How Viagra and Sildenafil Work in Your Body
The Science Behind Sildenafil
Both Viagra and generic sildenafil work by blocking an enzyme called phosphodiesterase type 5 (PDE5). This action helps relax blood vessels in the penis, allowing increased blood flow when you become sexually aroused. It's important to understand that these medications don't cause automatic erections - sexual stimulation is still required for them to be effective.
Identical Active Ingredients, Different Packaging
The key point many patients don't realise is that Viagra and sildenafil contain exactly the same active ingredient. Viagra is simply the brand name created by Pfizer, whilst sildenafil is the generic version. Both undergo the same rigorous testing and meet identical quality standards set by the MHRA (Medicines and Healthcare products Regulatory Agency).
Timing and Duration of Effects
Whether you choose branded Viagra or generic sildenafil, the timing remains consistent. Both typically begin working within 30-60 minutes of taking the tablet. The effects can last up to 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Food, particularly fatty meals, may delay the onset of action for both formulations.
Dosage Options Available
EverydayMeds offers both Viagra and sildenafil in three strengths: 25mg, 50mg, and 100mg. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg depending on effectiveness and any side effects experienced. Your prescriber will recommend the most appropriate starting dose based on your medical history and current medications.
Cost Considerations
Generic sildenafil typically costs considerably less than branded Viagra, often representing savings of 70-80%. This makes sildenafil an attractive option for men seeking effective ED treatment whilst managing healthcare costs. Both versions require a prescription following consultation with a UK-licensed prescriber, ensuring you receive appropriate medical oversight regardless of your choice.
Safety Profile and Side Effects
Since both medications contain identical active ingredients, their side effect profiles are the same. Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These effects are usually mild and temporary. More serious side effects are rare but can include sudden vision or hearing loss, or prolonged erections lasting over four hours, which require immediate medical attention.
Who Cannot Take These Medications
Both Viagra and sildenafil have identical contraindications. Men taking nitrate medications (such as GTN spray), those with severe heart conditions, recent stroke or heart attack survivors, or men with severe liver problems should not use these treatments. This is why our online consultation process thoroughly reviews your medical history and current medications before prescribing.
Making Your Choice
When deciding between Viagra and sildenafil, consider that effectiveness remains identical. Your choice may depend on personal preference for branded medications versus cost considerations. Some men prefer the familiarity of the Viagra brand, whilst others appreciate the cost savings offered by generic sildenafil. At EverydayMeds, you can choose between both options during checkout following your approved consultation.
