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.
Many patients ask about treatment duration, but it's important to understand that when we say Viagra lasts 4-6 hours, this doesn't mean you'll have an erection for that entire time. The medication creates a window where achieving an erection becomes easier when sexually aroused, but the erection itself typically lasts only as long as sexual stimulation continues.
Both Viagra and its generic equivalent sildenafil contain the same active ingredient and work identically. They typically begin working within 30-60 minutes and remain effective for 4-6 hours. The peak effectiveness usually occurs 1-2 hours after taking the tablet. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout, with sildenafil offering significant cost savings.
Whilst sildenafil offers reliable 4-6 hour effectiveness, some patients prefer longer-acting alternatives like tadalafil, which can remain effective for up to 36 hours. This extended window may suit those who prefer more spontaneous intimacy without timing tablet intake. However, shorter-acting treatments like sildenafil may be preferable for those who want more control over when the medication is active.
Several factors can influence how long ED treatments work effectively. Age, overall health, other medications, and food intake can all impact duration. Fatty meals may delay onset but don't significantly affect overall duration. Alcohol consumption should be limited as it can reduce effectiveness and increase the risk of side effects.
The best treatment duration depends on your lifestyle and preferences. Some couples prefer the predictability of shorter-acting treatments, whilst others value the flexibility of longer-acting options. Our UK-licensed prescribers at EverydayMeds assess your individual circumstances during consultation to recommend the most suitable treatment duration and strength.
Regardless of duration, all ED treatments require sexual stimulation to work effectively. They don't cause automatic erections and shouldn't be taken more than once in 24 hours. Both branded and generic options undergo the same rigorous safety testing and are equally effective when prescribed appropriately following clinical assessment.
It's one of the most common conditions we treat, and one of the most treatable.
