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.

Branded vs Generic: Clinical Differences Explained

Active Ingredient and Mechanism

Both Viagra and generic sildenafil contain sildenafil citrate as their active ingredient. This PDE5 inhibitor works by increasing blood flow to the penis during sexual arousal. The mechanism of action remains identical regardless of whether you choose branded or generic formulation. Clinical studies demonstrate equivalent bioavailability, meaning your body absorbs and processes both medications in the same way.

Effectiveness Comparison

Generic sildenafil delivers the same therapeutic results as branded Viagra. Both formulations typically begin working within 30-60 minutes of taking and may remain effective for 4-6 hours. The starting dose is usually 50mg for both options, which can be adjusted to 25mg or 100mg based on individual response and tolerability. Sexual stimulation is still required for both medications to be effective.

Cost Considerations

The most significant difference lies in pricing. Generic sildenafil typically costs considerably less than branded Viagra, often representing savings of 60-80%. This cost difference exists because generic manufacturers don't need to recoup research and development expenses. For men requiring long-term ED treatment, these savings can be substantial over time.

Quality and Safety Standards

In the UK, both branded and generic medications must meet identical regulatory standards set by the Medicines and Healthcare products Regulatory Agency (MHRA). Generic sildenafil undergoes rigorous testing to ensure it meets the same quality, purity, and potency requirements as Viagra. All formulations available through EverydayMeds are sourced from MHRA-licensed suppliers.

Choosing Your Treatment Option

At EverydayMeds, you can select between Viagra and generic sildenafil during checkout, following successful completion of your clinical assessment. Some men prefer branded medication for peace of mind, whilst others choose generic options for cost-effectiveness. Both require the same safety considerations, including assessment of cardiovascular health and current medications.

Prescription Process

Whether choosing Viagra or sildenafil, you'll complete the same clinical questionnaire reviewed by UK-licensed prescribers. This assessment evaluates your suitability for treatment, considering factors such as current medications, particularly nitrates which create dangerous interactions, cardiovascular health, and medical history. The prescription process ensures safe, appropriate treatment regardless of your choice between branded or generic 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.
