What Will Viagra Do: Prescription vs Connect

Viagra contains sildenafil citrate, a PDE5 inhibitor that may help improve blood flow to the penis when sexually aroused.

Both options contain the same active ingredient but differ in strength, cost, and availability.

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.

How Viagra Works vs Viagra Connect Options

What Viagra Does in Your Body

Viagra contains sildenafil citrate, which works as a PDE5 inhibitor. When you're sexually aroused, it may help increase blood flow to the penis by blocking the enzyme that normally reduces blood flow. This mechanism can help men with erectile dysfunction achieve and maintain erections suitable for sexual activity. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective.

Prescription Viagra vs Viagra Connect

Prescription Viagra offers three strength options (25mg, 50mg, 100mg) following consultation with a prescriber, whilst Viagra Connect is available over-the-counter in 50mg only. The prescription route allows for personalised dosing based on your medical history, current medications, and individual response. EverydayMeds provides access to all prescription strengths through our online consultation service with UK-licensed prescribers.

Branded Viagra vs Generic Sildenafil

Both branded Viagra and generic sildenafil contain the same active ingredient and work identically in your body. The main differences are cost and manufacturer - generic sildenafil typically costs significantly less whilst providing the same therapeutic benefits. At EverydayMeds, you can choose between branded Viagra or generic sildenafil at checkout, allowing you to select based on your preference and budget.

Expected Effects and Timeline

Viagra typically begins working within 30-60 minutes of taking it on an empty stomach. Food, particularly fatty meals, may delay the onset of effects. The medication's effects can last 4-6 hours, though this doesn't mean you'll have an erection for this entire duration. Instead, it means you may find it easier to achieve erections during this window when sexually aroused.

Dosage Considerations

Most men start with 50mg, which can be adjusted to 25mg if side effects occur, or increased to 100mg if the initial dose isn't effective. Only one dose should be taken in any 24-hour period. Our prescribers evaluate your medical history, current medications, and individual needs to recommend the most appropriate starting dose during your online consultation.

Who Can Take Viagra

Viagra is suitable for adult men with erectile dysfunction who pass a clinical assessment. However, it's not appropriate for everyone. Men taking nitrate medications, those with severe heart conditions, or recent stroke/heart attack history may not be suitable candidates. Our consultation process helps identify whether Viagra is appropriate for your individual circumstances and medical history.

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.
