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.

Complete Guide to Viagra Treatment Options

Understanding Viagra vs Sildenafil Options

Viagra contains the same active ingredient as generic sildenafil - sildenafil citrate. The branded Viagra comes from Pfizer, whilst generic sildenafil offers identical therapeutic effects at a lower cost. EverydayMeds provides both options, allowing patients to choose based on personal preference during checkout. Both require the same clinical assessment and prescription process.

How Viagra Works for Erectile Dysfunction

Viagra belongs to a class of medicines called PDE5 inhibitors. When sexually aroused, it helps increase blood flow to the penis by blocking the phosphodiesterase type 5 enzyme. Important to understand that Viagra doesn't cause automatic erections - sexual stimulation remains necessary. The medication simply helps achieve and maintain erections when natural arousal occurs.

Dosage and Administration Guidelines

Starting doses typically begin at 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and tolerability, prescribers may adjust this to 25mg or increase to 100mg. Only one dose should be taken within any 24-hour period. Fatty meals may delay the onset of action, so taking on an empty stomach often provides quicker results.

Safety Considerations and Contraindications

Viagra isn't suitable for everyone. Men taking nitrate medications for heart conditions cannot safely use Viagra due to dangerous blood pressure interactions. Other contraindications include severe heart disease, recent stroke or heart attack, severe liver problems, or very low blood pressure. Our clinical assessment evaluates these factors before prescribing.

Getting Treatment Through EverydayMeds

Our UK-licensed prescribers conduct thorough online consultations to ensure Viagra or sildenafil is appropriate for each patient. This includes reviewing medical history, current medications, and cardiovascular health. Once approved, treatments are dispensed from our UK pharmacy with discreet packaging and reliable delivery options.

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.
