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

Getting Viagra treatment starts with completing our comprehensive online consultation. Our UK-licensed prescribers will review your medical history, current medications, and assess your suitability for sildenafil-based treatments. During checkout, you can choose between branded Viagra or the more affordable generic sildenafil - both contain the same active ingredient and offer identical effectiveness.

Common Side Effects of Viagra You Should Know

Most men tolerate Viagra well, but it's important to be aware of potential side effects before starting treatment. Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These effects are typically mild and temporary, occurring as your body adjusts to the medication. Visual disturbances such as a blue tint to vision or increased light sensitivity can occasionally occur but usually resolve quickly.

Dizziness and changes in blood pressure may also occur, particularly when standing up quickly. Our prescribers will discuss your cardiovascular health during consultation to minimise these risks. Most side effects are dose-related, which is why we often start with a 50mg dose that can be adjusted based on your response and tolerability.

Serious Side Effects Requiring Immediate Medical Attention

While rare, some serious side effects require urgent medical care. Priapism - a painful erection lasting more than four hours - needs immediate hospital treatment to prevent permanent damage. Sudden vision or hearing loss, though uncommon, should prompt immediate medical consultation. Severe allergic reactions including swelling, difficulty breathing, or skin reactions also require emergency treatment.

Chest pain or irregular heartbeat during or after sexual activity should be treated as a medical emergency. Our consultation process identifies men at higher risk for these complications through careful cardiovascular assessment.

Drug Interactions and Safety Considerations

Viagra can interact dangerously with certain medications, particularly nitrates used for chest pain. This combination can cause a severe drop in blood pressure. Alpha-blockers for prostate problems may also interact, requiring careful dose timing. Our prescribers will review all your current medications during consultation to identify potential interactions.

Recreational drugs containing nitrates, often called "poppers," should never be combined with Viagra. Excessive alcohol can increase side effects and reduce effectiveness. Our medical team provides detailed guidance on safe use during your consultation.

Who Cannot Take Viagra

Certain medical conditions may make Viagra unsuitable. Severe heart disease, recent stroke or heart attack, very low blood pressure, or severe liver problems are contraindications. Men taking nitrate medications or riociguat cannot safely use sildenafil-based treatments. Our comprehensive consultation ensures treatment is only prescribed when safe and appropriate for your individual circumstances.

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.
