sildenafil is 50mg, taken approximately one hour before sexual activity [2]. Depending on efficacy and tolerability, your prescriber may adjust this to 25mg or increase it to the maximum recommended dose of 100mg. Sildenafil should not be taken more than once in a 24-hour period.

Men taking certain medications — particularly nitrates for chest pain or alpha-blockers for prostate conditions — may not be suitable candidates for sildenafil due to the risk of dangerous blood pressure drops [3]. This is why a thorough clinical assessment by a UK prescriber is essential before starting treatment.

Why Choose Sildenafil Over Brand-Name Alternatives

Sildenafil is the generic version of Viagra, containing exactly the same active ingredient at the same strength and working in the identical way [1]. Since the original patent expired, multiple pharmaceutical manufacturers have been licensed to produce sildenafil, creating competition that has significantly reduced prices while maintaining the same clinical efficacy.

Generic medications in the UK must meet the same rigorous quality, safety, and efficacy standards set by the MHRA as branded versions [3]. At Cured Pharmacy, we only dispense UK-licensed sildenafil from reputable manufacturers, ensuring you receive genuine medication at a fraction of the cost of branded alternatives.

Choosing generic sildenafil offers substantial savings without compromising on quality or effectiveness. Many men find that the lower cost makes treatment more accessible for regular use, improving both their confidence and quality of life.

Treatment Active Ingredient Duration Starting Price
Sildenafil Sildenafil citrate 4-6 hours From £0.45
Sildenafil Eropid Sildenafil citrate 4-6 hours From £8.99
Tadalafil Tadalafil Up to 36 hours From £9.99
Tadalafil (Teva) Tadalafil Up to 36 hours From £9.99
Viagra Connect 50mg Sildenafil citrate 4-6 hours From £11.49
Cialis (Tadalafil) Tadalafil Up to 36 hours From £53.00

Common Side Effects and What to Expect

Visual disturbances such as a blue tinge to vision or increased light sensitivity can occur due to sildenafil's mild effect on PDE6 enzymes in the retina [2]. These effects are usually temporary and resolve as the medication is metabolised, but if they persist or worsen, contact your healthcare provider.

At Cured Pharmacy, our clinical team is available to answer questions about side effects and provide ongoing support throughout your treatment. If sildenafil causes persistent or bothersome side effects, we can discuss dose adjustments or alternative treatments that may be better suited to your needs.

Managing Side Effects

Most men tolerate sildenafil well, but like all medications, it can cause side effects in some individuals. The most commonly reported side effects include headache, facial flushing, indigestion, and nasal congestion [2]. These effects are typically mild to moderate and often diminish with continued use as your body adjusts to the medication.

Less common but more serious side effects include sudden vision or hearing loss, chest pain, or an erection lasting longer than four hours (priapism) [3]. If you experience any of these symptoms, seek immediate medical attention. Your prescriber will discuss all potential side effects during your consultation and provide guidance on when to seek medical help.

Sildenafil vs Tadalafil: Choosing the Right Treatment

Your choice between sildenafil and tadalafil should be guided by your lifestyle, frequency of sexual activity, and personal preference. During your consultation at Cured Pharmacy, our UK prescribers can help you understand which option may work best for your individual circumstances, taking into account any medical conditions or medications that might influence the decision.

Both medications are available at Cured Pharmacy with transparent pricing and the same rigorous clinical assessment process. If you start with one treatment and find it's not quite right, we can easily switch you to an alternative after discussing your experience with our clinical team.

Key Differences Between PDE5 Inhibitors

While both sildenafil and tadalafil are PDE5 inhibitors that treat erectile dysfunction through the same mechanism, they differ in their duration of action and dosing flexibility [4]. Sildenafil typically lasts for four to six hours, making it ideal for planned sexual activity, whereas tadalafil can remain effective for up to 36 hours, offering more spontaneity.

Some men prefer tadalafil's longer window of effectiveness, while others find sildenafil's shorter duration better suits their needs and lifestyle. Tadalafil is also available as a daily low-dose option for men who prefer continuous treatment rather than taking medication only when needed [4].
