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

Standard Dosing Guidelines

The typical starting dose for Viagra is 50mg, taken approximately 30-60 minutes before anticipated sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg proves insufficient. Never exceed one dose in any 24-hour period, regardless of the strength prescribed.

How to Take Viagra Tablets

Swallow the tablet whole with a glass of water. You can take Viagra with or without food, though fatty meals may delay its onset of action. The medication typically begins working within 30-60 minutes, with effects lasting up to 4-6 hours. This doesn't mean you'll have an erection for this duration - sexual stimulation is still required for the medication to work.

Factors Affecting Effectiveness

Several factors can influence how well Viagra works. Alcohol consumption may reduce effectiveness and increase the risk of side effects like dizziness or low blood pressure. Large or fatty meals can delay absorption, so consider taking the medication on an empty stomach for faster results. Stress, anxiety, and underlying health conditions may also impact effectiveness.

What to Expect

Viagra doesn't cause automatic erections - it enhances your body's natural response to sexual stimulation by improving blood flow to the penis. You should notice improved ability to achieve and maintain erections within the 4-6 hour window after taking the medication. If you don't see results after several attempts, consult your prescriber about adjusting the dose.

Safety Considerations

Never combine Viagra with nitrate medications (such as GTN spray) as this can cause dangerous drops in blood pressure. Inform your prescriber about all medications you're taking, including over-the-counter drugs and supplements. If you experience an erection lasting more than 4 hours, seek immediate medical attention.

Branded vs Generic Options

EverydayMeds offers both Viagra (the branded version) and sildenafil (the generic equivalent). Both contain the same active ingredient and work identically, with sildenafil typically being the more cost-effective option. You can choose your preference during checkout after completing your online consultation with one of our UK-licensed prescribers.

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.
