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 Long Does Viagra Typically Work?

Viagra's effects generally last between 4-6 hours after taking the medication, though this varies between individuals. The medication typically begins working within 30-60 minutes of consumption, with peak effectiveness occurring around 1-2 hours after taking. It's important to understand that Viagra doesn't cause continuous erection during this period - sexual stimulation is still required for the medication to work effectively.

Complete Your Online Assessment in Minutes

Starting your journey with EverydayMeds is straightforward and completely confidential. Our comprehensive online assessment takes most patients under 10 minutes to complete. You'll provide details about your medical history, current medications, and specific concerns about erectile dysfunction. This information helps our UK-licensed prescribers determine if Viagra is suitable for you and recommend the most appropriate dosage.

Choose Between Viagra and Sildenafil Options

During checkout, patients can select between branded Viagra and generic sildenafil - both contain the same active ingredient (sildenafil citrate) and work identically. Many patients opt for sildenafil as a cost-effective alternative, while others prefer the branded option. Our prescribers can advise which option might suit your needs and budget best.

Factors That Influence Viagra's Duration

Several factors may affect how long Viagra works for you personally. Age, overall health, dosage strength, and whether you've eaten recently can all impact the medication's effectiveness and duration. Heavy or fatty meals may delay Viagra's onset of action, so many patients find taking it on an empty stomach or after a light meal works best.

Professional Medical Assessment Process

Our qualified prescribers carefully review each application to ensure Viagra is safe and appropriate for you. They'll consider your cardiovascular health, current medications, and any contraindications. If Viagra isn't suitable, alternative treatments may be recommended. The assessment also determines the most appropriate starting dosage, typically 50mg, which can be adjusted if needed.

Discreet Service and Next-Day Delivery

Once approved, your medication is dispensed by our registered UK pharmacy and delivered in discreet packaging. Most orders qualify for next-day delivery, allowing you to start treatment quickly. Our service maintains complete confidentiality throughout the process, from assessment to delivery.

Safety Considerations and Medical Support

Viagra is generally well-tolerated, but it's not suitable for everyone. Men taking nitrate medications, those with severe heart conditions, or certain other medical conditions shouldn't use Viagra. Our prescribers ensure safe prescribing by thoroughly reviewing your medical background. Ongoing support is available if you have questions about your treatment or experience any 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.
