How Viagra Works and What Effects to Expect
How Viagra Affects Your Body
Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you take Viagra, it blocks the phosphodiesterase type 5 enzyme, which normally breaks down a substance called cGMP. By preventing this breakdown, Viagra allows blood vessels in the penis to relax and widen during sexual arousal, increasing blood flow and helping achieve an erection.
Timeline of Effects
Most men notice Viagra's effects within 30-60 minutes of taking the tablet. The medication reaches peak concentration in your bloodstream approximately one hour after taking it. However, the timing can vary based on factors such as whether you've eaten recently, your age, and your overall health. Fatty meals may delay the onset of effects, so it's often recommended to take Viagra on an empty stomach or after a light meal.
Duration and What to Expect
Viagra's effects typically last between 4-6 hours, though this doesn't mean you'll have an erection for this entire time. Instead, it means you may find it easier to achieve and maintain erections during this window when sexually aroused. The medication remains in your system during this period, but you still need sexual stimulation for it to work effectively.
Common Effects You May Experience
Beyond its primary effect on erectile function, Viagra may cause some side effects. Common mild effects include headaches, facial flushing, indigestion, and nasal congestion. These typically resolve as your body adjusts to the medication. Some men also report feeling more confident about their sexual performance, which can have positive psychological effects.
Dosage and Effectiveness
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, which can be adjusted based on effectiveness and tolerability. You should only take one dose within a 24-hour period. At EverydayMeds, patients can choose between branded Viagra or sildenafil (the generic version), which contains the same active ingredient at a lower cost.
Important Considerations
Viagra won't work without sexual arousal - it enhances your natural response rather than creating an artificial one. It's also crucial to understand that Viagra doesn't address underlying psychological causes of ED or increase sexual desire. The medication is most effective when used as part of a comprehensive approach to sexual health that may include lifestyle changes and addressing any underlying health conditions.
