What's Sildenafil Tablets: Complete UK Guide to This Erectile Dysfunction Treatment

If you're asking what's sildenafil tablets, you're looking at one of the most prescribed medications for erectile dysfunction in the UK. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that helps men achieve and maintain erections by increasing blood flow to the penis during sexual stimulation. Available from £0.45 at Cured Pharmacy, sildenafil tablets offer a clinically proven, affordable solution for ED that has helped millions of men regain confidence in their intimate lives.

What's Sildenafil Tablets and How Do They Work?

Understanding what's sildenafil tablets starts with knowing the active pharmaceutical ingredient: sildenafil citrate. This compound works by inhibiting the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP) in the smooth muscle cells lining blood vessels in the penis[1]. When PDE5 is blocked, cGMP levels rise, causing blood vessels to relax and dilate, which increases blood flow to erectile tissue during sexual arousal.

It's crucial to understand that sildenafil tablets don't create spontaneous erections—sexual stimulation is still required for the medication to work. The drug typically begins working within 30 to 60 minutes of ingestion and remains effective for approximately four to six hours[2]. Clinical trials have demonstrated that sildenafil significantly improves erectile function across various severities of ED, with success rates ranging from 60% to 85% depending on underlying health conditions.

Sildenafil was originally developed to treat cardiovascular conditions but was found to be remarkably effective for erectile dysfunction during clinical trials. Since receiving MHRA approval, it has become the gold standard PDE5 inhibitor treatment, with generic versions now widely available at competitive prices across UK pharmacies.

What's Sildenafil Tablets Used For Beyond Erectile Dysfunction?

While most people asking what's sildenafil tablets are seeking treatment for erectile dysfunction, this medication has other licensed medical uses. Sildenafil is also prescribed under the brand name Revatio for pulmonary arterial hypertension (PAH), a condition where high blood pressure affects the arteries in the lungs and heart[3]. The same mechanism that improves penile blood flow also helps relax pulmonary blood vessels, reducing strain on the heart.

In the context of erectile dysfunction, sildenafil tablets are suitable for men experiencing difficulty achieving or maintaining erections sufficient for satisfactory sexual activity. This includes ED caused by psychological factors, physical conditions like diabetes or cardiovascular disease, or a combination of both. Our clinical team at Cured Pharmacy assesses each patient's medical history during the online consultation to ensure sildenafil is appropriate and safe for their individual circumstances.

Who Can Benefit from Sildenafil Tablets?

Men aged 18 and over experiencing erectile dysfunction may benefit from sildenafil tablets, subject to prescriber approval. The medication has proven effective across diverse patient populations, including those with underlying conditions such as type 2 diabetes, hypertension, and depression[4]. However, sildenafil is not suitable for everyone—men taking nitrates for chest pain, those with severe cardiovascular disease, or individuals with certain eye conditions require alternative treatments. Our UK-registered prescribers conduct thorough assessments to determine suitability before issuing any prescription.

What's Sildenafil Tablets Available Dosages and How to Take Them?

When exploring what's sildenafil tablets in terms of dosing options, you'll find three standard strengths available in the UK: 25mg, 50mg, and 100mg. The typical starting dose for most men is 50mg, taken approximately one hour before anticipated sexual activity[2]. Based on effectiveness and tolerability, your prescriber may adjust this to 25mg if side effects occur, or increase to 100mg if the response is insufficient.

Sildenafil tablets should be swallowed whole with water and can be taken with or without food, though high-fat meals may delay absorption and onset of action. The maximum recommended dosing frequency is once per 24-hour period. It's important never to exceed the prescribed dose, as higher amounts increase the risk of side effects without improving efficacy. At Cured Pharmacy, our clinical team provides clear dosing instructions tailored to each patient's needs during the prescription process.

Timing and Effectiveness Considerations

For optimal results with sildenafil tablets, timing matters. Taking the medication on an empty stomach typically produces faster results—often within 30 minutes—compared to after a heavy meal. The drug reaches peak plasma concentration approximately 60 minutes after ingestion, which is why most prescribers recommend taking it one hour before sexual activity. Effects can last up to six hours, giving you a reasonable window of opportunity without requiring precise timing of intimacy.

