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.

Safe Administration of Viagra: Step-by-Step Instructions

When and How to Take Viagra

Viagra should be taken approximately 30-60 minutes before sexual activity. The tablet should be swallowed whole with water and can be taken with or without food, though fatty meals may delay its onset of action. The medication works best on an empty stomach or after a light meal. Sexual stimulation is still required as Viagra does not cause automatic erections but enhances the natural response to arousal.

Dosage Guidelines and Safety Limits

The typical starting dose is 50mg, which may be adjusted by your prescriber to 25mg or 100mg depending on effectiveness and any side effects experienced. It's crucial never to exceed one tablet within any 24-hour period, regardless of the strength. Taking more than the recommended dose significantly increases the risk of serious side effects without improving effectiveness.

Important Safety Considerations

Before taking Viagra, ensure you're not taking nitrate medications such as GTN spray or isosorbide, as this combination can cause a dangerous drop in blood pressure. Limit alcohol consumption as it can reduce the medication's effectiveness and increase the likelihood of side effects. If you experience chest pain during sexual activity, stop immediately and seek medical attention.

Maximising Effectiveness

For optimal results, maintain a relaxed mindset and avoid stress, which can interfere with the medication's effectiveness. Regular exercise and a healthy lifestyle may improve overall results. If Viagra doesn't work effectively on the first attempt, speak with your healthcare provider rather than increasing the dose independently.

EverydayMeds Pharmacy Options

At EverydayMeds, patients can choose between Viagra (branded) or Sildenafil (generic) at checkout. Both contain the same active ingredient and work identically, with Sildenafil offering a more cost-effective alternative. Our UK-licensed prescribers will determine the most suitable option and dosage following a comprehensive clinical assessment of your medical history and current health status.

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.
