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 Effectiveness and Alternatives

How Does Viagra Work?

Viagra contains sildenafil citrate, a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. Clinical studies show that Viagra is effective for approximately 70-80% of men with erectile dysfunction when taken correctly. The medication typically begins working within 30-60 minutes and its effects can last for 4-6 hours, though this doesn't mean an erection will last this entire duration.

Branded Viagra vs Generic Sildenafil

Many patients ask whether generic sildenafil works as effectively as branded Viagra. Both contain identical active ingredients and work in exactly the same way. The main difference lies in cost - generic sildenafil typically costs significantly less than branded Viagra whilst providing equivalent effectiveness. At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout, depending on their preference and budget.

Alternative ED Treatments Available

If Viagra doesn't provide optimal results, several alternatives may be more suitable. Tadalafil (Cialis) offers longer-lasting effects, remaining active for up to 36 hours, making it ideal for men who prefer spontaneity. Vardenafil (Levitra) may work better for men who experience side effects with sildenafil. These medications work similarly to Viagra but have different duration profiles and side effect patterns.

Factors Affecting Viagra's Effectiveness

Several factors can influence how well Viagra works. Taking the medication with fatty foods may delay its onset of action. Alcohol consumption can reduce effectiveness and increase the risk of side effects. Underlying health conditions such as diabetes, cardiovascular disease, or psychological factors may also impact treatment success. Starting with the standard 50mg dose allows for adjustment to 25mg or 100mg based on individual response.

Maximising Treatment Success

To optimise Viagra's effectiveness, take the medication on an empty stomach approximately one hour before sexual activity. Avoid excessive alcohol consumption and maintain realistic expectations - the medication requires sexual arousal to work effectively. If initial treatment isn't successful, consult with healthcare professionals about dosage adjustments or alternative treatments rather than discontinuing ED medication entirely.

When to Consider Alternatives

Men who don't respond well to Viagra might benefit from trying different PDE5 inhibitors or exploring combination approaches. Some patients find that lifestyle modifications, such as regular exercise, stress reduction, and improved sleep, can enhance medication effectiveness. Psychological counselling may also complement medical treatment, particularly when anxiety or relationship issues contribute to erectile dysfunction.

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.
