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 vs Sildenafil: What's the Difference?

Active Ingredient and Effectiveness

Both branded Viagra and generic sildenafil contain sildenafil citrate as their active ingredient. This PDE5 inhibitor works by increasing blood flow to the penis when sexually aroused, helping men achieve and maintain erections suitable for sexual activity. The effectiveness is identical between branded and generic versions, as both must meet the same stringent regulatory standards set by the MHRA.

Cost Considerations

Generic sildenafil typically offers significant cost savings compared to branded Viagra. This makes it an attractive option for men seeking effective ED treatment whilst managing healthcare expenses. The lower cost doesn't reflect reduced quality - generic medications undergo rigorous testing to ensure bioequivalence with their branded counterparts.

Dosage Options and Flexibility

Both Viagra and sildenafil are available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescribing clinician may adjust the dose based on effectiveness and any side effects experienced. The maximum recommended dose is 100mg, and only one tablet should be taken within 24 hours.

Clinical Assessment Process

Whether choosing branded Viagra or generic sildenafil, a clinical assessment is required. Our UK-licensed prescribers evaluate your medical history, current medications, and cardiovascular health to ensure safe prescribing. This assessment helps identify any contraindications, such as concurrent nitrate medication use or recent cardiovascular events.

Onset and Duration

Both formulations typically begin working within 30-60 minutes of administration. The effects may last up to 4-6 hours, though this doesn't mean an erection will persist throughout this period. Sexual stimulation remains necessary for the medication to be effective. Taking the tablet with a heavy or fatty meal may delay onset of action.

Choosing Between Branded and Generic

The choice between Viagra and sildenafil often comes down to personal preference and budget considerations. Some men prefer the familiarity of the branded product, whilst others opt for the cost-effective generic alternative. At EverydayMeds, you can select your preferred option during the checkout process, ensuring you receive the formulation that best suits your needs.

Safety Considerations

Both medications carry the same contraindications and potential side effects. They should not be used by men taking nitrates for chest pain or those with severe cardiovascular disease. Common side effects may include headache, facial flushing, and nasal congestion. Serious side effects are rare but require immediate medical attention.

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.
