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.

Understanding Viagra Side Effects Through Online Assessment

Common Viagra Side Effects You Should Know About

Viagra (sildenafil) can cause several side effects that our online assessment carefully evaluates. The most frequently reported side effects include headaches, affecting approximately 16% of users, facial flushing (10%), and nasal congestion (4%). Indigestion and visual disturbances, such as mild colour vision changes, may also occur. During your online consultation, our UK-licensed prescribers assess your likelihood of experiencing these effects based on your medical history and current medications.

Serious Side Effects and Medical Screening

Our comprehensive online assessment specifically screens for factors that could increase your risk of serious side effects. These include sudden vision loss, hearing problems, and prolonged erections lasting more than four hours (priapism). Cardiovascular effects such as chest pain, irregular heartbeat, or significant blood pressure changes require immediate medical attention. The assessment questionnaire identifies patients with heart conditions, recent strokes, or severe liver problems who may face increased risks.

How Our Online Assessment Protects You

EverydayMeds' digital consultation process evaluates your complete medical profile to minimise side effect risks. Our UK-registered clinicians review your responses regarding current medications, particularly checking for dangerous interactions with nitrates (GTN sprays), alpha-blockers, or blood pressure medications. The assessment determines whether you're suitable for the standard 50mg starting dose or require dose adjustments to reduce side effect likelihood. Patients can choose between branded Viagra or generic sildenafil during checkout, both offering identical safety profiles.

Managing Side Effects: Clinical Guidance

The online consultation provides personalised advice on managing potential side effects. Most common effects like headaches or flushing are mild and temporary, typically subsiding within hours. Our prescribers may recommend starting with a lower 25mg dose if you're at higher risk of side effects due to age, kidney problems, or concurrent medications. The assessment also covers timing recommendations, such as avoiding fatty meals that can increase side effect intensity and duration.

Getting Your Prescription Safely Online

Following successful assessment completion, UK-licensed prescribers issue your prescription within hours. The online process ensures you receive appropriate warnings about side effects, drug interactions, and emergency symptoms requiring immediate medical attention. Both Viagra and sildenafil options include comprehensive patient information leaflets detailing side effects, proper usage, and safety precautions. Discreet packaging protects your privacy whilst ensuring you have all necessary safety information for responsible use.

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.
