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 Dosage & Treatment Options

How Viagra Works for Men

Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. The medication blocks the phosphodiesterase type 5 enzyme, allowing blood vessels to relax and improve circulation. Sexual stimulation is still required - Viagra does not cause automatic erections. Effects typically begin within 30-60 minutes and may last up to 4-6 hours, though this does not mean erections persist throughout this period.

Available Strengths and Starting Doses

Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, taken approximately one hour before sexual activity. Based on effectiveness and tolerability, your prescriber may adjust this to 25mg (if side effects occur) or increase to 100mg (if 50mg proves insufficient). Only one tablet should be taken within any 24-hour period, regardless of strength.

Viagra vs Sildenafil: Branded vs Generic

EverydayMeds offers both Viagra (the original Pfizer brand) and Sildenafil (generic version) containing identical active ingredients. Both require prescription and clinical assessment but generic Sildenafil typically costs significantly less whilst providing equivalent effectiveness. Patients can choose their preferred option during checkout following successful consultation with our UK-licensed prescribers.

Eligibility and Safety Considerations

Viagra is suitable for adult men experiencing erectile dysfunction, following clinical assessment. Our prescribers evaluate cardiovascular health, current medications, and medical history to ensure safe use. Men taking nitrate medications (GTN sprays, heart tablets) cannot use Viagra due to dangerous interactions. Those with severe heart conditions, recent stroke, or very low blood pressure may also be unsuitable for treatment.

Getting Viagra Through EverydayMeds

Our streamlined process involves completing a confidential medical questionnaire reviewed by UK-licensed prescribers. Following approval, patients choose between branded Viagra or generic Sildenafil, with discreet next-day delivery available. All treatments include comprehensive patient information and ongoing support from our qualified pharmacy team.

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.
