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.

Clinical Assessment for Viagra 100mg Prescription

When Doctors Recommend Viagra 100mg

Healthcare professionals typically prescribe Viagra 100mg when patients haven't achieved satisfactory results with lower doses of sildenafil. This maximum strength formulation contains 100mg of sildenafil citrate, the same active ingredient found in generic sildenafil tablets. Medical opinion suggests starting with 50mg initially, with dose adjustment based on effectiveness and tolerability. At EverydayMeds, our prescribers follow NICE guidelines to determine the most appropriate dosage for each patient's circumstances.

Medical Evaluation Process

UK doctors emphasise the importance of thorough cardiovascular assessment before prescribing Viagra 100mg. The clinical consultation evaluates blood pressure, heart conditions, current medications, and potential drug interactions. Particular attention is paid to nitrate medications, which create dangerous interactions with sildenafil. Our online assessment mirrors face-to-face GP consultations, ensuring patients receive the same standard of medical care with the convenience of home delivery.

Branded Viagra vs Generic Sildenafil

Medical professionals often explain that both branded Viagra and generic sildenafil contain identical active ingredients and deliver equivalent therapeutic effects. The choice between branded and generic versions typically comes down to patient preference and cost considerations. Generic sildenafil offers significant savings whilst maintaining the same safety profile and effectiveness. At checkout, EverydayMeds patients can select their preferred option following successful clinical approval.

Safety Considerations and Medical Monitoring

Doctors stress that Viagra 100mg requires careful consideration of contraindications and potential side effects. Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. More serious but rare effects require immediate medical attention. Healthcare professionals recommend starting sexual activity gradually and monitoring response to treatment. Our prescribers provide comprehensive safety information and ongoing support to ensure optimal treatment outcomes.

Treatment Effectiveness and Expectations

Clinical evidence demonstrates that Viagra 100mg can be effective in approximately 70-80% of men with erectile dysfunction when used appropriately. Medical opinion emphasises that sildenafil requires sexual arousal to work effectively and doesn't cause automatic erections. The medication typically begins working within 30-60 minutes and effects may last up to 4-6 hours. Doctors advise that fatty meals can delay onset, whilst alcohol may reduce effectiveness and increase side effect risk.

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.
