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 works by increasing blood flow to the penis during sexual arousal. It doesn't cause automatic erections - sexual stimulation is still required. The medication typically begins working within 30-60 minutes and effects can last 4-6 hours. This doesn't mean you'll have an erection for hours, but rather that the medication remains active in your system during this timeframe.
Viagra has been extensively studied since its approval in 1998. Clinical trials involving thousands of men demonstrate that when prescribed appropriately, Viagra is generally well-tolerated. Most first-time users experience either no side effects or mild, temporary ones. The most common side effects include headache, facial flushing, indigestion, and nasal congestion. These typically resolve within a few hours as the medication leaves your system.
Certain individuals should not use Viagra due to safety concerns. This includes men taking nitrate medications (such as GTN spray for chest pain), those with severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure. Men taking riociguat for pulmonary hypertension must also avoid Viagra due to dangerous interactions. This is why a thorough medical assessment is essential before starting treatment.
First-time users typically start with 50mg of sildenafil, taken 30-60 minutes before sexual activity. Depending on effectiveness and any side effects experienced, this may be adjusted to 25mg (if side effects occur) or increased to 100mg (if 50mg proves insufficient). Never exceed one dose in 24 hours. Taking Viagra with fatty meals may delay its effectiveness, so consider timing your dose accordingly.
Viagra can interact dangerously with certain medications. The most serious interaction occurs with nitrates, used for chest pain, which can cause a severe drop in blood pressure. Alpha-blockers for prostate problems may also interact. Always inform your prescriber about all medications you're taking, including over-the-counter medicines and supplements. This information is crucial for determining whether Viagra is safe for you.
Pay attention to how your body responds during your first few uses of Viagra. Contact your healthcare provider if you experience severe side effects, prolonged erections lasting more than 4 hours, sudden vision or hearing changes, or chest pain. Most men find Viagra works well with minimal side effects, but monitoring your response helps ensure continued safe use.
Both branded Viagra and generic sildenafil contain the same active ingredient and have identical safety profiles. The choice often comes down to personal preference and cost considerations. Generic sildenafil offers the same effectiveness at a lower price point. EverydayMeds provides both options following your online consultation, allowing you to choose based on your individual needs and budget.
