How Viagra Works and What to Expect
How Viagra Works in Your Body
Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, your body naturally releases nitric oxide, which increases blood flow to the penis. Viagra works by blocking the PDE5 enzyme that can reduce this blood flow, helping you achieve and maintain an erection suitable for sexual activity.
What Effects You Can Expect
Viagra typically begins working within 30-60 minutes of taking it on an empty stomach. The medication can remain effective for up to 4-6 hours, though this doesn't mean you'll have an erection for this entire time. Sexual stimulation is still required for the medication to work effectively. Many men find the 50mg starting dose effective, though your prescriber may recommend adjusting to 25mg or 100mg based on your response and any side effects experienced.
Branded Viagra vs Generic Sildenafil
EverydayMeds offers both Pfizer's branded Viagra and generic sildenafil options. 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 whilst providing the same therapeutic effects. You can choose between branded or generic options during checkout after completing your clinical assessment.
Common Side Effects and What to Expect
Most men tolerate Viagra well, though some may experience mild side effects such as headache, facial flushing, indigestion, or nasal congestion. These effects are usually temporary and tend to decrease as your body adjusts to the medication. Rarely, some men may experience changes in vision or prolonged erections lasting more than 4 hours, which require immediate medical attention.
