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 Viagra Works and Treatment Options Available

Understanding Viagra and Sildenafil

Viagra is a prescription-only medicine (POM) containing sildenafil citrate, originally developed by Pfizer for treating erectile dysfunction. The medication belongs to a class of drugs called PDE5 inhibitors, which work by blocking the phosphodiesterase type 5 enzyme. This action increases blood flow to the penis during sexual arousal, helping men achieve and maintain erections suitable for sexual activity.

Treatment Options: Branded vs Generic

EverydayMeds provides patients with choice between branded Viagra and generic sildenafil tablets. Both contain identical active ingredients and demonstrate equivalent effectiveness, with the generic option typically offered at a lower cost. During the online consultation process, patients can select their preferred option based on personal preference and budget considerations.

Dosage and Administration Guidelines

Viagra and sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before planned sexual activity. Depending on effectiveness and tolerability, the dose may be adjusted to 25mg or increased to a maximum of 100mg. Only one dose should be taken within any 24-hour period.

Eligibility and Safety Considerations

Treatment with Viagra or sildenafil requires completion of a clinical assessment with a UK-licensed prescriber. This evaluation considers cardiovascular health, current medications, and medical history to ensure safe prescribing. The medication is not suitable for men taking nitrate medications, those with severe heart conditions, or individuals with certain other medical conditions that may contraindicate treatment.

Getting Started with Treatment

EverydayMeds offers a convenient online consultation service where patients can complete a comprehensive medical questionnaire reviewed by qualified UK prescribers. Following approval, treatment can be delivered discreetly to your chosen address, with ongoing support available throughout your treatment journey.

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.
