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 Dosage and Administration Guidelines

Standard Dosage Recommendations

The typical starting dose for Viagra is 50mg, taken approximately 30-60 minutes before planned sexual activity. Based on individual response and tolerability, your prescriber may adjust this to 25mg for those experiencing side effects or 100mg if the 50mg dose proves insufficient. It's crucial to never exceed one tablet within a 24-hour period, regardless of the strength prescribed.

Optimal Timing and Food Considerations

Viagra should be taken on an empty stomach or after a light meal for best results. Heavy or fatty meals can significantly delay the medication's onset of action, potentially reducing its effectiveness. The medication typically begins working within 30-60 minutes and effects may last up to 4-6 hours, though this doesn't mean an erection will persist for this duration.

Important Safety Precautions

Before taking Viagra, ensure you're not using any nitrate medications such as GTN spray or isosorbide tablets, as this combination can cause dangerous drops in blood pressure. Always inform your healthcare provider about all current medications, including over-the-counter drugs and supplements. If you experience chest pain, dizziness, or prolonged erections lasting more than 4 hours, seek immediate medical attention.

Generic Sildenafil vs Branded Viagra

EverydayMeds offers both branded Viagra and generic sildenafil tablets. Both contain the same active ingredient (sildenafil citrate) and work identically. Generic sildenafil provides a cost-effective alternative whilst maintaining the same safety profile and effectiveness. Patients can choose between branded or generic options during the checkout process based on personal preference and budget considerations.

Consultation and Prescription Process

All sildenafil medications, whether branded Viagra or generic alternatives, require a prescription following consultation with a UK-licensed prescriber. Our online assessment evaluates your medical history, current medications, and overall health to ensure safe prescribing. This process helps identify any contraindications and determines the most appropriate dosage for your individual circumstances.

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.
