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.

Common Viagra Misconceptions Explained

Myth 1: Viagra Causes Automatic Erections

Perhaps the most persistent myth about Viagra is that it causes spontaneous erections. This is completely false. Viagra (sildenafil citrate) is a PDE5 inhibitor that works by increasing blood flow to the penis only when sexual arousal occurs. The medication enhances your body's natural response to sexual stimulation - it doesn't replace it. Without arousal, Viagra will not cause an erection. This mechanism makes it a safe and predictable treatment when used correctly.

Myth 2: Generic Sildenafil Is Less Effective

Many patients believe that branded Viagra is superior to generic sildenafil. This misconception stems from brand loyalty rather than medical evidence. Generic sildenafil contains the same active ingredient as Viagra - sildenafil citrate - in identical concentrations. The MHRA ensures that generic medications meet the same rigorous standards for safety, quality and efficacy. At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout, with both options offering equivalent therapeutic benefits at different price points.

Myth 3: Online ED Treatment Is Inherently Unsafe

Concerns about ordering Viagra on the internet are often justified when referring to unlicensed sources. However, legitimate UK online pharmacies like EverydayMeds operate under strict MHRA regulations. Our service requires a comprehensive clinical assessment by UK-licensed prescribers who evaluate your medical history, current medications and cardiovascular health. This ensures the same safety standards as traditional face-to-face consultations. The convenience of online treatment doesn't compromise safety when proper protocols are followed.

Myth 4: ED Only Affects Older Men

Erectile dysfunction is often portrayed as an age-related condition affecting only men over 50. Research indicates that ED can affect men of all ages, with various underlying causes including stress, anxiety, relationship issues, lifestyle factors and medical conditions. Younger men may experience performance anxiety or stress-related ED, whilst others might have underlying health conditions requiring attention. Early intervention can prevent progression and improve quality of life regardless of age.

Myth 5: Viagra Works Immediately and Lasts All Day

Understanding realistic expectations about timing is crucial. Viagra typically takes 30-60 minutes to become effective, with peak effects occurring around one hour after administration. The effects can last 4-6 hours, but this doesn't mean you'll maintain an erection for this duration. Instead, it represents the window during which the medication can facilitate erections when sexual arousal occurs. Fatty meals can delay absorption, whilst alcohol may reduce effectiveness.

Myth 6: Higher Doses Always Work Better

Some patients assume that increasing the dose will improve effectiveness. Sildenafil is available in 25mg, 50mg and 100mg strengths, with 50mg being the typical starting dose. Increasing to 100mg may help some patients, but it also increases the likelihood of side effects without guaranteed improvement. The maximum safe dose is 100mg within 24 hours. Dose adjustments should only occur following consultation with a healthcare provider who can assess your individual response and tolerance.

The Truth About Online Prescriptions

Legitimate online ED treatment requires the same clinical oversight as traditional prescriptions. At EverydayMeds, our assessment process evaluates contraindications such as nitrate medications, recent cardiovascular events, severe liver impairment and other factors that might make sildenafil unsuitable. This thorough approach ensures patient safety whilst providing convenient access to effective treatment.

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.
