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.

Comparing Your Viagra and Sildenafil Options

Understanding Viagra vs Sildenafil: Same Medicine, Different Options

The key difference between Viagra and sildenafil lies in branding rather than effectiveness. Viagra, manufactured by Pfizer, contains sildenafil citrate as its active ingredient. Generic sildenafil contains the identical active ingredient but typically costs considerably less. Both work as PDE5 inhibitors, potentially increasing blood flow to the penis when sexual arousal occurs.

How Sildenafil-Based Treatments Work

Sildenafil works by blocking the phosphodiesterase type 5 (PDE5) enzyme, which may help improve blood circulation during sexual stimulation. The medication typically begins working within 30-60 minutes of taking and effects may last 4-6 hours. It's important to understand that sildenafil doesn't cause automatic erections - sexual stimulation remains necessary for the medication to be effective.

Available Dosage Options

Both Viagra and generic sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. Most patients start with 50mg, which can be adjusted to 25mg if side effects occur, or increased to 100mg if the initial dose proves insufficient. The maximum safe dosage is one tablet per 24-hour period, taken approximately 30-60 minutes before anticipated sexual activity.

Cost Considerations: Branded vs Generic

Generic sildenafil offers significant cost savings compared to branded Viagra whilst providing the same active ingredient and potential effectiveness. Many patients find generic sildenafil provides excellent value for money. At EverydayMeds, you can compare both options during checkout and select the choice that best suits your budget and preferences.

Eligibility and Safety Considerations

Both Viagra and sildenafil require prescription following consultation with a UK-licensed prescriber. The clinical assessment evaluates your cardiovascular health, current medications, and medical history to determine suitability. These medications are not suitable for men taking nitrate medications, those with severe heart conditions, or recent stroke/heart attack history. Our online consultation process ensures appropriate prescribing and identifies any potential contraindications.

Getting Started with EverydayMeds

Our streamlined process begins with completing a confidential medical questionnaire reviewed by UK-licensed prescribers. If suitable, you can choose between branded Viagra or generic sildenafil at checkout, with discrete delivery to your preferred address. Our clinical team remains available for ongoing support and dosage adjustments as needed.

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.