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
Viagra Connect 50mg Sildenafil citrate 4-6 hours from £11.49
Tadalafil Tadalafil Up to 36 hours from £9.99
Tadalafil (Teva) Tadalafil Up to 36 hours from £9.99
Avarante Tablets 10mg Tadalafil Up to 36 hours from £11.49
Cialis (Tadalafil) Tadalafil Up to 36 hours from £53.00

What's Sildenafil Tablets Potential Side Effects and Safety Profile?

Understanding what's sildenafil tablets involves knowing the potential side effects, though most men tolerate the medication well. The most commonly reported side effects include headache (affecting approximately 16% of users), facial flushing (10%), dyspepsia or indigestion (7%), and nasal congestion (4%)[1]. These effects are typically mild to moderate and often diminish with continued use as the body adjusts to the medication.

Less common but more serious side effects require immediate medical attention. These include sudden vision or hearing loss, priapism (an erection lasting longer than four hours), and severe allergic reactions. Visual disturbances may occur because PDE5 inhibitors can affect PDE6 enzymes in the retina, though this is rare with standard doses. Men with pre-existing cardiovascular conditions should be particularly vigilant about chest pain or irregular heartbeat while using sildenafil.

Drug interactions represent an important safety consideration. Sildenafil must never be combined with nitrates (used for angina) or riociguat (for pulmonary hypertension), as this combination can cause dangerous drops in blood pressure. Alpha-blockers, certain antifungals, HIV protease inhibitors, and some antibiotics may also interact with sildenafil, requiring dose adjustments or alternative treatments. Our online consultation at Cured Pharmacy specifically screens for these contraindications before any prescription is issued.

What's Sildenafil Tablets Cost and Where to Buy Safely in the UK?

When researching what's sildenafil tablets pricing, you'll find significant variation across UK pharmacies. At Cured Pharmacy, sildenafil is available from just £0.45 per tablet, with new customers receiving 20% off their first order using code Ednew—bringing the price down to £0.45 per tablet. This represents exceptional value compared to branded alternatives while maintaining the same active ingredient and therapeutic effect.

All sildenafil tablets sold in the UK must be obtained through a legitimate prescription from a registered healthcare professional. Cured Pharmacy operates as a fully GPhC-registered online pharmacy (registration number 9012511) under the supervision of superintendent pharmacist Tarun Kumar (GPhC 2233073). Our streamlined online consultation takes under three minutes and is reviewed by UK-registered prescribers who assess suitability before dispensing any medication.

Beware of unregulated websites offering sildenafil without prescription or at suspiciously low prices—these often supply counterfeit medications that may contain incorrect doses, contaminants, or no active ingredient at all. Purchasing from a registered UK pharmacy like Cured Pharmacy ensures you receive genuine, licensed medicines with proper quality controls, discreet packaging, and professional clinical oversight throughout the process.

Transparent Pricing and No Hidden Fees

At Cured Pharmacy, we believe in complete pricing transparency. The price you see before consultation is exactly what you pay—no hidden consultation fees, no surprise charges at checkout. Our competitive pricing on sildenafil tablets reflects our commitment to making essential treatments accessible to all men who need them, without compromising on quality, safety, or professional care.

What's Sildenafil Tablets Compared to Other ED Treatments?

For those wondering what's sildenafil tablets in relation to other erectile dysfunction medications, it's helpful to understand the PDE5 inhibitor class. Sildenafil, tadalafil, and vardenafil all work through the same basic mechanism but differ in onset time, duration of action, and side effect profiles. Sildenafil offers a balanced profile with relatively quick onset (30-60 minutes) and moderate duration (4-6 hours), making it suitable for planned sexual activity[2].

Tadalafil, by comparison, has a much longer half-life, remaining effective for up to 36 hours, which some men prefer for spontaneity. However, sildenafil's shorter duration can be advantageous for those who prefer the medication to clear their system more quickly or who experience side effects. The choice between treatments is highly individual and depends on lifestyle, preferences, and how your body responds to each medication.

Generic sildenafil offers identical efficacy to branded Viagra at a fraction of the cost. Both contain the same active ingredient in the same doses and must meet identical regulatory standards set by the MHRA. At Cured Pharmacy, we stock both generic sildenafil from £0.45 and branded options like Viagra Connect, allowing patients to choose based on their preferences and budget. Our clinical team can discuss the most suitable option during your online consultation.
