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 Through EverydayMeds

Getting Viagra has never been more straightforward with our regulated UK online pharmacy. Simply complete our confidential medical questionnaire, which takes just 5 minutes. Our UK-licensed prescribers will review your assessment within hours, and if suitable, your medication can be dispatched for next-day delivery. You can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient but sildenafil offers a more affordable option.

Viagra Onset Times and What to Expect

Most men find Viagra begins working within 30-60 minutes of taking the tablet. However, several factors can influence how quickly you notice effects. Taking Viagra on an empty stomach typically results in faster absorption, whilst fatty meals may delay onset by up to 2 hours. The medication requires sexual stimulation to work effectively - it will not cause an automatic erection. Once active, Viagra's effects can last 4-6 hours, providing a suitable window for sexual activity.

Factors That Affect How Quickly Viagra Works

Age can influence onset times, with older men sometimes experiencing slightly longer wait times. Alcohol consumption may also delay effectiveness and reduce the medication's impact. Your dosage plays a role too - our clinicians typically start patients on 50mg, adjusting to 25mg or 100mg based on response and tolerability. Certain medications, particularly those for blood pressure, can interact with Viagra, which is why our clinical assessment is thorough.

Dosing and Timing Recommendations

Take your prescribed dose approximately one hour before planned sexual activity for optimal results. Never exceed one tablet within 24 hours, regardless of whether you chose Viagra or sildenafil. If you find 50mg insufficient, consult our clinicians about adjusting to 100mg rather than taking multiple tablets. Similarly, if you experience side effects, a reduction to 25mg may be appropriate.

Clinical Safety and Online Consultation Process

Our comprehensive medical assessment ensures Viagra is safe for you. We evaluate cardiovascular health, current medications, and medical history before prescribing. Men taking nitrates for heart conditions cannot safely use Viagra due to dangerous interactions. Those with recent heart attacks, strokes, or severe liver problems may also be unsuitable candidates. Our UK-licensed prescribers carefully review each application to ensure patient safety whilst maintaining complete confidentiality throughout the process.

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.
