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.

Your Complete Guide to Buying Viagra Online Safely

What is Viagra and How Does It Work?

Viagra is the brand name for sildenafil citrate, a prescription medication used to treat erectile dysfunction in men. It belongs to a class of medicines called PDE5 inhibitors, which work by increasing blood flow to the penis when you're sexually aroused. Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective.

Branded Viagra vs Generic Sildenafil: Your Choice

At EverydayMeds, you can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient and work in exactly the same way. The main difference is cost - generic sildenafil offers the same effectiveness at a lower price point. Many patients opt for the generic version due to excellent value whilst maintaining the same clinical benefits.

Available Dosages and How to Take

Viagra and sildenafil are available in 25mg, 50mg, and 100mg tablets. Most men start with 50mg, taken approximately 30-60 minutes before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if needed. Take only one dose per 24-hour period, and avoid fatty meals which can delay the medication's effectiveness.

Who Can Take Viagra?

Viagra is suitable for adult men over 18 experiencing erectile dysfunction. However, it's not suitable for everyone. You cannot take Viagra if you're using nitrate medications (such as GTN spray), have severe heart problems, very low blood pressure, or severe liver disease. Our online consultation will assess your medical history and current medications to ensure Viagra is safe for you.

The EverydayMeds Process

Buying Viagra online through EverydayMeds is straightforward and confidential. Complete our clinical questionnaire, which is reviewed by UK-licensed prescribers. Once approved, you'll proceed to checkout where you can select either branded Viagra or generic sildenafil. Your medication is dispatched in discreet packaging with tracked delivery options available throughout the UK.

Common Side Effects and Safety

Most men tolerate Viagra well, but some may experience mild side effects including headaches, flushing, indigestion, or nasal congestion. These usually resolve quickly. Serious side effects are rare but require immediate medical attention, such as prolonged erections lasting over 4 hours or sudden vision changes. Always follow dosage instructions and consult our clinical team if you have concerns.

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.
