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.

Starting Your Viagra Treatment: What to Expect

How Quickly Does Viagra Work?

Viagra typically begins working within 30-60 minutes of taking the tablet. The medication reaches peak effectiveness approximately one hour after consumption, though this can vary between individuals. Several factors may influence how quickly Viagra works, including whether you've eaten recently, your general health, and the dosage prescribed.

Ordering Viagra Online Through EverydayMeds

Starting your ED treatment is straightforward with our online consultation service. After completing our clinical questionnaire, UK-licensed prescribers review your medical information to ensure Viagra is suitable for you. During checkout, you can choose between branded Viagra or generic sildenafil - both contain the same active ingredient but sildenafil offers a more cost-effective option.

What Affects Viagra's Onset Time?

Food intake significantly impacts how quickly Viagra works. Taking the medication on an empty stomach typically produces faster results, whilst large or fatty meals may delay effectiveness by up to an hour. Alcohol consumption can also affect the medication's performance and may reduce its effectiveness.

Dosage Options for First-Time Users

Most men start with a 50mg dose, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the initial dose proves insufficient. Remember that only one dose should be taken within any 24-hour period.

Duration of Effects

Viagra's effects may last 4-6 hours, though this doesn't mean you'll maintain an erection for this duration. The medication helps you achieve and maintain erections when sexually aroused during this timeframe. Individual responses vary, and some men find the effects diminish after 2-3 hours.

Safety Considerations for New Users

Before prescribing Viagra, our clinicians assess your cardiovascular health and current medications. The medication isn't suitable for men taking nitrate medications for chest pain, or those with severe heart conditions. Common side effects include headaches, facial flushing, and indigestion, which typically resolve quickly.

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.
