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.

Viagra Safety Profile and Value Comparison

Clinical Safety Record

Viagra (sildenafil citrate) has demonstrated a well-established safety profile through extensive clinical trials involving over 4,000 men and real-world use by millions of patients globally. The medication has been available since 1998, providing substantial long-term safety data. When prescribed appropriately following clinical assessment, serious adverse events are uncommon. EverydayMeds ensures patient safety through comprehensive medical evaluations conducted by UK-licensed prescribers before dispensing either branded Viagra or generic sildenafil.

Understanding Side Effects

Common side effects of sildenafil include headache, facial flushing, indigestion, and nasal congestion. These effects are typically mild to moderate and resolve naturally as the medication clears from the system within 4-6 hours. Less common side effects may include dizziness, visual disturbances, or muscle aches. Serious side effects are rare but can include prolonged erections lasting over four hours, sudden vision or hearing loss, or severe allergic reactions requiring immediate medical attention.

Contraindications and Safety Precautions

Viagra is not suitable for all men, which is why prescription assessment is essential. Men taking nitrate medications for heart conditions cannot safely use sildenafil due to potentially dangerous blood pressure interactions. Those with severe cardiovascular disease, recent heart attack or stroke, severe liver impairment, or very low blood pressure require careful evaluation. The clinical assessment process at EverydayMeds identifies these contraindications, ensuring only appropriate candidates receive treatment.

Value Assessment: Viagra vs Sildenafil

Both branded Viagra and generic sildenafil contain identical active ingredients and demonstrate equivalent safety profiles. The generic version typically costs significantly less while maintaining the same effectiveness and safety standards required by the MHRA. Many patients find generic sildenafil provides excellent value without compromising on quality or safety. EverydayMeds offers both options, allowing patients to choose based on personal preference and budget considerations during the checkout process.

Safe Usage Guidelines

Proper usage maximises safety and effectiveness. Take one tablet 30-60 minutes before sexual activity, with a maximum of one dose per 24-hour period. Avoid excessive alcohol consumption, which can increase side effect risk and reduce effectiveness. Fatty meals may delay onset of action. Sexual stimulation is still required for the medication to work effectively. Store tablets in original packaging away from moisture and heat.

Monitoring and Follow-up

Regular review of treatment effectiveness and safety is recommended, particularly for men with underlying health conditions. Patients should report any concerning side effects or changes in their health status to their prescriber. EverydayMeds provides ongoing support and monitoring through follow-up consultations, ensuring continued safe and effective treatment. This monitoring process applies equally to both branded and generic formulations.

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.
