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 Common Viagra Side Effects

Most men tolerate Viagra (sildenafil) well, with side effects typically being mild and temporary. The most frequently reported side effects include headaches (affecting approximately 16% of users), facial flushing, and indigestion. These effects usually diminish as your body adjusts to the medication. At EverydayMeds, our clinical assessment helps identify your suitability for treatment and discusses potential side effects before prescribing.

Complete Side Effects Profile

Common side effects (affecting 1-10% of users) include headaches, dizziness, facial flushing, nasal congestion, indigestion, and visual disturbances such as mild colour vision changes. Uncommon effects (0.1-1% of users) may include rapid heartbeat, changes in blood pressure, nausea, and muscle aches. Rare but serious side effects include priapism (prolonged erection lasting over 4 hours) requiring immediate medical attention, sudden hearing loss, and severe allergic reactions.

Minimising Side Effects and Maximising Value

Starting with the lowest effective dose (typically 25mg or 50mg) helps minimise side effects whilst maintaining effectiveness. Avoiding alcohol, fatty meals, and grapefruit juice can reduce the likelihood of experiencing side effects. Our online consultation allows UK-licensed prescribers to recommend the optimal starting dose based on your health profile. Patients can choose between branded Viagra or generic sildenafil at checkout - both contain identical active ingredients but sildenafil offers significant cost savings.

When to Seek Medical Advice

Contact your prescriber if you experience persistent headaches, dizziness that doesn't improve, or any concerning symptoms. Seek immediate medical attention for priapism (erection lasting over 4 hours), sudden vision or hearing loss, or chest pain during sexual activity. EverydayMeds provides ongoing clinical support through our patient portal, ensuring safe, effective treatment.

Accessing Treatment Through EverydayMeds

Our streamlined online consultation takes 2-3 minutes and includes comprehensive side effect assessment. UK-licensed prescribers review your medical history, current medications, and cardiovascular health before prescribing. Approved medications are dispensed by our UK-registered pharmacy with discreet next-day delivery. Patients can switch between branded Viagra and generic sildenafil based on preference and budget, with clinical guidance available throughout treatment.

Drug Interactions and Safety Considerations

Sildenafil interacts dangerously with nitrate medications (GTN spray, isosorbide), alpha-blockers, and certain antifungal medications. Our clinical assessment identifies potential interactions before prescribing. Men with cardiovascular conditions, recent stroke or heart attack, severe liver problems, or taking specific medications may require alternative treatments. Blood pressure medications may need dose adjustments when starting ED treatment.

Cost-Effective Treatment Options

Generic sildenafil offers identical effectiveness to branded Viagra at significantly reduced cost. Both options undergo rigorous quality testing and contain the same active ingredient (sildenafil citrate). EverydayMeds provides transparent pricing with no hidden fees - consultation, prescription, and delivery costs are clearly outlined. Subscription options offer additional savings for ongoing treatment whilst maintaining clinical oversight.

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.
