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 Instructions and Safety Guidelines

Standard Viagra Dosing Protocol

The recommended starting dose of Viagra is 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the standard dose proves insufficient. EverydayMeds stocks all three strengths and also offers Sildenafil as a cost-effective generic alternative with identical active ingredients.

Timing and Food Considerations

Take Viagra on an empty stomach or after a light meal for optimal absorption. High-fat meals can delay the medication's onset by up to an hour. The effects typically begin within 30-60 minutes and may last up to four hours, though this varies between individuals. Remember that sexual stimulation is still required for the medication to work effectively.

Important Safety Guidelines

Never exceed one dose within 24 hours, regardless of effectiveness. If you take nitrate medications for chest pain or heart conditions, Viagra is contraindicated due to dangerous blood pressure interactions. Always complete an honest medical assessment during your EverydayMeds consultation to ensure safe prescribing.

What to Expect

Viagra doesn't cause automatic erections but enhances your natural response to sexual arousal. Some men notice improved confidence even before physical effects occur. Common mild side effects include headaches, facial flushing, or nasal congestion. If you experience prolonged erections lasting over four hours, seek immediate medical attention.

Choosing Between Viagra and Sildenafil

Both options contain identical sildenafil citrate and work the same way. Viagra is the original branded version, whilst Sildenafil offers the same therapeutic benefits at a lower cost. EverydayMeds presents both choices during checkout, allowing you to select based on your preferences and budget after completing our clinical assessment.

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.
