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 Generic Sildenafil Options

What's the Difference Between Viagra and Generic Sildenafil?

The fundamental difference between tablet Viagra and generic sildenafil lies in branding rather than medical effectiveness. Viagra is Pfizer's branded version of sildenafil citrate, whilst generic sildenafil contains the exact same active ingredient manufactured by other licensed pharmaceutical companies. Both work as PDE5 inhibitors, increasing blood flow to the penis when sexually aroused, typically taking effect within 30-60 minutes and lasting 4-6 hours.

Effectiveness and Clinical Results

Clinical studies consistently demonstrate that generic sildenafil delivers identical results to branded Viagra tablets. Both formulations must meet the same strict regulatory standards set by the MHRA (Medicines and Healthcare products Regulatory Agency). The bioavailability, onset time, and duration of action remain consistent between branded and generic versions. Whether you choose Viagra or sildenafil, you can expect the same level of effectiveness for treating erectile dysfunction.

Cost Considerations and Value

Generic sildenafil typically costs significantly less than branded Viagra tablets whilst providing identical therapeutic benefits. This price difference exists because generic manufacturers don't bear the research and development costs associated with bringing a new medication to market. For many patients, choosing generic sildenafil represents excellent value without compromising on quality or results. EverydayMeds offers transparent pricing for both options, allowing you to make an informed decision based on your budget and preferences.

Safety and Quality Standards

Both Viagra and generic sildenafil undergo rigorous quality testing and must meet identical safety standards. UK-licensed generic manufacturers must demonstrate bioequivalence to the original branded product through comprehensive testing. This means the medication is absorbed and works in your body at the same rate and to the same extent as branded Viagra. All sildenafil products available through EverydayMeds are sourced from licensed UK pharmacies and meet MHRA quality requirements.

Choosing Between Branded and Generic Options

Your choice between tablet Viagra and generic sildenafil often comes down to personal preference and budget considerations. Some patients prefer the reassurance of a well-known brand name, whilst others prioritise cost-effectiveness without compromising results. During your consultation with our UK-licensed prescribers, we'll discuss both options and help you make the choice that best suits your needs. Both formulations require the same clinical assessment to ensure suitability, considering your medical history, current medications, and cardiovascular health.

Dosing and Administration

Whether you choose Viagra or generic sildenafil, the dosing guidelines remain identical. Most patients start with 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability. Take one tablet 30-60 minutes before sexual activity, with a maximum of one dose per 24-hour period. Fatty meals may delay onset, so consider timing your dose accordingly. Both formulations require sexual stimulation to work effectively and don't cause automatic erections.

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.
