Sildenafil Tablet Quick Reference Guide

If you're researching sildenafil tablets UK online pharmacy options, you'll find transparent pricing, expert clinical guidance, and genuine UK-licensed medication at Cured Pharmacy. As a GPhC-registered pharmacy (9012511), we've helped thousands of UK men access effective erectile dysfunction treatment with complete discretion and professional support from our superintendent pharmacist Tarun Kumar (GPhC 2233073).

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 facilitate increased blood flow during sexual stimulation [1]. The medication does not cause spontaneous erections — sexual arousal is still required for the treatment to be effective.

Clinical trials have demonstrated that sildenafil significantly improves erectile function in approximately 70-80% of men with erectile dysfunction across various underlying causes, including diabetes, cardiovascular disease, and psychological factors [1][2]. The medication typically begins working within 30-60 minutes of administration, with peak plasma concentrations reached around one hour after dosing.

It's important to understand that sildenafil treats the symptoms of erectile dysfunction but does not address underlying causes. Your UK prescriber will assess whether additional investigations or lifestyle modifications may benefit your long-term sexual health during your clinical consultation.

Sildenafil Dosage Guide: 25mg, 50mg, and 100mg Explained

The standard starting dose for most men is sildenafil 50mg, taken approximately one hour before anticipated sexual activity [2]. Based on individual response and tolerability, your prescriber may adjust this to 25mg (for those with certain medical conditions or taking interacting medications) or increase to 100mg for enhanced efficacy.

Sildenafil should not be taken more than once in a 24-hour period, regardless of dose strength. The medication can be taken with or without food, though high-fat meals may delay absorption and reduce effectiveness [3]. Many patients find that taking sildenafil on an empty stomach produces more predictable results.

Adjusting Your Sildenafil Dose Safely

Dose adjustments should only be made under the guidance of a UK prescriber. If you find the 50mg dose ineffective after trying it on at least four separate occasions, your prescriber may recommend increasing to 100mg. Conversely, if you experience bothersome side effects, a reduction to 25mg may be appropriate whilst maintaining therapeutic benefit.

Sildenafil vs Tadalafil: Choosing the Right ED Treatment

Whilst both sildenafil and tadalafil are PDE5 inhibitors licensed in the UK for erectile dysfunction, they differ significantly in their duration of action. Sildenafil remains effective for approximately 4-6 hours, making it suitable for planned sexual activity [1]. Tadalafil, by contrast, can remain active for up to 36 hours, offering greater spontaneity.

The choice between these treatments depends on your lifestyle, frequency of sexual activity, and personal preference. Men who engage in sexual activity more than twice weekly often prefer tadalafil's longer duration, whilst those seeking on-demand treatment may favour sildenafil's shorter action window and lower cost profile.

At Cured Pharmacy, we offer both sildenafil tablets and various tadalafil formulations. Your UK prescriber will discuss which option best suits your individual circumstances during your free online consultation, which typically takes under three minutes to complete.

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
Cialis (Tadalafil) Tadalafil Up to 36 hours From £53.00

Common Sildenafil Side Effects and Safety Considerations

The most frequently reported side effects of sildenafil include headache (occurring in approximately 16% of users), facial flushing (10%), and indigestion (7%) [2][3]. These effects are generally mild to moderate and tend to diminish with continued use as your body adjusts to the medication.

Less common but notable side effects include nasal congestion, visual disturbances (such as a blue tinge to vision or increased light sensitivity), and dizziness. These visual changes are temporary and resolve as the medication clears from your system [3].

Serious side effects are rare but require immediate medical attention. Seek urgent care if you experience an erection lasting longer than four hours (priapism), sudden vision loss, or chest pain during sexual activity. Sildenafil is contraindicated in men taking nitrate medications for angina, as the combination can cause dangerous drops in blood pressure [2].

Who Should Not Take Sildenafil

Sildenafil is not suitable for everyone. Men with severe cardiovascular disease, recent stroke or heart attack (within the past six months), uncontrolled hypertension, or severe liver impairment should not use this medication. Your UK prescriber will conduct a thorough medical assessment to ensure sildenafil is safe and appropriate for you before issuing a prescription.

Sildenafil typically begins working within 30-60 minutes of administration, with peak effectiveness around one hour after taking the tablet. Sexual stimulation is required for the medication to produce an erection.
Can I take sildenafil with alcohol?

Yes, sildenafil is the active ingredient in Viagra. Generic sildenafil contains the same active pharmaceutical ingredient at the same dose strengths and is clinically equivalent to branded Viagra, but typically costs significantly less.
How often can I take sildenafil tablets?
Sildenafil should not be taken more than once in a 24-hour period, regardless of dose strength. Taking multiple doses within 24 hours increases the risk of side effects without improving efficacy.

The recommended starting dose for most men is sildenafil 50mg, taken approximately one hour before sexual activity. Your UK prescriber may adjust this based on your medical history and response to treatment.
Can sildenafil cure erectile dysfunction permanently?
No, sildenafil treats the symptoms of erectile dysfunction but does not cure the underlying condition. The medication provides temporary improvement in erectile function for 4-6 hours after administration.
Are there any long-term side effects of sildenafil?
Long-term studies have shown sildenafil to be safe for extended use when taken as prescribed. Most side effects are temporary and resolve as the medication clears from your system, typically within 24 hours.

What is the difference between sildenafil and Viagra?
Sildenafil is the active ingredient in Viagra, so they work identically to treat erectile dysfunction. The main difference is that generic sildenafil is significantly cheaper than branded Viagra while providing the same effectiveness and safety profile.
Is sildenafil safe to use long term?
