Understanding Your Sildenafil Treatment Choices

What is Sildenafil and How Does It Compare to Viagra?

Sildenafil citrate is a PDE5 inhibitor medication that helps treat erectile dysfunction by increasing blood flow to the penis during sexual arousal. The generic version contains exactly the same active ingredient as Viagra but typically costs significantly less. Both medications work identically - the main difference lies in branding and price. Many patients choose generic sildenafil for its cost-effectiveness, whilst others prefer the branded option. At EverydayMeds, you can select either generic sildenafil or Viagra during your order, giving you complete flexibility.

Available Dosages and How They Work

Sildenafil is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg proves insufficient. The medication works by blocking the PDE5 enzyme, which helps maintain increased blood flow when you're sexually aroused. It's important to note that sildenafil doesn't cause automatic erections - sexual stimulation is still required for it to be effective.

Clinical Assessment and Eligibility

Before prescribing sildenafil, a qualified healthcare professional must assess your suitability through a clinical consultation. This evaluation considers your medical history, current medications, and cardiovascular health. The assessment helps ensure sildenafil is safe and appropriate for your individual circumstances. Men taking certain medications, particularly nitrates for heart conditions, cannot safely use sildenafil due to potentially dangerous interactions that could cause severely low blood pressure.

Effectiveness and What to Expect

Clinical studies show that sildenafil helps approximately 70-80% of men with erectile dysfunction achieve erections sufficient for sexual activity. The medication typically begins working within 30-60 minutes of taking it, with peak effectiveness occurring around one hour after consumption. Effects may last up to 4-6 hours, though this doesn't mean you'll have an erection for this entire duration. Taking sildenafil with a large or fatty meal may delay its onset of action.

Cost Considerations and Value

Generic sildenafil offers substantial savings compared to branded Viagra whilst providing identical therapeutic benefits. The cost difference can be significant over time, making generic sildenafil an attractive option for many patients. Both formulations undergo the same rigorous quality standards and contain identical amounts of active ingredient. Your choice between generic sildenafil and Viagra often comes down to personal preference and budget considerations, as both are clinically equivalent in terms of safety and effectiveness.
