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 How Viagra Actually Works

The Size Myth: What Viagra Really Does

One of the most persistent myths about Viagra is that it increases penis size or adds inches permanently. This is simply not true. Viagra (sildenafil citrate) is a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. While improved blood flow may help achieve a firmer, fuller erection that feels larger, Viagra does not actually change the physical dimensions of the penis.

How Sildenafil Actually Functions

When sexually aroused, Viagra blocks the PDE5 enzyme that can restrict blood flow to penile tissues. This allows blood vessels to relax and expand, potentially helping men achieve erections closer to their natural maximum size. However, this effect is temporary and only occurs during sexual activity - there are no permanent changes to penis dimensions.

Individual Results May Vary

Every man's response to sildenafil treatment differs based on factors including age, underlying health conditions, cardiovascular fitness, and the severity of erectile dysfunction. Some men may notice their erections feel fuller or more rigid, which could create the perception of increased size, whilst others may experience more modest improvements in erectile function.

Generic vs Branded Options

EverydayMeds offers both Viagra (branded) and sildenafil (generic) at checkout, giving patients choice based on their preferences and budget. Both contain identical active ingredients and work the same way - the generic version simply costs less as it doesn't carry the brand premium. Clinical effectiveness remains equivalent between branded and generic formulations.

Setting Realistic Expectations

Effective ED treatment requires realistic expectations about what medication can achieve. Viagra and sildenafil may help restore erectile function and confidence, but they don't enhance penis size beyond natural dimensions. Men considering treatment should focus on improved erectile quality rather than size expectations when evaluating treatment success.

Choosing the Right Treatment Approach

UK patients can access both Viagra and sildenafil through EverydayMeds following a clinical consultation with licensed prescribers. Starting doses typically begin at 50mg, with adjustments to 25mg or 100mg based on individual response and tolerability. Taking medication 30-60 minutes before sexual activity allows optimal effectiveness, with effects potentially lasting 4-6 hours.

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.
