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.

Understanding Viagra Treatment in the United Kingdom

How Viagra Works for Erectile Dysfunction

Viagra contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis during sexual arousal. The medication blocks the PDE5 enzyme, which allows blood vessels to relax and improve circulation. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective. The effects typically begin within 30-60 minutes of taking the tablet and can last for 4-6 hours, though this doesn't mean an erection will persist for this duration.

Available Dosage Options

Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted based on effectiveness and tolerability. The dosage may be reduced to 25mg for those who experience side effects or increased to 100mg if the initial dose proves insufficient. Only one tablet should be taken within a 24-hour period, and it's recommended to take Viagra 30-60 minutes before sexual activity. Food, particularly fatty meals, may delay the onset of action.

Branded Viagra vs Generic Sildenafil

At EverydayMeds, patients can choose between branded Viagra manufactured by Pfizer and generic sildenafil. Both medications contain the same active ingredient and are equally effective, with the main difference being cost. Generic sildenafil offers a more affordable alternative whilst maintaining the same quality and efficacy standards. During the consultation process, our clinicians can help you decide which option may be most suitable for your needs and budget.

Eligibility and Clinical Assessment

Viagra is a prescription-only medicine in the UK, requiring consultation with a qualified healthcare professional. The clinical assessment evaluates your medical history, current medications, and cardiovascular health to ensure safe prescribing. Men aged 18 and over who experience erectile dysfunction may be eligible, provided they don't have contraindications. The assessment process at EverydayMeds is conducted by UK-licensed prescribers who follow MHRA guidelines and clinical best practices.

Important Safety Considerations

Certain medical conditions and medications make Viagra unsuitable. Men taking nitrate medications (such as GTN spray for angina) should never use Viagra due to dangerous blood pressure interactions. Other contraindications include severe heart disease, recent heart attack or stroke, severe liver problems, and very low blood pressure. Common side effects may include headache, facial flushing, indigestion, and nasal congestion. Most side effects are mild and temporary, but any concerning symptoms should be reported to a healthcare professional promptly.

Getting Viagra Through EverydayMeds

Our online consultation process makes accessing Viagra treatment convenient and discreet. After completing a detailed medical questionnaire, one of our UK-licensed clinicians will review your information and determine if Viagra is appropriate for you. If approved, you can choose between branded Viagra or generic sildenafil, with discreet delivery to your preferred address. Our service maintains the highest standards of patient confidentiality and clinical safety 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.
