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.

Quick Access to Viagra Through Online Consultation

Getting Viagra has never been more straightforward. EverydayMeds offers a discreet online consultation service with UK-licensed prescribers who can assess your suitability for erectile dysfunction treatment. Simply complete our confidential medical questionnaire, and if approved, you can choose between branded Viagra or the more cost-effective generic sildenafil - both contain the same active ingredient and work identically.

Understanding Viagra's Timing and Effectiveness

Viagra typically begins working within 30 to 60 minutes after taking the tablet. However, several factors can influence how quickly it becomes effective. Taking Viagra on an empty stomach generally leads to faster absorption, whilst consuming a large or fatty meal beforehand may delay the onset of action by 30 minutes or more.

The medication's effects can last between 4 to 6 hours, though this doesn't mean you'll have an erection for this entire period. Sexual arousal and stimulation are still necessary for Viagra to work effectively. The drug simply enhances your body's natural response when you're sexually excited.

Choosing Between Viagra and Generic Sildenafil

At checkout, EverydayMeds patients can select either branded Viagra from Pfizer or generic sildenafil. Both medications contain identical active ingredients and demonstrate the same effectiveness and safety profile. The primary difference lies in cost - generic sildenafil offers significant savings whilst providing identical therapeutic benefits.

Our prescribers typically recommend starting with a 50mg dose, which can be adjusted to 25mg or 100mg depending on effectiveness and any side effects experienced. Remember, only one dose should be taken within any 24-hour period.

Safety Considerations and Medical Assessment

Before prescribing Viagra or sildenafil, our clinicians conduct a thorough assessment of your cardiovascular health and current medications. Certain medications, particularly nitrates used for chest pain, can cause dangerous interactions with Viagra. Men with recent heart attacks, strokes, or severe liver problems may not be suitable candidates for this treatment.

Common side effects include headaches, facial flushing, and indigestion, which are generally mild and temporary. Our online consultation process ensures you receive appropriate medical guidance tailored to your individual health circumstances.

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.
