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 Sildenafil and Viagra: The Key Differences

What Makes Sildenafil and Viagra Essentially the Same

Sildenafil and Viagra contain the exact same active pharmaceutical ingredient - sildenafil citrate. This PDE5 inhibitor works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain erections suitable for sexual activity. Both medications are available in identical strengths: 25mg, 50mg, and 100mg tablets, with the same dosing instructions and timing recommendations.

The Primary Advantage of Generic Sildenafil

The most significant difference between generic sildenafil and branded Viagra is cost. Generic medications typically cost substantially less than their branded counterparts because manufacturers don't need to recoup research and development costs. For men requiring long-term erectile dysfunction treatment, choosing generic sildenafil could result in considerable savings over time whilst receiving identical therapeutic benefits.

Clinical Effectiveness and Safety Profile

Extensive clinical studies demonstrate that generic sildenafil provides equivalent effectiveness to branded Viagra. Both medications work within 30-60 minutes when taken on an empty stomach, with effects potentially lasting 4-6 hours. The side effect profile remains identical, with common effects including headaches, facial flushing, indigestion, and nasal congestion. Serious side effects are rare but require immediate medical attention.

Choosing Between Options at EverydayMeds

EverydayMeds offers both Viagra and generic sildenafil options, allowing patients to choose based on personal preference and budget considerations. Some men prefer branded Viagra for peace of mind, whilst others opt for generic sildenafil for cost savings. During our clinical assessment process, our UK-licensed prescribers can discuss which option might be most appropriate for your individual circumstances.

Clinical Assessment and Safety Considerations

Regardless of whether you choose branded or generic sildenafil, the same safety considerations apply. Both medications require prescription following thorough clinical assessment, evaluating cardiovascular health, current medications, and medical history. Certain conditions and medications, particularly nitrates used for chest pain, create dangerous interactions requiring alternative treatments.

Making Your Decision

When deciding between sildenafil and Viagra, consider that both offer identical therapeutic outcomes. If cost is a primary concern, generic sildenafil provides excellent value whilst maintaining the same quality and effectiveness. However, if brand preference matters to you, Viagra remains available as an option through our service.

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.
