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.

Comparing Viagra Dosage Strengths and Options

Understanding Viagra Dosage Options

Viagra contains sildenafil citrate, a PDE5 inhibitor that enhances blood flow to facilitate erections when sexually aroused. The medication comes in three strengths: 25mg, 50mg, and 100mg tablets. Healthcare providers typically prescribe 50mg as the initial dose, which proves effective for approximately 70% of men with erectile dysfunction.

The 25mg strength serves as a reduced dose for men who experience side effects with higher strengths or those taking medications that may interact with sildenafil. This lower dose can still provide therapeutic benefits whilst minimising potential adverse effects such as headaches or facial flushing.

When 100mg Strength May Be Considered

The maximum 100mg dose represents the highest safe daily dosage of sildenafil. Healthcare providers may recommend this strength for men who find 50mg insufficiently effective after several attempts. However, increasing the dose also raises the likelihood of experiencing side effects, so careful medical supervision is essential.

Men with diabetes, cardiovascular conditions, or those taking certain medications may require dosage adjustments. Age can also influence effectiveness, with some older patients benefiting from starting with 25mg due to slower medication metabolism.

Branded Viagra vs Generic Sildenafil

EverydayMeds provides both branded Viagra and generic sildenafil options, allowing patients to choose based on their preferences and budget. Both contain identical active ingredients and undergo rigorous quality testing to ensure equivalent therapeutic effects.

Generic sildenafil typically costs significantly less than branded Viagra whilst delivering the same clinical outcomes. The active ingredient, dosage, and effectiveness remain identical regardless of whether patients choose the branded or generic version. This flexibility enables men to access effective ED treatment within their preferred price range.

Optimising Treatment Effectiveness

Taking sildenafil 30-60 minutes before planned sexual activity typically provides optimal results. Large or fatty meals can delay absorption, potentially reducing effectiveness. The medication's effects may last 4-6 hours, though this refers to the window of potential effectiveness rather than continuous erection duration.

Sexual arousal remains necessary for the medication to work effectively. Sildenafil enhances the body's natural response to sexual stimulation rather than causing automatic erections. Men should allow adequate time for the medication to take effect and maintain realistic expectations about timing.

Professional Medical Assessment

UK regulations require prescription oversight for both branded Viagra and generic sildenafil. EverydayMeds ensures all patients complete comprehensive medical assessments with UK-licensed prescribers before receiving treatment. This evaluation considers cardiovascular health, current medications, and medical history to determine appropriate dosaging.

The assessment process helps identify potential contraindications, such as nitrate medications or severe heart conditions, which could make sildenafil unsafe. Healthcare providers can recommend the most suitable starting dose based on individual health factors and treatment goals.

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.
