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.

Getting Viagra or Sildenafil Through EverydayMeds

How Long Viagra Effects Last

Viagra typically remains effective in your system for 4-6 hours after taking a dose. This timeframe refers to the window during which the medication can help you achieve and maintain an erection when sexually aroused. It's important to understand that this doesn't mean you'll have a continuous erection - the medication simply makes it easier to respond to sexual stimulation during this period.

Factors Affecting Duration

Several factors can influence how long Viagra works for you. Age can play a role, as older men may find the effects last longer due to slower metabolism. Your overall health, particularly liver and kidney function, affects how quickly your body processes the medication. Food intake is also significant - taking Viagra after a heavy or fatty meal may delay its onset but could potentially extend its duration. Alcohol consumption can reduce effectiveness and should be limited.

Switching Between Treatment Options

Many men benefit from switching between different ED treatments to find their ideal solution. At EverydayMeds, you can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient (sildenafil citrate) and work identically, but the generic option offers significant cost savings. Some patients prefer the branded version for peace of mind, while others appreciate the affordability of sildenafil without compromising on quality.

Our Online Consultation Process

Getting ED treatment through EverydayMeds is straightforward and completely confidential. Our online consultation takes just a few minutes to complete and covers your medical history, current medications, and treatment preferences. UK-licensed prescribers review every consultation on the same day, ensuring you receive appropriate treatment quickly. The assessment considers factors like cardiovascular health and potential drug interactions to ensure sildenafil-based treatments are suitable for you.

Dosage Options and Flexibility

Both Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths through our service. Most men start with 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and any side effects, your dose may be adjusted up to 100mg or down to 25mg. Remember that only one dose should be taken in any 24-hour period, regardless of strength.

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.
