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.

How to Access Viagra Treatment Through EverydayMeds

Understanding How Viagra and Sildenafil Work

Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, your body naturally releases nitric oxide in the penis, which triggers the production of cyclic GMP. This chemical helps relax blood vessels and increase blood flow to create an erection. However, an enzyme called phosphodiesterase type 5 (PDE5) breaks down cyclic GMP, which can interfere with this process.

Sildenafil works by temporarily blocking the PDE5 enzyme, allowing cyclic GMP levels to remain elevated for longer periods. This helps maintain improved blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection. It's important to understand that sildenafil doesn't create automatic erections – sexual arousal is still required for the medication to be effective.

Starting Your Online Consultation Process

Accessing Viagra or sildenafil through EverydayMeds begins with our comprehensive online consultation service. Our UK-licensed prescribers will review your medical history, current medications, and overall health status to determine if sildenafil-based treatment is suitable for you. The consultation process typically takes 5-10 minutes and covers essential safety questions about your cardiovascular health, blood pressure, and any medications you're currently taking.

During the assessment, you'll be asked about your experience with erectile dysfunction and any previous treatments you may have tried. This information helps our prescribers recommend the most appropriate starting dose, which is typically 50mg taken approximately one hour before sexual activity. The consultation ensures that sildenafil won't interact with any existing medications or medical conditions.

Choosing Between Branded Viagra and Generic Sildenafil

One of the key advantages of using EverydayMeds is the flexibility to choose between branded Viagra and generic sildenafil at checkout. Both options contain exactly the same active ingredient – sildenafil citrate – and work in identical ways. The primary difference lies in the cost, with generic sildenafil typically offering significant savings compared to the branded version.

Generic sildenafil undergoes the same rigorous testing and quality standards as branded Viagra, ensuring equivalent safety and effectiveness. Many patients find that choosing the generic option allows them to access the same clinical benefits whilst reducing their monthly treatment costs. Our prescribers can provide guidance on both options during your consultation, helping you make an informed decision based on your preferences and budget.

Dosage Options and Treatment Guidance

Sildenafil is available in three main strengths: 25mg, 50mg, and 100mg tablets. Most patients begin with the 50mg dose, which can be adjusted based on effectiveness and any side effects experienced. The medication should be taken approximately 30-60 minutes before sexual activity, and effects typically last for 4-6 hours. It's crucial to remember that only one dose should be taken within any 24-hour period.

Food intake can affect how quickly sildenafil works, particularly heavy or fatty meals, which may delay the onset of effects. For optimal results, many patients find taking the medication on an empty stomach or after a light meal works best. Our prescribers provide detailed guidance on timing and dosage adjustments during your consultation and throughout your treatment journey.

Safe Usage and Potential Side Effects

Like all medications, sildenafil can cause side effects, though many patients experience none or only mild effects. Common side effects may include headaches, flushing, nasal congestion, or mild digestive upset. These effects are usually temporary and tend to diminish as your body adjusts to the medication. More serious side effects are rare but require immediate medical attention, such as prolonged erections lasting more than four hours or sudden vision changes.

Sildenafil is not suitable for everyone, particularly those taking nitrate medications for heart conditions, as this combination can cause dangerous drops in blood pressure. Our consultation process identifies these potential interactions and ensures safe prescribing practices. Patients with certain cardiovascular conditions, severe liver problems, or those taking specific medications may require alternative treatment approaches.

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.
