How Sildenafil Tablets Work 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 active ingredient blocks the PDE5 enzyme that normally breaks down cyclic guanosine monophosphate (cGMP), allowing smooth muscle relaxation and increased penile blood flow when aroused.

Clinical trials demonstrate that sildenafil improves erectile function in approximately 70-80% of men with erectile dysfunction, regardless of underlying cause [1][2]. The medication typically begins working within 30-60 minutes of oral administration and remains effective for up to 4-6 hours, though individual response times vary based on factors like food intake and metabolism.

It's important to understand that sildenafil requires sexual stimulation to work — it doesn't cause automatic erections. The medication enhances your body's natural response to arousal rather than artificially triggering erections, which is why many men find it produces more natural-feeling results compared to other treatment options.

Sildenafil vs Viagra: Understanding Generic and Branded Options

Sildenafil is the generic form of Viagra, containing exactly the same active ingredient at identical doses. When Pfizer's patent on Viagra expired in 2013, multiple pharmaceutical manufacturers received MHRA approval to produce generic sildenafil tablets in the UK, making the treatment significantly more accessible and affordable [3].

The clinical efficacy and safety profile of generic sildenafil matches branded Viagra precisely because both must meet the same stringent MHRA licensing standards. Generic manufacturers must demonstrate bioequivalence — meaning the medication is absorbed into your bloodstream at the same rate and extent as the original branded product.

At Cured Pharmacy, we stock both generic sildenafil and branded options like Viagra Connect. Generic sildenafil offers exceptional value, whilst some patients prefer branded products for personal reasons. Your UK prescriber can discuss which option best suits your clinical needs and budget during your free consultation.

Why Choose Generic Sildenafil?

Generic sildenafil provides the same therapeutic benefits as Viagra at a fraction of the cost, with prices starting from £0.45 per tablet at Cured Pharmacy. This makes ongoing treatment more sustainable for men who need regular medication, particularly those taking sildenafil several times per month. All generic sildenafil we dispense is manufactured by UK-licensed pharmaceutical companies and subject to the same quality controls as branded alternatives.

Sildenafil Dosage: Finding the Right Strength

Sildenafil tablets are available in three main strengths in the UK: 25mg, 50mg, and 100mg. The recommended starting dose for most men is 50mg, taken approximately one hour before sexual activity [4]. Your prescriber may adjust this based on your response to treatment and any side effects you experience.

If the 50mg dose proves effective but causes mild side effects, your prescriber might reduce you to 25mg. Conversely, if 50mg provides insufficient response and you tolerate it well, the dose may be increased to 100mg — the maximum recommended single dose [4]. Never exceed one dose in a 24-hour period regardless of strength.

Factors influencing your optimal dose include age, other medications you're taking, underlying health conditions, and severity of erectile dysfunction. Some men find lower doses perfectly adequate, whilst others require the maximum strength. This is why clinical assessment by a UK prescriber is essential before starting treatment.

Timing and Food Interactions

For best results, take sildenafil on an empty stomach or after a light meal. High-fat meals can delay absorption and reduce effectiveness, potentially extending the time before the medication works [4]. Avoid grapefruit juice, which can increase sildenafil levels in your bloodstream and raise the risk of side effects. Most men find taking the tablet 30-60 minutes before anticipated sexual activity provides optimal timing.

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

Common Side Effects and Safety Considerations

The most frequently reported side effects of sildenafil include headache, facial flushing, indigestion, nasal congestion, and dizziness [2]. These effects are generally mild to moderate and tend to diminish with continued use as your body adjusts to the medication. In clinical trials, fewer than 3% of men discontinued sildenafil due to adverse effects [2].

More serious but rare side effects include sudden vision changes, prolonged erections lasting over 4 hours (priapism), and sudden hearing loss. If you experience any of these, seek immediate medical attention. Men taking nitrate medications for chest pain should never use sildenafil, as the combination can cause a dangerous drop in blood pressure [4].

Your UK prescriber will review your complete medical history during consultation to identify any contraindications. Conditions requiring special consideration include severe cardiovascular disease, recent stroke or heart attack, low blood pressure, liver or kidney impairment, and retinitis pigmentosa. Always disclose all medications and health conditions to ensure safe prescribing.

Alternative Erectile Dysfunction Treatments

While sildenafil remains the most prescribed erectile dysfunction medication in the UK, several alternatives may suit different clinical needs. Tadalafil offers a longer duration of action (up to 36 hours) compared to sildenafil's 4-6 hours, making it popular among men who prefer more spontaneity [5]. Some patients find tadalafil's extended window reduces performance anxiety.

For men who don't respond adequately to oral PDE5 inhibitors, options include vacuum erection devices, intracavernosal injections, or urethral suppositories. Psychological factors often contribute to erectile dysfunction, so cognitive behavioural therapy or psychosexual counselling may complement medication, particularly when anxiety or relationship issues play a role.

Your UK prescriber can discuss all suitable options during consultation. Some men benefit from trying different PDE5 inhibitors to find which works best for their lifestyle and physiology. At Cured Pharmacy, we stock multiple erectile dysfunction treatments including various sildenafil formulations and tadalafil products, giving you and your prescriber flexibility in treatment selection.
