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 is licensed for use in adult men aged 18 years and over who experience erectile dysfunction. There is no upper age limit for Viagra use, though older patients may require more careful medical assessment due to increased likelihood of cardiovascular conditions or other health issues that could affect treatment suitability. Men over 65 may be started on a lower dose of 25mg to assess tolerance before considering dose increases.
Before prescribing Viagra, healthcare providers must conduct a thorough clinical assessment to ensure safe use. This evaluation includes reviewing your medical history, current medications, and cardiovascular health status. The assessment helps identify any contraindications or potential drug interactions that could make Viagra treatment unsafe. Blood pressure measurements and heart health evaluation are particularly important, as Viagra can affect cardiovascular function.
Several medical conditions and circumstances make Viagra unsuitable. Men taking nitrate medications for chest pain (such as GTN spray or isosorbide tablets) must not use Viagra due to dangerous blood pressure interactions. Those with severe heart disease, recent heart attacks or strokes within six months, severe liver problems, or very low blood pressure are also excluded from treatment. Additionally, men with certain rare inherited eye conditions or allergies to sildenafil cannot take this medication.
Cardiovascular assessment is crucial when considering Viagra treatment, as sexual activity itself places demands on the heart. Men with stable heart conditions may still be candidates for Viagra, but those with unstable angina, uncontrolled high blood pressure, or recent cardiovascular events require specialist evaluation before treatment can be considered. Your prescriber will assess whether your heart is healthy enough for sexual activity and Viagra use.
Certain medications can interact dangerously with Viagra, making thorough medication review essential. Beyond nitrates, other problematic combinations include some blood pressure medications (alpha-blockers), HIV protease inhibitors, and antifungal medications, which can increase sildenafil levels in the blood. Some antibiotics and seizure medications may also affect how Viagra works in your body.
At EverydayMeds, eligible patients can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically, with generic options offering significant cost savings. The choice between branded and generic is purely personal preference, as both undergo the same rigorous safety and efficacy standards. Your prescriber can advise on the most suitable option based on your individual circumstances and treatment goals.
