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.

Evidence-Based Facts About Sildenafil Treatment

Myth 1: Sildenafil Causes Instant, Automatic Erections

One of the most persistent misconceptions is that sildenafil tablets work like a switch, instantly producing erections. In reality, sildenafil is a PDE5 inhibitor that increases blood flow to the penis only when you're sexually aroused. The medication typically takes 30-60 minutes to become effective, and sexual stimulation remains necessary for it to work. Think of sildenafil as removing a roadblock rather than pressing an accelerator.

Myth 2: Generic Sildenafil Is Less Effective Than Viagra

Some patients believe that branded Viagra is superior to generic sildenafil tablets, but both contain identical active ingredients. The difference lies primarily in cost and packaging. UK regulations ensure that generic medications meet the same stringent quality standards as branded versions. At EverydayMeds, patients can choose between generic sildenafil and branded Viagra at checkout, with both options requiring the same clinical assessment process.

Myth 3: Higher Doses Always Work Better

Many men assume that taking 100mg sildenafil will be more effective than 50mg for everyone. However, the optimal dose varies between individuals based on factors including age, overall health, and other medications. Starting with 50mg is typically recommended, with adjustments made based on effectiveness and tolerability. Taking more than the prescribed dose can increase the risk of side effects without necessarily improving results. The maximum safe frequency is one dose per 24 hours.

Myth 4: Sildenafil Works as an Aphrodisiac

Unlike substances portrayed in popular culture, sildenafil tablets do not increase sexual desire or act as aphrodisiacs. The medication addresses the physical mechanism of achieving erections by improving blood flow, but it cannot create sexual interest or arousal. Men experiencing reduced libido alongside erectile dysfunction may need to explore other treatment options with their healthcare provider.

Myth 5: All Men Can Safely Take Sildenafil

Safety misconceptions can be particularly dangerous. Sildenafil is contraindicated for men taking nitrate medications for heart conditions, as this combination can cause life-threatening drops in blood pressure. Men with severe cardiovascular disease, recent stroke, or certain eye conditions may also be unsuitable candidates. This is why EverydayMeds requires a thorough clinical assessment before prescribing either sildenafil or Viagra.

Myth 6: Food and Alcohol Don't Affect Sildenafil

Contrary to some beliefs, fatty meals can significantly delay sildenafil's onset of action, whilst excessive alcohol can impair its effectiveness and increase side effect risks. For optimal results, consider taking sildenafil tablets on an empty stomach or after a light meal. Moderate alcohol consumption is generally acceptable, but heavy drinking should be avoided.

Understanding Realistic Expectations

Setting appropriate expectations is crucial for treatment success. Sildenafil tablets help approximately 70-80% of men with erectile dysfunction, but individual responses vary. Some men may need dose adjustments or may find that alternative treatments work better for their specific situation. The medication typically remains effective for 4-6 hours, though this doesn't mean erections last this duration.

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.
