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 Long Viagra Effects Last

Viagra typically remains effective for 4-6 hours after taking a dose. This doesn't mean you'll have a continuous erection for this period - rather, the medication helps you achieve and maintain erections when sexually aroused during this timeframe. The active ingredient sildenafil citrate reaches peak levels in your bloodstream within 30-60 minutes of taking the tablet, with effects gradually diminishing over the following hours.

Begin Your Online Consultation Process

EverydayMeds makes accessing ED treatment straightforward through our comprehensive online consultation service. Our UK-licensed prescribers assess your medical history, current medications, and specific symptoms to determine the most suitable treatment approach. You can choose between branded Viagra or the generic alternative sildenafil during checkout - both contain the same active ingredient but sildenafil offers a more cost-effective option.

Factors Affecting Viagra Duration

Several factors may influence how long Viagra remains effective in your system. Age, general health, liver function, and other medications can all impact the duration of effects. Additionally, consuming large or fatty meals before taking Viagra may delay its onset of action by up to an hour. Understanding these variables helps optimise timing and effectiveness of your treatment.

Starting Doses and Adjustments

Most men begin with a 50mg dose, which can be adjusted to 25mg or 100mg based on effectiveness and any side effects experienced. The maximum recommended dose is 100mg, and you should never take more than one dose within a 24-hour period. Our prescribers evaluate your individual circumstances during the online consultation to recommend the most appropriate starting dose.

Safety Considerations and Contraindications

Viagra isn't suitable for everyone, particularly men taking nitrate medications for heart conditions, those with severe cardiovascular disease, or anyone with specific medical contraindications. Our online assessment carefully reviews your medical history and current medications to ensure Viagra or sildenafil is safe and appropriate for your situation.

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.
