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 contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis when you're sexually aroused. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required. The medication works by blocking the enzyme phosphodiesterase type 5, which allows blood vessels to relax and improve circulation to erectile tissue.
Most men find that Viagra begins working within 30-60 minutes of taking the tablet. However, some may notice effects as early as 15-20 minutes, whilst others might need up to 90 minutes. The effects typically last between 4-6 hours, providing a suitable window for sexual activity. This doesn't mean you'll have an erection for this entire period - rather, you'll be able to achieve erections more easily when aroused.
Several factors can influence how quickly Viagra becomes effective. Taking it on an empty stomach generally produces faster results, as fatty meals can delay absorption by up to an hour. Alcohol consumption may also slow the onset and reduce effectiveness. Your age, overall health, and metabolism can affect timing too. Men with diabetes or cardiovascular conditions might experience slightly delayed effects.
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg proves insufficient. Remember, only one dose should be taken within 24 hours. EverydayMeds offers both branded Viagra and generic sildenafil in these strengths, allowing you to choose based on preference and budget.
To help Viagra work optimally, take it on an empty stomach when possible. Avoid excessive alcohol consumption, which can impair both the medication's effectiveness and your natural arousal response. Maintain realistic expectations - whilst Viagra significantly improves erectile function for most men, it works best when combined with appropriate sexual stimulation and a relaxed mindset.
If Viagra consistently takes longer than 90 minutes to work, or seems less effective over time, consult your healthcare provider. They may need to adjust your dosage or explore alternative treatments. Never exceed the recommended dose in an attempt to speed up effects, as this increases the risk of serious side effects including dangerous drops in blood pressure.
