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 has been extensively studied since its approval in 1998, with millions of men using it safely worldwide. The active ingredient, sildenafil citrate, works by inhibiting the PDE5 enzyme to increase blood flow to the penis during sexual arousal. Clinical trials demonstrate that Viagra is generally well-tolerated when prescribed appropriately following proper medical assessment.
Both medications share similar side effect profiles, though the frequency may differ slightly. Viagra commonly causes headaches, facial flushing, nasal congestion, and indigestion in some users. These effects are typically mild and temporary. Tadalafil may cause similar symptoms but some users report fewer headaches compared to sildenafil. Back pain and muscle aches occur more frequently with Tadalafil, affecting approximately 6% of users.
Viagra typically remains effective for 4-6 hours after taking, requiring timing around sexual activity. You should take it 30-60 minutes before intimacy, and fatty meals may delay its onset. Tadalafil offers greater flexibility with its 36-hour duration of action, earning it the nickname "the weekend pill". This extended window may suit men who prefer spontaneity over planned timing.
Both medications have similar cardiovascular safety profiles. Neither should be combined with nitrate medications (such as GTN spray) due to dangerous blood pressure interactions. Men with severe heart conditions, recent heart attacks, or uncontrolled blood pressure require careful medical evaluation before using either treatment. Studies suggest both sildenafil and Tadalafil may actually provide some cardiovascular benefits in certain patients.
Viagra and Tadalafil share most contraindications and drug interactions. Both are unsuitable for men taking nitrates, riociguat, or certain blood pressure medications. Alpha-blockers may interact with both drugs, potentially causing dizziness or low blood pressure. Your prescriber will review all current medications during consultation to ensure safe prescribing.
At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout. Generic sildenafil contains identical active ingredients to Viagra but costs significantly less. The same cost comparison applies to Tadalafil, where generic versions offer substantial savings. Many men find generic alternatives provide identical effectiveness at a fraction of branded prices.
Your lifestyle and preferences often determine the most suitable choice. Viagra may be preferred if you have predictable timing for sexual activity and want a shorter duration of action. Tadalafil might suit men who value spontaneity and don't want to plan around medication timing. Some men try both options (not simultaneously) to determine personal preference. Your prescriber can help evaluate which treatment aligns best with your needs and medical history.
