How ED treatment works in your body.

Increases blood flow

Increases blood flow

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Understanding Your Treatment Options

What's the Difference Between Sildenafil Citrate and Viagra Connect?

Sildenafil citrate is the generic version of the well-known erectile dysfunction treatment, containing the exact same active ingredient as branded Viagra. This PDE5 inhibitor works by increasing blood flow to the penis when sexually aroused, helping men achieve and maintain erections suitable for sexual activity.

Viagra Connect, launched in 2018, is an over-the-counter version available from UK pharmacies without prescription. However, it's limited to a 50mg dose and requires a consultation with a pharmacist to ensure suitability.

Prescription Strength vs Over-the-Counter Options

Prescription sildenafil citrate offers greater flexibility with three available strengths: 25mg, 50mg, and 100mg. This allows healthcare providers to tailor treatment to individual needs, starting typically with 50mg and adjusting based on effectiveness and tolerability.

The 25mg dose may be more appropriate for older men, those taking certain medications, or individuals who experience side effects with higher doses. Conversely, the 100mg strength provides an option for men who don't achieve adequate results with lower doses.

Viagra Connect is fixed at 50mg, which may not be optimal for everyone. If this dose proves insufficient or causes unwanted side effects, you'd need to consult a prescriber for alternative options anyway.

Cost Considerations and Value

Generic sildenafil citrate typically costs significantly less than branded alternatives while providing identical effectiveness. The active ingredient, manufacturing standards, and therapeutic outcomes remain the same whether you choose branded Viagra or generic sildenafil.

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout, allowing you to select based on personal preference and budget. Both undergo the same rigorous clinical assessment process to ensure safety and suitability.

Clinical Assessment and Safety

Both options require clinical evaluation, but through different pathways. Prescription sildenafil involves consultation with a UK-licensed prescriber who can review your complete medical history, current medications, and cardiovascular health.

This comprehensive assessment is particularly important because sildenafil can interact dangerously with certain medications, especially nitrates used for heart conditions. Men taking GTN spray, isosorbide, or riociguat must not use any form of sildenafil.

The prescription route also allows for ongoing monitoring and dose adjustments, ensuring optimal treatment outcomes while minimising potential risks.

Effectiveness and How They Work

Both sildenafil citrate and Viagra Connect work identically, blocking the PDE5 enzyme to improve blood flow to the penis during sexual arousal. Neither causes automatic erections – sexual stimulation remains necessary for the medication to be effective.

Typically, effects begin within 30-60 minutes of taking the tablet and can last 4-6 hours. This doesn't mean erections persist for this duration, but rather that the medication remains active in your system, allowing for multiple erections during this timeframe when sexually aroused.

Making Your Decision

Consider prescription sildenafil citrate if you value dosing flexibility, comprehensive medical oversight, and cost-effectiveness. This option provides access to the full range of strengths and ongoing medical support to optimise your treatment.

Viagra Connect might suit men who prefer the convenience of pharmacy access and are confident that 50mg is appropriate for their needs. However, remember that if this dose isn't suitable, you'll likely need prescription alternatives anyway.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
