Clinical Evidence & Effectiveness Data
Proven Clinical Results
Viagra (sildenafil citrate) has demonstrated consistent effectiveness in numerous clinical trials since its introduction. Studies show that approximately 70-80% of men with erectile dysfunction experience significant improvement when taking Viagra. The medication works by blocking the PDE5 enzyme, increasing blood flow to the penis during sexual arousal.
Factors Affecting Success Rates
Effectiveness rates can vary depending on several factors. Men with diabetes may experience slightly lower success rates (around 60-70%), whilst those with psychological ED often see higher rates. Age also plays a role - younger men typically report better outcomes. The presence of cardiovascular disease, smoking, or other health conditions may influence how well the medication works.
Dosage and Optimisation
Most men start with a 50mg dose, which can be adjusted based on effectiveness and tolerability. Some may require 100mg for optimal results, whilst others find 25mg sufficient. It's important to take Viagra 30-60 minutes before sexual activity on an empty stomach for best results. Heavy or fatty meals can delay the onset of action.
Branded vs Generic Options
Generic sildenafil contains the same active ingredient as branded Viagra and demonstrates identical effectiveness rates in clinical studies. The main difference lies in cost - generic sildenafil typically costs significantly less whilst providing the same therapeutic benefits. EverydayMeds offers both options, allowing patients to choose based on preference and budget during the online consultation process.
What to Expect
When effective, Viagra helps achieve erections firm enough for penetration within 30-60 minutes of taking the tablet. Effects can last 4-6 hours, though this doesn't mean maintaining an erection for this duration. Sexual stimulation is still required for the medication to work. Most men notice improvement from the first dose, though some may need 2-3 attempts for optimal results.
When Viagra May Not Work
Approximately 20-30% of men don't respond adequately to Viagra. This could be due to severe vascular damage, very low testosterone levels, certain medications that interfere with effectiveness, or psychological factors requiring additional support. If Viagra isn't effective, alternative ED treatments may be more suitable.
Safety and Suitability Assessment
Before prescribing Viagra or sildenafil, UK healthcare providers conduct thorough assessments to ensure safety and suitability. This includes reviewing medical history, current medications, and cardiovascular health. Men taking nitrates or with certain heart conditions cannot safely use Viagra. EverydayMeds' online consultation process ensures appropriate clinical oversight whilst maintaining convenience and privacy.
