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.

Comparing Duration and Effectiveness Options

How Long Does Viagra Last in Your System?

Viagra typically remains effective for 4-6 hours after taking, though this varies between individuals. The duration depends on several factors including dosage strength, your metabolism, age, and overall health. Higher doses (100mg) may provide longer-lasting effects compared to lower strengths (25mg or 50mg). It's important to understand that Viagra lasting "4-6 hours" doesn't mean you'll have an erection for this entire period - rather, it's the window during which the medication can help you achieve and maintain an erection when sexually aroused.

Viagra Connect Duration and Limitations

Viagra Connect contains 50mg sildenafil and typically lasts around 4 hours. As an over-the-counter option, it offers convenience but lacks the flexibility of prescription treatments. The fixed 50mg dose may not be optimal for everyone - some men require 25mg due to side effects, whilst others benefit from 100mg for better effectiveness. Connect also requires face-to-face pharmacy consultation and isn't suitable for men taking certain medications or with specific health conditions.

Prescription Viagra: Tailored Duration and Dosing

Prescription Viagra offers three strengths (25mg, 50mg, 100mg), allowing healthcare professionals to tailor treatment based on your individual needs and response. Men who find 50mg insufficient can be prescribed 100mg for potentially longer duration and better effectiveness. Conversely, those experiencing side effects can try 25mg whilst still receiving therapeutic benefits. This personalised approach often results in better treatment outcomes compared to the one-size-fits-all approach of over-the-counter options.

Generic Sildenafil: Same Duration, Better Value

Generic sildenafil contains identical active ingredients to branded Viagra, providing the same 4-6 hour duration at significantly lower cost. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, both requiring the same prescription process and clinical assessment. The generic option delivers identical effectiveness, safety profile, and duration whilst offering substantial savings - particularly beneficial for men requiring long-term treatment.

Factors Affecting How Long Viagra Lasts

Several factors influence Viagra's duration in your system. Food intake significantly impacts absorption - fatty meals can delay onset by up to 60 minutes and may reduce peak effectiveness. Alcohol consumption can also diminish effects and delay absorption. Age plays a role, with older men (over 65) often experiencing longer-lasting effects due to slower metabolism. Certain medications, particularly those affecting liver enzymes, can alter how quickly your body processes sildenafil, potentially extending or reducing duration.

Choosing Between Viagra and Viagra Connect

Consider prescription Viagra if you need flexible dosing, have tried Connect without success, take medications that interact with ED treatments, or have health conditions requiring medical supervision. Viagra Connect might suit men seeking convenience for occasional use who are generally healthy and don't take prescription medications. However, the prescription route through EverydayMeds offers comprehensive clinical assessment, ongoing medical support, and access to different strengths plus the cost-effective generic sildenafil option.

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.
