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.

Pre-Treatment Safety Checklist for Viagra

Medical Assessment Requirements

Before starting Viagra, men must complete a comprehensive clinical assessment with a UK-licensed prescriber. This evaluation covers cardiovascular health, current medications, and medical history to determine suitability. The assessment identifies potential contraindications such as heart conditions, recent stroke, or severe liver problems. Men taking nitrates for chest pain cannot safely use Viagra due to dangerous blood pressure interactions. EverydayMeds conducts thorough consultations before prescribing either branded Viagra or generic sildenafil, ensuring patient safety remains paramount.

Medication Interaction Checklist

Checking current medications prevents potentially dangerous interactions with Viagra. Nitrates including GTN spray and isosorbide tablets create life-threatening blood pressure drops when combined with sildenafil. Alpha-blockers for prostate problems may cause dizziness when taken alongside Viagra. HIV medications, certain antibiotics, and antifungal treatments can increase sildenafil levels in the blood. Men should list all prescription medications, over-the-counter treatments, and recreational substances during their consultation. This includes avoiding 'poppers' containing amyl nitrite which can cause severe complications.

Timing and Preparation Guidelines

Optimal Viagra timing significantly affects effectiveness and safety. Take the tablet 30-60 minutes before planned sexual activity, allowing adequate absorption time. Avoid large or fatty meals beforehand as these delay the medication's onset of action. The maximum dose is one tablet per 24-hour period regardless of effectiveness. Plan for potential side effects including headaches, facial flushing, or mild dizziness during the first few uses. Men should avoid excessive alcohol consumption which can reduce effectiveness and worsen side effects. Starting with the prescribed dose allows assessment of individual response before any adjustments.

Health Condition Considerations

Certain health conditions require special consideration before using Viagra. Men with diabetes, heart disease, or high blood pressure need careful monitoring during treatment. Those with Peyronie's disease or anatomical penile abnormalities may require modified dosing approaches. Kidney or liver problems can affect how the body processes sildenafil, potentially requiring dose adjustments. Recent surgery, particularly cardiovascular procedures, may necessitate treatment delays until full recovery. Men should ensure they're physically capable of sexual activity before starting Viagra, as intimacy places demands on the cardiovascular system.

Emergency Situation Awareness

Recognising emergency symptoms ensures prompt medical attention when needed. Priapism, an erection lasting longer than four hours, requires immediate emergency treatment to prevent permanent damage. Sudden vision or hearing loss during treatment needs urgent medical evaluation. Chest pain occurring during or after sexual activity should prompt immediate cessation of activity and medical consultation. Severe allergic reactions including difficulty breathing, facial swelling, or widespread rash need emergency intervention. Men experiencing these symptoms should seek immediate medical help rather than waiting for symptoms to resolve naturally.

Dosage and Product Selection

Viagra is available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose for most men. The prescriber may adjust the dose based on effectiveness and tolerability during follow-up consultations. EverydayMeds offers both branded Viagra and generic sildenafil containing identical active ingredients at different price points. The generic version provides the same effectiveness and safety profile as the branded product whilst offering cost savings. Men can discuss their preference during consultation, with both options requiring the same clinical assessment and safety considerations before prescription approval.

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.
