Understanding Viagra's Mechanism of Action
How Viagra Works in Your Body
Viagra contains sildenafil citrate, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. When you become sexually aroused, your body naturally produces nitric oxide, which helps relax the smooth muscles in your penis and allows blood vessels to widen. Viagra works by blocking the PDE5 enzyme that normally breaks down this process, helping to maintain increased blood flow to the penis.
Timeline and Effectiveness
Viagra typically becomes effective within 30-60 minutes of taking the tablet. The medication can remain active in your system for 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Sexual stimulation is still required for Viagra to work - it won't cause an automatic erection. Taking Viagra with a large or fatty meal may delay how quickly it starts working.
Available Treatment Options
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient (sildenafil citrate) and work identically in your body. The main difference is cost, with generic sildenafil typically being more affordable. Available strengths include 25mg, 50mg, and 100mg tablets, with 50mg being the standard starting dose for most men.
What to Expect When Taking Viagra
Most men find Viagra helps them achieve and maintain erections suitable for sexual activity. The medication may work better after taking it a few times, as your body adjusts to the treatment. Common factors that can affect how well Viagra works include alcohol consumption, stress levels, underlying health conditions, and other medications you may be taking. It's important to take only one dose within 24 hours and follow your prescriber's instructions carefully.
