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.

How to Access Sildenafil Treatment Safely Online

Getting Started with Your Online Consultation

Accessing sildenafil treatment through EverydayMeds begins with completing our comprehensive online medical assessment. Our UK-licensed prescribers review your medical history, current medications, and cardiovascular health to determine if sildenafil treatment is appropriate for you. The consultation process typically takes 5-10 minutes and covers essential safety questions about your general health and any existing medical conditions that might affect treatment suitability.

Understanding Common Sildenafil Side Effects

Most men tolerate sildenafil well, but understanding potential side effects helps you make informed treatment decisions. Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These effects are typically mild and temporary, often decreasing as your body adjusts to the medication. More serious side effects are rare but can include sudden vision or hearing changes, chest pain, or prolonged erections lasting over four hours. If you experience any concerning symptoms, seek immediate medical attention.

Dosage Options and Pricing Information

Sildenafil is available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose for most patients. Your prescriber may adjust the dosage based on effectiveness and any side effects experienced. EverydayMeds offers competitive UK pricing for both generic sildenafil and branded Viagra options, allowing you to choose the treatment that best fits your budget and preferences. Both medications contain the same active ingredient and work identically in your body.

Important Safety Considerations

Sildenafil cannot be taken safely with certain medications, particularly nitrates used for heart conditions, as this combination can cause dangerous drops in blood pressure. During your consultation, you must declare all current medications, including over-the-counter treatments and supplements. Men with recent heart attacks, strokes, or severe cardiovascular conditions may not be suitable candidates for sildenafil treatment. Your prescriber will assess these factors during the consultation process.

Treatment Effectiveness and Expectations

Sildenafil typically works within 30-60 minutes of taking and can remain effective for 4-6 hours, though this doesn't mean erections last this duration. The medication requires sexual stimulation to work effectively and won't cause automatic erections. Taking sildenafil with heavy or fatty meals may delay its onset of action. Most men find the treatment effective, but individual responses can vary, and your prescriber may recommend dosage adjustments if needed.

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.
