How Viagra Works and What to Expect
How Does Viagra Work?
Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, your body naturally releases nitric oxide, which increases blood flow to the penis. The enzyme PDE5 can break down this process, making it difficult to achieve or maintain an erection. Viagra works by blocking PDE5, allowing increased blood flow to continue and helping you achieve an erection when sexually stimulated.
It's important to understand that Viagra doesn't cause automatic erections. Sexual arousal and stimulation are still required for the medication to be effective. The drug essentially enhances your body's natural response to sexual stimulation.
Viagra Effectiveness Rates
Clinical studies demonstrate that Viagra can be highly effective for treating erectile dysfunction. Research shows that approximately 70-85% of men experience improved erections when taking sildenafil. The effectiveness can vary based on several factors including the underlying cause of ED, overall health, age, and dosage used.
Men with ED caused by psychological factors often see higher success rates, while those with underlying health conditions like diabetes or cardiovascular disease may experience varying results. Your healthcare provider can help determine if Viagra is likely to be effective for your specific situation.
Timeline and Duration
Viagra typically begins working within 30-60 minutes of taking the tablet. For optimal results, it's recommended to take Viagra on an empty stomach, as fatty foods can delay absorption and reduce effectiveness. The effects can last for 4-6 hours, though this doesn't mean you'll have an erection for this entire period.
The medication works only when you're sexually aroused during this window. Many men find that taking Viagra about an hour before planned sexual activity provides the best results.
Dosage and Treatment Options
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted based on effectiveness and any side effects experienced. Your prescriber will determine the most appropriate starting dose based on your medical history and current medications.
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient and work identically, with sildenafil offering a more cost-effective option while maintaining the same clinical effectiveness.
Factors Affecting Effectiveness
Several factors can influence how well Viagra works for you. Alcohol consumption can reduce effectiveness and increase the risk of side effects. Certain medications, particularly nitrates used for chest pain, can interact dangerously with Viagra and must be avoided.
Underlying health conditions such as diabetes, high blood pressure, or heart disease may affect how well the medication works. Lifestyle factors including smoking, lack of exercise, and stress can also impact effectiveness. Discussing these factors with your healthcare provider helps ensure the best possible outcomes.
