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 (sildenafil citrate) works by blocking the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. However, this medication requires sexual stimulation to be effective - it doesn't create an automatic erection. The drug typically takes 30-60 minutes to work and can be influenced by various factors that may reduce its effectiveness.
Several factors can impact how well Viagra works. Taking the medication with a large or fatty meal can delay absorption and reduce effectiveness. Alcohol consumption, particularly in large amounts, can also interfere with the medication's action and worsen erectile function. Additionally, some men may need dosage adjustments - the standard 50mg starting dose might need to be increased to 100mg or decreased to 25mg depending on individual response.
Certain medications can interfere with Viagra's effectiveness or create dangerous interactions. Alpha-blockers used for prostate problems or high blood pressure can enhance Viagra's blood pressure-lowering effects. Some antidepressants, particularly SSRIs, may reduce sexual response even when taking ED medication. Always inform your prescriber about all medications you're taking to avoid potential interactions.
Cardiovascular conditions, diabetes, and hormonal imbalances can all impact how well ED medications work. Low testosterone levels, in particular, may reduce the effectiveness of Viagra and might require additional treatment. Severe anxiety or depression can also affect sexual function despite taking medication. If underlying conditions aren't properly managed, ED treatments may be less effective.
If Viagra isn't working effectively, several options may help. Your prescriber might adjust the dosage or suggest trying at different times relative to food and alcohol consumption. Alternative PDE5 inhibitors like tadalafil or vardenafil may work better for some men. At EverydayMeds, we offer both branded Viagra and generic sildenafil, giving you treatment options to discuss with our UK-licensed prescribers during your online consultation.
