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 Viagra and Sildenafil Effectiveness

How Viagra and Sildenafil Work

Both Viagra and sildenafil contain sildenafil citrate, a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. The medication blocks the phosphodiesterase type 5 enzyme, allowing blood vessels to relax and improve circulation. This enhanced blood flow can help achieve and maintain erections, though sexual stimulation remains necessary for the medication to be effective.

Comparing Branded Viagra vs Generic Sildenafil

The primary difference between Viagra and generic sildenafil lies in branding and cost rather than effectiveness. Both contain identical active ingredients and undergo rigorous quality testing. Generic sildenafil typically costs significantly less than branded Viagra whilst providing the same therapeutic benefits. EverydayMeds offers both options, allowing patients to choose based on personal preference and budget considerations during the checkout process.

Dosage Options and Treatment Expectations

Both medications are available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken 30-60 minutes before sexual activity. The dose may be adjusted to 25mg or 100mg depending on effectiveness and tolerability. Effects typically last 4-6 hours, though this refers to the medication's presence in the system rather than continuous erection duration.

Factors Affecting Treatment Success

Several factors influence how well sildenafil works, including overall health, other medications, and lifestyle factors. Food, particularly fatty meals, can delay the medication's onset. Alcohol may reduce effectiveness and increase side effects. Men with diabetes, heart disease, or other health conditions may experience different results and should discuss their medical history during consultation.

Value Assessment: Making the Right Choice

When comparing treatment options, consider both immediate costs and long-term value. Generic sildenafil provides identical therapeutic benefits at a lower price point, making it an excellent choice for men seeking cost-effective treatment. However, some patients prefer branded Viagra for personal reasons. Both options require the same clinical assessment and prescription process, ensuring safety regardless of choice.

Safety and Contraindications

Both Viagra and sildenafil are contraindicated for men taking nitrate medications, those with severe heart disease, or recent heart attack or stroke history. Common side effects may include headaches, flushing, and nasal congestion. Serious side effects are rare but require immediate medical attention, including prolonged erections lasting over four hours or sudden vision changes.

Getting Started with Treatment

EverydayMeds provides convenient online consultations with UK-licensed prescribers to assess suitability for either Viagra or sildenafil. The clinical assessment evaluates medical history, current medications, and cardiovascular health to ensure safe treatment. Once approved, patients can choose between branded or generic options during checkout, with discreet delivery throughout the UK.

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.
