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: How It Works and Effectiveness

What Is Viagra and How Does It Work?

Viagra is the brand name for sildenafil citrate, originally developed by Pfizer. It belongs to a class of medications called PDE5 inhibitors, which work by blocking the phosphodiesterase type 5 enzyme. This action increases blood flow to the penis during sexual arousal, helping men achieve and maintain erections suitable for sexual activity.

It's important to understand that Viagra doesn't cause automatic erections. Sexual stimulation is still required for the medication to be effective. The enhanced blood flow typically begins within 30-60 minutes of taking the tablet, with effects potentially lasting 4-6 hours.

Viagra vs Sildenafil: Understanding Your Options

Many patients wonder about the difference between Viagra and sildenafil. The key distinction is that Viagra is the branded version manufactured by Pfizer, whilst sildenafil is the generic alternative containing the same active ingredient. Both medications work identically and have the same clinical effectiveness.

EverydayMeds offers both Viagra and sildenafil options, allowing patients to choose between branded and generic versions during checkout. The generic sildenafil provides the same therapeutic benefits at a lower cost, making treatment more accessible for many patients.

Available Dosages and Finding the Right Strength

Both Viagra and sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. Most patients begin with the 50mg dose, which can be adjusted based on effectiveness and tolerability. The 25mg dose is often prescribed for patients with certain medical conditions or those taking medications that may interact with sildenafil.

The maximum dose is 100mg, and it's crucial never to exceed one tablet within a 24-hour period. Taking the medication 30-60 minutes before sexual activity typically provides optimal results, though fatty meals may delay the onset of action.

Safety Considerations and Who Shouldn't Take Viagra

Viagra and sildenafil are prescription-only medicines in the UK, requiring consultation with a qualified healthcare provider. This ensures the medication is safe and appropriate for your individual circumstances. Certain conditions and medications make these treatments unsuitable.

Men taking nitrate medications for heart conditions should never use Viagra or sildenafil, as this combination can cause dangerous drops in blood pressure. Similarly, those with severe heart disease, recent stroke or heart attack, or severe liver problems may not be suitable candidates for treatment.

Clinical Assessment and Getting Started

Before prescribing Viagra or sildenafil, healthcare providers conduct a thorough clinical assessment. This evaluation considers your medical history, current medications, cardiovascular health, and the underlying causes of erectile dysfunction. The assessment ensures the medication is both safe and likely to be effective for your situation.

EverydayMeds' UK-licensed prescribers review each consultation carefully, taking into account factors such as age, health status, and any concurrent medical treatments. This personalised approach helps determine the most appropriate treatment option and dosage.

Maximising Treatment Effectiveness

Several factors can influence how well Viagra or sildenafil works for you. Taking the medication on an empty stomach or after a light meal typically provides faster results. Avoiding excessive alcohol consumption is also important, as it can reduce the medication's effectiveness and increase the risk of side effects.

Regular follow-up consultations help monitor treatment progress and make any necessary adjustments to dosage or treatment approach. Many patients find their confidence improves over time as they become more comfortable with their treatment routine.

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.
