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.

Viagra vs Sildenafil: Understanding Your Options

What Makes Viagra Different from Generic Sildenafil?

Viagra, manufactured by Pfizer, contains sildenafil citrate as its active ingredient. Generic sildenafil contains exactly the same active ingredient but is produced by different manufacturers once the original patent expired. Both medications work identically by inhibiting the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. The key difference lies in cost rather than clinical effectiveness.

Dosage Options and Effectiveness

Both Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths. Most patients start with the 50mg dose, which can be adjusted based on effectiveness and tolerability. The medication typically begins working within 30-60 minutes and effects may last 4-6 hours. This doesn't mean an erection lasts this duration - sexual stimulation is still required for the medication to work.

Cost Considerations and Value Assessment

When evaluating value, generic sildenafil typically costs significantly less than branded Viagra whilst providing identical clinical benefits. Some patients prefer the branded option for peace of mind, whilst others choose generic sildenafil for cost-effectiveness. At EverydayMeds, patients can choose between both options during checkout following their consultation.

Clinical Consultation Requirements

Both Viagra and sildenafil require a prescription following consultation with a UK-licensed prescriber. The clinical assessment evaluates your medical history, current medications, and cardiovascular health to ensure the treatment is suitable. This includes checking for contraindicated medications such as nitrates, which can cause dangerous interactions.

Who May Be Suitable for Treatment

Adult men experiencing erectile dysfunction may be suitable for sildenafil-based treatments. However, the medication isn't appropriate for everyone. Those with severe heart conditions, recent stroke or heart attack, very low blood pressure, or taking certain medications including nitrates should not use these treatments. A thorough medical assessment determines suitability.

Expected Outcomes and Realistic Expectations

Clinical studies show that sildenafil (whether branded Viagra or generic) helps approximately 70-80% of men with erectile dysfunction achieve erections suitable for sexual activity. The medication requires sexual arousal to work and doesn't automatically cause erections. Some men may need dose adjustments to find their optimal strength.

Safety Considerations and Side Effects

Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These are typically mild and temporary. More serious but rare side effects include sudden vision or hearing loss, or prolonged erections lasting over 4 hours, which require immediate medical attention.

Making Your Choice

When deciding between branded Viagra and generic sildenafil, consider your budget, personal preferences, and treatment goals. Both options undergo rigorous quality control and provide equivalent therapeutic benefits. Your prescriber can help you weigh the options based on your individual circumstances and preferences.

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.
