Understanding How Viagra and Sildenafil Work
Identical Active Ingredient, Different Branding
The fundamental difference between Viagra and sildenafil lies in branding rather than medical effectiveness. Viagra is the original branded medication manufactured by Pfizer, whilst sildenafil is the generic equivalent containing exactly the same active ingredient - sildenafil citrate. Both work as PDE5 inhibitors, blocking the phosphodiesterase type 5 enzyme to increase blood flow to the penis when sexually stimulated.
Timing and Effectiveness Comparison
When asking how long Viagra takes to work compared to sildenafil, both medications typically begin working within 30-60 minutes of taking the tablet. The onset time can be influenced by factors such as food consumption, particularly fatty meals which may delay absorption. Neither medication causes automatic erections - sexual stimulation is still required for both to be effective.
The effects of both Viagra and sildenafil can last 4-6 hours, though this doesn't mean an erection will persist for this duration. Rather, it indicates the window during which the medication may help achieve erections when sexually aroused.
Cost Considerations and Value
One of the most significant differences between Viagra and sildenafil is cost. Generic sildenafil is typically considerably less expensive than branded Viagra, making it an attractive option for men seeking the same therapeutic benefits at a lower price point. The active ingredient, dosage strengths (25mg, 50mg, 100mg), and clinical effectiveness remain identical between both options.
Choosing Between Viagra and Sildenafil
At EverydayMeds, we understand that treatment preferences vary between individuals. Some patients prefer the reassurance of the original branded medication, whilst others prioritise the cost savings offered by generic sildenafil. During our online consultation process, our UK-licensed prescribers will assess your suitability for either option and you can choose your preferred version at checkout.
Safety Profile and Contraindications
Both Viagra and sildenafil share identical safety profiles and contraindications. Neither should be taken by men using nitrate medications for heart conditions, those with severe cardiovascular disease, or recent stroke or heart attack survivors. The maximum recommended dose is one tablet per 24-hour period, regardless of which version you choose.
Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These effects are generally mild and temporary. More serious side effects, whilst rare, require immediate medical attention and include prolonged erections lasting over four hours or sudden vision changes.
Clinical Assessment and Prescription Process
Both medications require prescription following assessment by a qualified healthcare professional. Our online consultation process evaluates your medical history, current medications, and cardiovascular health to ensure either Viagra or sildenafil is safe and appropriate for your circumstances. This assessment is identical regardless of which version you ultimately choose to purchase.
