How Sildenafil Works for Erectile Dysfunction

Sildenafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing blood vessels in the penis to improve blood flow 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 in approximately 70-80% of men with erectile dysfunction, regardless of the underlying cause [1][2]. The medication typically begins working within 30-60 minutes of administration and remains effective for up to four hours, though individual response times may vary.

Sildenafil was originally developed to treat cardiovascular conditions before its effects on erectile function were discovered during clinical trials. It received MHRA licensing in the UK in 1998 and has since become one of the most widely prescribed treatments for erectile dysfunction globally [2].

Sildenafil Dosage and How to Take It

Sildenafil is available in the UK in three strengths: 25mg, 50mg, and 100mg tablets. The standard starting dose recommended by NICE guidelines is 50mg, taken approximately one hour before sexual activity [3]. Your UK prescriber will determine the most appropriate dose based on your medical history, current medications, and response to treatment.

The medication should be swallowed whole with water and can be taken with or without food, though high-fat meals may delay its onset of action. You should not take more than one dose in a 24-hour period, and it's important to note that sildenafil only works when you are sexually aroused.

If the 50mg dose proves insufficient, your prescriber may increase it to 100mg or reduce it to 25mg if you experience side effects. Dose adjustments should always be made under medical supervision to ensure both safety and effectiveness.

When to Take Sildenafil for Best Results

For optimal results, take sildenafil on an empty stomach or after a light meal approximately 60 minutes before anticipated sexual activity. Clinical data suggests the medication reaches peak plasma concentrations within 30-120 minutes, with most men experiencing effects within the first hour [1]. Planning ahead allows the medication time to work effectively whilst maintaining spontaneity in your intimate life.

Sildenafil vs Viagra: Understanding the Difference

Sildenafil is the active pharmaceutical ingredient in Viagra, the original branded medication manufactured by Pfizer. When Pfizer's patent expired in 2013, other pharmaceutical companies gained approval to produce generic versions containing the same active ingredient at significantly lower prices.

Generic sildenafil and branded Viagra contain identical active ingredients in the same doses and are subject to the same rigorous MHRA quality standards. The primary differences are the manufacturer, appearance of the tablet, and price — generic sildenafil typically costs a fraction of the branded version whilst delivering equivalent clinical efficacy [2][3].

At Cured Pharmacy, we stock both generic sildenafil and branded options, allowing you to choose based on your preference and budget. All medications dispensed are UK-licensed and sourced from reputable manufacturers approved by the MHRA.

Why Choose Generic Sildenafil

Generic sildenafil offers the same therapeutic benefits as branded Viagra at a more accessible price point, making treatment affordable for long-term use. UK regulations ensure that generic medications meet identical standards for quality, safety, and efficacy as their branded counterparts, so you can be confident in your treatment choice regardless of which option you select.

Treatment Active Ingredient Duration of Action Starting Price
Sildenafil Sildenafil citrate 4-6 hours From £0.45
Tadalafil 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 Safety Considerations

Like all medications, sildenafil may cause side effects, though not everyone experiences them. The most commonly reported side effects include headache, facial flushing, indigestion, nasal congestion, and dizziness [1][4]. These effects are typically mild to moderate and tend to diminish with continued use as your body adjusts to the medication.

Serious side effects are rare but require immediate medical attention. These include sudden vision or hearing loss, chest pain, irregular heartbeat, or an erection lasting longer than four hours (priapism). If you experience any of these symptoms, seek emergency medical care immediately.

Sildenafil is not suitable for everyone. You should not take sildenafil if you are currently using nitrate medications for chest pain, as the combination can cause a dangerous drop in blood pressure [3][4]. Men with severe cardiovascular disease, recent stroke or heart attack, or certain eye conditions may also be advised against using sildenafil. Your UK prescriber will review your medical history during the online consultation to ensure the medication is safe and appropriate for you.

Drug Interactions to Be Aware Of

Sildenafil can interact with several other medications, including nitrates, alpha-blockers, some antifungal medications, certain antibiotics, and other PDE5 inhibitors. Always inform your prescriber of all medications and supplements you are currently taking, including over-the-counter products and herbal remedies, to avoid potentially harmful interactions.

Buy Sildenafil Online UK: The Cured Pharmacy Process

Purchasing sildenafil through Cured Pharmacy is straightforward, discreet, and fully compliant with UK regulations. The process begins with a free online consultation that takes under three minutes to complete. You'll answer questions about your medical history, current medications, and symptoms to help our UK-registered prescribers determine if sildenafil is suitable for you.

Once your consultation is reviewed and approved by a UK prescriber, your medication is dispensed by our GPhC-registered pharmacy (registration number 9012511) under the supervision of our superintendent pharmacist, Tarun Kumar (GPhC 2233073). We offer discreet packaging and fast delivery options, including next-day delivery across the UK.

Our transparent pricing means you'll see the exact cost before you complete your consultation — no hidden fees or surprise charges. At Cured Pharmacy, we guarantee the lowest prices in the UK, with sildenafil available from £0.45 per tablet, making effective treatment accessible and affordable.

Alternative Erectile Dysfunction Treatments Available

Whilst sildenafil is highly effective for many men, it's not the only treatment option available for erectile dysfunction. Tadalafil is another PDE5 inhibitor that works similarly to sildenafil but has a longer duration of action, remaining effective for up to 36 hours. This extended window can provide greater spontaneity and is available in both on-demand and daily low-dose formulations.

At Cured Pharmacy, we offer a comprehensive range of erectile dysfunction treatments to suit different lifestyles and preferences. Your UK prescriber can discuss which option may be most appropriate based on your individual circumstances, including how frequently you anticipate sexual activity, any side effects you've experienced with previous treatments, and your personal preferences.

All erectile dysfunction medications available through Cured Pharmacy are prescription-only and require clinical assessment by a UK-registered prescriber. This ensures you receive a treatment that is both safe and effective for your specific situation, with ongoing support from our clinical team.
