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 the Differences Between Viagra and Sildenafil

What's the Difference Between Viagra and Sildenafil?

The fundamental truth is that Viagra and sildenafil are essentially the same medication. Viagra is simply the brand name for sildenafil citrate, originally developed by Pfizer. Generic sildenafil contains the identical active ingredient in the same concentrations, meaning both work in exactly the same way to treat erectile dysfunction.

Both medications are PDE5 inhibitors that work by increasing blood flow to the penis when you're sexually aroused. They typically take 30-60 minutes to work and can remain effective for 4-6 hours, though this doesn't mean you'll have an erection for this entire period.

Cost Considerations: Why Sildenafil May Be More Economical

One of the most significant advantages of choosing generic sildenafil is the substantial cost savings. Since generic manufacturers don't need to recoup research and development costs, sildenafil is typically available at a fraction of the price of branded Viagra whilst offering identical therapeutic benefits.

For men requiring long-term treatment, these savings can be considerable over time. At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout, allowing you to select the option that best suits your budget and preferences.

Availability and Dosage Options

Viagra Connect (50mg sildenafil) became available over-the-counter in UK pharmacies in 2018, making it more accessible than prescription versions. However, this over-the-counter option is limited to the 50mg strength and requires a pharmacy consultation.

Prescription sildenafil and Viagra are available in 25mg, 50mg, and 100mg strengths, offering more flexibility for dosage adjustment. Your prescriber may recommend starting with 50mg and adjusting based on effectiveness and any side effects you might experience.

Making Your Choice: Branded vs Generic

When deciding between Viagra and sildenafil, consider that both options offer identical therapeutic benefits. Your choice may come down to personal preference, budget considerations, and brand familiarity. Some men prefer the reassurance of a well-known brand name, whilst others prioritise the cost-effectiveness of generic alternatives.

Both medications have the same potential side effects, including headaches, flushing, indigestion, and nasal congestion. Neither is suitable for men taking nitrate medications or those with certain cardiovascular conditions.

Getting Treatment Through EverydayMeds

EverydayMeds offers both branded Viagra and generic sildenafil following a comprehensive online consultation with UK-licensed prescribers. This consultation ensures the medication is appropriate for your individual circumstances and medical history.

The clinical assessment covers your cardiovascular health, current medications, and any contraindications. Once approved, you can choose your preferred option at checkout, whether that's the branded version or the more economical generic alternative.

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.
