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 to Access Viagra Treatment Through EverydayMeds

Getting Viagra online through EverydayMeds is straightforward and confidential. Start by completing our clinical questionnaire, which covers your medical history, current medications, and symptoms. A UK-licensed prescriber reviews your consultation within hours, ensuring Viagra is suitable and safe for you. Once approved, you can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient but sildenafil offers significant cost savings.

Understanding How Long Viagra Works

Viagra typically remains active in your system for 4-6 hours after taking a dose. This doesn't mean you'll have an erection for this entire period - you'll still need sexual stimulation to achieve an erection. The medication works by increasing blood flow to the penis when you become aroused. Most men find Viagra starts working within 30-60 minutes of taking it, with peak effectiveness usually occurring around 1-2 hours after consumption.

Factors Affecting Viagra Duration

Several factors influence how long Viagra works for individual men. Age plays a role - older men may find the effects last longer due to slower metabolism. Food intake significantly impacts timing - taking Viagra on an empty stomach leads to faster absorption, whilst fatty meals can delay effectiveness by up to an hour. Alcohol consumption may reduce Viagra's effectiveness and duration. Your overall health, particularly cardiovascular fitness, also affects how well and how long the medication works.

Dosage Options and Effectiveness

EverydayMeds offers Viagra and sildenafil in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg proves insufficient. Remember, you should never take more than one dose in 24 hours, regardless of strength. The 4-6 hour effectiveness window applies to all dosages, though higher doses may provide more consistent results throughout this period.

Cost-Effective Treatment Options

When ordering through EverydayMeds, you can select from both branded and generic options at checkout. Viagra, manufactured by Pfizer, offers the assurance of the original brand. Generic sildenafil contains identical active ingredients at significantly lower cost - perfect for men seeking effective treatment whilst managing expenses. Both options undergo the same rigorous quality standards and provide equivalent effectiveness and duration of action.

Safety Considerations and Side Effects

Whilst Viagra is generally well-tolerated, some men experience mild side effects including headaches, flushing, or indigestion. These typically resolve within the 4-6 hour window as the medication leaves your system. More serious side effects are rare but require immediate medical attention - these include prolonged erections lasting over 4 hours, sudden vision changes, or chest pain. Our online consultation process identifies men who shouldn't take Viagra, including those taking nitrate medications or with severe heart conditions.

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.
