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.

Cost Comparison & Treatment Options Available

Viagra Tablet Pricing Structure

Viagra tablet costs vary significantly between branded and generic options. EverydayMeds provides transparent pricing for both Viagra (Pfizer's branded version) and Sildenafil (generic equivalent) during checkout. The active ingredient sildenafil citrate remains identical in both formulations, with generic versions typically offering substantial cost savings. NHS guidelines acknowledge that generic medications provide equivalent therapeutic benefits at reduced costs.

Available Dosage Strengths

Both Viagra and Sildenafil are available in 25mg, 50mg, and 100mg tablets. NHS guidance recommends starting with 50mg approximately one hour before sexual activity. Your prescriber may adjust the dose to 25mg if side effects occur, or increase to 100mg if the initial dose proves insufficient. The maximum frequency remains one tablet per 24-hour period regardless of strength chosen.

Clinical Assessment Requirements

NHS guidelines mandate clinical assessment before prescribing sildenafil for erectile dysfunction. EverydayMeds' UK-licensed prescribers evaluate your cardiovascular health, current medications, and medical history during consultation. This assessment ensures treatment safety and identifies potential contraindications such as nitrate medications or severe heart conditions.

Choosing Between Branded and Generic Options

Patients can select between Viagra and Sildenafil based on personal preference and budget considerations. Both formulations contain identical active ingredients and undergo rigorous quality testing. Generic Sildenafil offers equivalent efficacy at lower cost, while some patients prefer branded Viagra for familiarity reasons. Our clinical team can discuss both options during your consultation.

Treatment Duration and Effectiveness

Sildenafil typically begins working within 30-60 minutes and effects may last 4-6 hours. NHS guidance emphasises that sexual stimulation remains necessary for effectiveness, as the medication enhances natural physiological responses rather than causing automatic erections. Taking tablets on an empty stomach may improve onset time compared to consumption with fatty meals.

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.
