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.

Complete Safety Checklist Before Ordering

Step 1: Verify Your Eligibility

Before you can buy Viagra, you must be an adult male (18+) experiencing erectile dysfunction. Our UK-licensed prescribers will assess your suitability during the clinical consultation. You'll need to provide details about your medical history, current medications, and cardiovascular health. This assessment ensures Viagra is safe and appropriate for your individual circumstances.

Step 2: Check for Contraindications

Viagra is not suitable for everyone. You cannot take sildenafil if you're currently using nitrates (GTN spray, isosorbide), riociguat, or have severe heart disease. Other contraindications include recent heart attack or stroke (within 6 months), severe liver problems, or very low blood pressure. Our prescribers will review your medical history to identify any potential risks.

Step 3: Review Drug Interactions

Certain medications can interact dangerously with Viagra. Alpha-blockers used for prostate problems or high blood pressure may cause significant blood pressure drops when combined with sildenafil. Antifungal medications like ketoconazole and some antibiotics can affect how your body processes Viagra. Always disclose all medications, including over-the-counter drugs and supplements, during your consultation.

Step 4: Understand Dosage Guidelines

Viagra is available in 25mg, 50mg, and 100mg strengths. The typical starting dose is 50mg, taken 30-60 minutes before sexual activity. Your prescriber may adjust this based on effectiveness and any side effects you experience. Never exceed one dose in 24 hours, and remember that fatty meals can delay the medication's onset of action.

Step 5: Choose Your Treatment Option

EverydayMeds offers both branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically. The generic version typically costs less while providing the same clinical effectiveness. Our prescribers can help you decide which option best suits your needs and budget during the consultation process.

Step 6: Complete Your Order Safely

Once approved, your medication will be dispensed by our UK-registered pharmacy and delivered discreetly to your address. All orders include clear instructions for use, information about potential side effects, and guidance on when to seek medical attention. Our clinical team remains available for ongoing support and medication reviews as needed.

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.
