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.

Essential Viagra Preparation Checklist

Pre-Consultation Medical Assessment Checklist

Before requesting Viagra treatment, complete this essential medical checklist. First, review your cardiovascular health status, as Viagra affects blood circulation. Note any history of heart attack, stroke, or chest pain within the past six months. Document current blood pressure readings if available, particularly if you have hypotension or uncontrolled hypertension. List any liver or kidney conditions, as these may affect dosing requirements. EverydayMeds offers both branded Viagra and generic sildenafil, with the same safety checklist applying to both options.

Assess your current physical fitness for sexual activity, as this places demands on your cardiovascular system. If you experience chest pain with mild exertion or have severe heart conditions, discuss these thoroughly during your consultation. Document any eye conditions, particularly retinal disorders or previous sudden vision loss, as these may affect treatment suitability.

Medication Interaction Safety Checklist

Create a comprehensive list of all current medications, including prescription drugs, over-the-counter medicines, and herbal supplements. Pay particular attention to nitrate medications such as GTN spray, isosorbide mononitrate, or any chest pain medications, as combining these with Viagra can cause dangerous blood pressure drops. Check for alpha-blocker medications like tamsulosin or doxazosin, commonly prescribed for prostate conditions, which may require dose adjustments.

Review any blood pressure medications, HIV treatments, antifungal medicines, or antibiotics, as these can interact with sildenafil. Note recreational substance use, particularly "poppers" containing amyl nitrite, which create potentially fatal interactions with Viagra. Include any depression medications or treatments for pulmonary hypertension in your medication checklist.

Dosage Selection and Usage Checklist

Understanding Viagra dosage options helps optimise your treatment plan. The standard starting dose is 50mg, with options to adjust to 25mg for those requiring lower doses due to age or medical conditions, or 100mg for enhanced effectiveness. Plan timing carefully, taking Viagra 30-60 minutes before anticipated sexual activity. Remember the maximum frequency is once per 24-hour period, regardless of whether you choose branded Viagra or generic sildenafil.

Consider meal timing in your usage checklist. High-fat meals can delay Viagra's effectiveness, so plan lighter meals or take on an empty stomach for optimal results. Moderate alcohol consumption is generally acceptable, but excessive drinking can reduce effectiveness and worsen side effects. Grapefruit products should be avoided as they can increase sildenafil levels unpredictably.

Side Effect Recognition and Management Checklist

Familiarise yourself with common side effects to expect and manage appropriately. Headaches affect many users initially but often diminish with continued use. Facial flushing, nasal congestion, and mild indigestion are typical reactions that usually resolve within hours. Visual changes, including a blue tinge or light sensitivity, are generally temporary and harmless.

Identify serious side effects requiring immediate medical attention. Priapism, an erection lasting over four hours, constitutes a medical emergency requiring urgent treatment. Sudden vision or hearing loss demands immediate medical evaluation. Chest pain during or after sexual activity requires stopping activity and seeking emergency care. Severe allergic reactions with difficulty breathing, facial swelling, or widespread rash need immediate treatment.

Storage and Safety Protocol Checklist

Establish proper storage procedures for your Viagra supply. Store tablets below 30°C in their original packaging to protect from moisture and light. Keep medication secure and away from children or others who might access it inappropriately. Check expiry dates regularly and dispose of expired medication safely through pharmacy return schemes.

Never share Viagra with others, even if they have similar symptoms, as individual medical assessments determine safety and suitability. Maintain honest communication with your prescriber about effectiveness and any side effects experienced. Report any changes in your health status, new medications, or concerns about treatment response. Whether using branded Viagra or choosing generic sildenafil through EverydayMeds, these safety protocols remain equally important for optimal treatment outcomes.

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.
