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 Online: Duration & Access Guide

How Long Does Viagra Last?

Viagra typically remains effective for 4-6 hours after taking, though individual response may vary. This timeframe refers to when the medication may help you achieve an erection with sexual stimulation - it doesn't mean you'll have an erection for this entire period. The medication reaches peak effectiveness within 30-60 minutes of taking and gradually reduces over several hours.

Factors Affecting Viagra Duration

Several factors can influence how long Viagra lasts in your system. Age, overall health, and dosage strength all play a role. Food consumption, particularly fatty meals, can delay the onset but may extend duration slightly. Alcohol can reduce effectiveness and should be limited when taking Viagra.

How to Access Viagra Through EverydayMeds

Getting Viagra online through EverydayMeds is straightforward and confidential. Start by completing our online consultation form, which asks about your medical history, current medications, and erectile dysfunction symptoms. Our UK-licensed prescribers review your information within hours, ensuring the treatment is suitable and safe for you.

During checkout, you can choose between branded Viagra or Sildenafil (the generic alternative). Both contain the same active ingredient - sildenafil citrate - but generic options offer significant cost savings whilst maintaining the same effectiveness and safety profile.

Online Consultation Process

Our clinical assessment covers your cardiovascular health, current medications, and medical history. This ensures Viagra is safe for you, particularly if you take other medications or have underlying health conditions. The consultation typically takes 5-10 minutes to complete, and you'll receive a decision within 24 hours on weekdays.

Dosage Options Available

EverydayMeds offers Viagra in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may recommend adjusting the dose based on effectiveness and any side effects experienced. Remember, only take one dose per 24-hour period.

Maximising Treatment Duration

To get the most from your treatment, take Viagra on a relatively empty stomach when possible. Avoid excessive alcohol, as this can reduce effectiveness. The medication works best when you're sexually aroused - it enhances natural responses rather than creating automatic erections.

Safety Considerations

Viagra isn't suitable for everyone. Men taking nitrate medications (such as GTN spray) cannot use Viagra due to dangerous interactions. Those with severe heart conditions, recent stroke, or very low blood pressure require careful assessment. Our prescribers evaluate these factors during consultation to ensure your safety.

Cost-Effective Treatment Options

Choosing generic Sildenafil can significantly reduce treatment costs whilst providing identical results to branded Viagra. Both options are available through our service, allowing you to select based on your preferences and budget. All medications are sourced from UK-licensed suppliers and undergo the same quality checks.

Discreet Delivery Service

Once approved, your medication ships in plain packaging with next-day delivery available across the UK. Our service is completely confidential, with discrete billing and packaging that doesn't reveal contents. You can also opt for click-and-collect from selected locations if preferred.

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.
