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 Timing Instructions

When to Take Viagra

Take Viagra approximately 30-60 minutes before sexual activity. The medication works best on an empty stomach, though it can be taken with food. Fatty meals may delay the onset of action, so consider timing your dose accordingly. Effects typically last 4-6 hours, though this doesn't mean an erection will persist throughout this period.

Recommended Dosage

The standard starting dose is 50mg, taken as needed. Depending on effectiveness and tolerability, your prescriber may adjust this to 25mg or increase to 100mg. Never exceed one tablet in a 24-hour period, regardless of the strength prescribed. EverydayMeds provides both Viagra (branded) and sildenafil (generic) options at equivalent doses following consultation.

Important Safety Considerations

Viagra requires sexual stimulation to work effectively - it doesn't cause automatic erections. Before taking Viagra, ensure you've disclosed all current medications during consultation, particularly heart medications. Never combine Viagra with nitrates (GTN spray, heart medications) as this can cause dangerous blood pressure drops.

What to Expect

Most men notice effects within 30-60 minutes of taking Viagra. If the medication doesn't work as expected, don't take additional doses. Instead, consult your healthcare provider about adjusting the dose or exploring alternative treatments. Some men require several attempts before finding their optimal dosing schedule.

Getting Viagra in the UK

Viagra requires a prescription following clinical assessment. EverydayMeds offers convenient online consultations with UK-licensed prescribers who can evaluate your suitability for treatment. Patients can choose between branded Viagra or generic sildenafil based on preference and budget considerations.

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.
