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.

Medical Eligibility Requirements

Before starting Viagra gel treatment, you must meet specific NHS clinical criteria. You should be an adult male experiencing erectile dysfunction who can safely use PDE5 inhibitor medications. The assessment includes reviewing your cardiovascular health, current medications, and medical history. EverydayMeds provides both branded Viagra and generic sildenafil options following your consultation, allowing you to choose based on your preference and budget.

Critical Drug Interaction Checks

Certain medications create dangerous interactions with sildenafil. Never combine Viagra gel with nitrate medications including GTN spray, isosorbide mononitrate, or riociguat for pulmonary hypertension. Alpha-blockers for prostate conditions may cause low blood pressure when combined with sildenafil. Always inform your prescriber about all medications, including over-the-counter drugs and supplements, to avoid potentially serious interactions.

Cardiovascular Health Assessment

Your heart health is crucial when considering Viagra gel. The treatment may not be suitable if you have severe heart disease, recent heart attack or stroke within six months, or very low blood pressure. Sexual activity increases cardiovascular demand, so your prescriber will assess whether your heart can handle this additional stress safely. Be honest about any chest pain, irregular heartbeat, or breathing difficulties during physical activity.

Proper Usage Guidelines

Viagra gel should be used exactly as prescribed by your healthcare provider. The typical starting dose is 50mg, which may be adjusted to 25mg or 100mg based on effectiveness and tolerance. Take the medication 30-60 minutes before anticipated sexual activity, and never exceed one dose in 24 hours. Fatty meals may delay the onset of action, so consider timing your dose accordingly.

Monitoring and Follow-up Requirements

Regular monitoring ensures safe, effective treatment. Report any side effects including headache, flushing, indigestion, or visual disturbances to your prescriber. Seek immediate medical attention for prolonged erections lasting over four hours, sudden vision loss, or chest pain during sexual activity. Your prescriber may schedule follow-up consultations to assess treatment effectiveness and adjust dosing if necessary.

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.
