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.

Essential Information About Sildenafil 50mg Treatment

How Sildenafil 50mg Works

Sildenafil 50mg belongs to a class of medications called PDE5 inhibitors. It works by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis when sexually aroused. Importantly, sildenafil does not cause automatic erections - sexual stimulation is still required for the medication to be effective.

Dosage and Administration Guidelines

The 50mg dose is typically the starting point for most men. Take sildenafil 30-60 minutes before sexual activity, with effects lasting 4-6 hours. This does not mean an erection will last this long, but rather that the medication may help achieve erections during this timeframe when sexually stimulated. The maximum dosage is one tablet per 24-hour period.

Who Can Take Sildenafil 50mg

Sildenafil is suitable for adult men over 18 experiencing erectile dysfunction. All patients must complete a clinical assessment with a UK-licensed prescriber before receiving their prescription. This assessment evaluates cardiovascular health, current medications, and medical history to ensure safe treatment.

Important Safety Considerations

Certain individuals should not take sildenafil 50mg. This includes men taking nitrate medications such as GTN spray or isosorbide, those with severe heart disease, recent heart attack or stroke within six months, severe liver problems, or very low blood pressure. Always inform your prescriber about all medications you are currently taking.

Side Effects and Monitoring

Common side effects may include headache, facial flushing, indigestion, or nasal congestion. These are usually mild and temporary. Seek immediate medical attention if you experience chest pain, sudden vision loss, or an erection lasting more than four hours. Most men tolerate sildenafil well when prescribed appropriately.

Branded vs Generic Options

EverydayMeds offers both generic sildenafil and branded Viagra containing the same active ingredient. Patients can choose their preferred option during checkout. Both versions undergo the same rigorous safety standards and clinical assessment process before dispensing.

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.
