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, Safety & Getting Treatment

How Viagra Works

Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. It works by increasing blood flow to the penis when sexually aroused. Important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.

Dosage Guidelines

Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken 30-60 minutes before sexual activity. Based on effectiveness and how well you tolerate the medication, your prescriber may adjust this to 25mg or increase to 100mg. The maximum dose is one tablet per 24-hour period. Food, particularly fatty meals, can delay how quickly Viagra starts working.

Who Can Take Viagra

Viagra is suitable for adult men aged 18 and over who experience erectile dysfunction. To obtain a prescription, you must complete a clinical assessment with a UK-licensed prescriber who will evaluate your medical history, current medications, and cardiovascular health. This ensures the treatment is safe and appropriate for your individual circumstances.

Important Safety Information

Certain medical conditions and medications make Viagra unsuitable. You should not take Viagra if you use nitrate medications (such as GTN spray or isosorbide), have severe heart disease, recent heart attack or stroke within six months, severe liver problems, or very low blood pressure. Alpha-blockers, some antifungals, and HIV medications can interact with Viagra, so it's essential to declare all current medications during your consultation.

Branded vs Generic Options

EverydayMeds offers both Pfizer's branded Viagra and generic sildenafil. Both contain the same active ingredient and work identically - the generic version typically costs less whilst providing the same therapeutic effect. You can choose between branded or generic options at checkout following your approved consultation.

Getting Treatment

Our service begins with a confidential online consultation where you'll complete a medical questionnaire. A UK-licensed prescriber reviews your information and, if suitable, approves your prescription. Treatment is then dispensed from our UK pharmacy and delivered discreetly to your address. Regular follow-ups ensure ongoing safety and effectiveness of your treatment.

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.
