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.
Viagra should be taken approximately 30-60 minutes before you plan to engage in sexual activity. This timing allows the medication to be absorbed into your bloodstream and begin working effectively. The active ingredient sildenafil citrate requires time to inhibit the PDE5 enzyme and increase blood flow to the penis when sexual arousal occurs.
What you eat before taking Viagra can significantly impact its effectiveness. Heavy or fatty meals can delay the medication's absorption, potentially extending the time before it begins working. For optimal results, consider taking Viagra on an empty stomach or after a light meal. If you've consumed a large meal, you may need to wait longer than the typical 30-60 minutes for the medication to take effect.
Viagra's effects typically last between 4-6 hours after taking the tablet. This doesn't mean you'll maintain an erection for this entire period - sexual stimulation is still required for the medication to work. The 4-6 hour window simply indicates how long the medication remains effective in your system, allowing for spontaneity during this timeframe.
Most patients start with a 50mg dose of Viagra, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability. Crucially, you should never take more than one dose within a 24-hour period, regardless of the strength. Taking multiple doses can increase the risk of serious side effects, particularly dangerous drops in blood pressure.
EverydayMeds offers both Viagra (the branded version) and Sildenafil (the generic alternative) at checkout following your consultation. Both contain the same active ingredient and work identically - the main difference is cost, with Sildenafil typically being more affordable. Your choice between branded and generic options won't affect the timing recommendations outlined above.
Several factors can affect Viagra's effectiveness and timing. Excessive alcohol consumption can impair the medication's ability to work and may delay its onset. Stress, anxiety, and certain medical conditions can also impact effectiveness. If you find Viagra isn't working as expected, consult with a healthcare professional rather than adjusting the timing or dosage yourself.
