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 Order Viagra: Your Step-by-Step Guide

Starting Your Viagra Treatment Journey

Ordering Viagra through EverydayMeds begins with our simple online consultation process. Our UK-licensed prescribers will assess your medical history, current medications, and overall health to determine if Viagra is suitable for you. This clinical assessment ensures your safety and helps identify the most appropriate starting dose, typically 50mg.

During checkout, you can choose between branded Viagra or generic sildenafil - both contain the same active ingredient (sildenafil citrate) and work identically. Many patients opt for sildenafil as it offers the same effectiveness at a lower cost, though the choice is entirely yours.

Understanding How Long Viagra Lasts

Viagra's effects typically last 4-6 hours after taking a dose, though this doesn't mean you'll have an erection for this entire duration. The medication works by increasing blood flow to the penis when you're sexually aroused, and this enhanced response capability remains for several hours. Individual factors like age, overall health, food intake, and alcohol consumption can influence duration.

Most men find Viagra begins working within 30-60 minutes of taking it. Taking it on an empty stomach may help it work faster, as fatty meals can delay absorption. Remember, sexual stimulation is still required - Viagra doesn't cause automatic erections.

Dosage Options and Effectiveness

Viagra is available in 25mg, 50mg, and 100mg strengths. Your prescriber will typically recommend starting with 50mg, which can be adjusted based on how well it works and any side effects you experience. The maximum recommended dose is 100mg, and you should never take more than one dose in 24 hours.

Some men find 25mg sufficient, particularly if they experience side effects with higher doses. Others may benefit from 100mg if 50mg doesn't provide adequate results. Your prescriber can adjust your prescription based on your feedback during follow-up consultations.

Safety Considerations and Contraindications

Viagra isn't suitable for everyone. It's particularly important to avoid Viagra if you're taking nitrate medications (such as GTN spray for chest pain), as this combination can cause dangerous drops in blood pressure. Other contraindications include severe heart disease, recent heart attack or stroke, severe liver problems, and very low blood pressure.

Common side effects may include headache, flushing, indigestion, and nasal congestion. These are usually mild and temporary. If you experience chest pain, prolonged erections lasting more than 4 hours, or sudden vision changes, seek immediate medical attention.

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.
