When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
Most men find that Viagra begins working within 30-60 minutes of taking the tablet. The medication contains sildenafil citrate, which works by blocking the PDE5 enzyme to increase blood flow to the penis during sexual arousal. However, timing can vary based on individual factors including age, overall health, and whether you've eaten recently.
Several factors may influence how quickly Viagra takes effect. Taking the medication on an empty stomach typically results in faster absorption, whilst heavy or fatty meals can delay onset by up to an hour. Alcohol consumption may also slow absorption and reduce effectiveness. Your metabolism, age, and underlying health conditions can all impact timing.
Generic sildenafil contains the exact same active ingredient as branded Viagra but typically costs significantly less. Both medications work identically, taking the same 30-60 minutes to become effective. The only differences are the manufacturer, appearance, and price. Many patients choose generic sildenafil for the cost savings whilst maintaining the same clinical effectiveness.
Viagra's effects typically last 4-6 hours, though this doesn't mean you'll have an erection for this entire period. The medication simply makes it easier to achieve and maintain erections when sexually aroused during this timeframe. After about 4 hours, the medication begins clearing from your system, and effectiveness gradually decreases.
If Viagra doesn't work optimally for you, several alternatives may be worth discussing with a prescriber. Cialis (tadalafil) offers longer-lasting effects of up to 36 hours but may take similar time to start working. Levitra (vardenafil) works similarly to Viagra but may be less affected by food. Daily low-dose tadalafil provides continuous treatment rather than on-demand dosing.
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken about an hour before sexual activity. If this proves insufficient, your prescriber might recommend increasing to 100mg. Conversely, if you experience side effects, reducing to 25mg may help whilst maintaining effectiveness. Only one dose should be taken per 24-hour period.
