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 Start Your Viagra Treatment with EverydayMeds

What Viagra Actually Does in Your Body

Viagra works by blocking an enzyme called PDE5, which restricts blood flow to the penis. When you take Viagra and become sexually aroused, the medication allows blood vessels to relax and widen, improving blood flow to achieve and maintain an erection. This process typically begins 30-60 minutes after taking the tablet and can remain effective for 4-6 hours, though this doesn't mean you'll have an erection for this entire time.

It's crucial to understand that Viagra doesn't automatically cause erections or increase sexual desire. Sexual stimulation is still required for the medication to work effectively. The treatment simply makes it easier for your body's natural arousal response to function properly.

Starting Your First EverydayMeds Consultation

Your journey begins with our comprehensive online consultation form, completed from the privacy of your home. This clinical assessment covers your medical history, current medications, and specific symptoms to ensure Viagra is safe and suitable for you. Our UK-licensed prescribers review every consultation individually, never using automated approvals for your safety.

The consultation typically takes 5-10 minutes and includes questions about cardiovascular health, as erectile dysfunction can sometimes indicate underlying heart conditions. You'll also be asked about any medications you're taking, particularly nitrates or blood pressure treatments, as these can interact dangerously with Viagra.

Choosing Between Branded Viagra and Generic Sildenafil

During checkout, you'll have the option to select either branded Viagra manufactured by Pfizer or generic sildenafil. Both contain exactly the same active ingredient in identical dosages, offering the same effectiveness and safety profile. The primary difference is cost, with generic sildenafil typically being 60-80% cheaper than the branded version.

Many first-time patients wonder whether generic medications are as effective as branded ones. The answer is yes - generic medicines undergo rigorous testing to prove they're bioequivalent to the original branded product. Your choice often comes down to personal preference and budget considerations.

Understanding Dosage Options for First-Time Users

Viagra and sildenafil are available in three strengths: 25mg, 50mg, and 100mg. Most men start with the 50mg dose, which provides an effective balance between efficacy and tolerability. If you experience side effects or find the dose less effective, your prescriber can adjust this up to 100mg or down to 25mg on subsequent orders.

Remember that you should only take one tablet per 24-hour period, regardless of the strength. Taking the medication 30-60 minutes before sexual activity on a relatively empty stomach typically provides the best results.

What to Expect from Your First Delivery

Once approved, your medication is dispensed from our GPhC-registered UK pharmacy and shipped in completely plain, unmarked packaging. Nothing on the outside indicates the contents, ensuring complete privacy. Standard delivery takes 1-2 working days, with next-day options available if needed.

Your package will include the prescribed tablets, a patient information leaflet with detailed instructions, and information about reordering through your secure online account. We also provide 24/7 access to pharmacist support should you have any questions about your treatment.

Managing Side Effects and Expectations

Common first-dose side effects include headaches, facial flushing, nasal congestion, and mild indigestion. These effects are usually temporary and often reduce with subsequent doses as your body adjusts. Taking the tablet with plenty of water and avoiding large, fatty meals beforehand can help minimise these issues.

It's important to have realistic expectations for your first experience. Some men achieve excellent results immediately, while others may need to try different doses or take the medication several times before finding what works best. This is completely normal and doesn't indicate treatment failure.

When to Seek Immediate Medical Attention

While serious side effects are rare, you should seek emergency medical help if you experience an erection lasting more than four hours, sudden vision or hearing loss, or chest pain during sexual activity. These situations require immediate professional medical attention and should never be ignored.

For less urgent concerns about your treatment, you can contact our pharmacy team through your online account or speak with your GP about adjusting your prescription.

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.
