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.
Most men experience minimal side effects when taking sildenafil, whether choosing the generic version or branded Viagra. Common side effects typically occur in the first few hours after taking the medication and usually resolve without treatment. These may include headache, facial flushing, nasal congestion, and mild digestive upset. Studies indicate these effects occur in approximately 10-15% of users and tend to become less noticeable with continued use.
While rare, certain serious side effects require emergency medical care. Priapism, an erection lasting more than four hours, affects less than 1% of users but requires immediate treatment to prevent permanent damage. Sudden vision loss in one or both eyes, though extremely rare, has been reported and necessitates stopping sildenafil immediately. Similarly, sudden hearing loss or ringing in the ears requires urgent medical evaluation. Chest pain during sexual activity should prompt immediate cessation of activity and medical consultation.
Sildenafil can cause a temporary drop in blood pressure, which is usually well-tolerated in healthy men. However, this effect becomes dangerous when combined with nitrate medications used for heart conditions. The combination can cause a life-threatening drop in blood pressure. Men with heart disease, recent heart attacks, or stroke within six months require careful medical evaluation before starting treatment. EverydayMeds' clinical assessment specifically evaluates cardiovascular risk factors.
Several medications interact dangerously with sildenafil. Nitrates, including GTN spray and isosorbide, are absolutely contraindicated. Alpha-blockers used for blood pressure or prostate problems may cause excessive blood pressure drops when combined with sildenafil. Some antibiotics, antifungals, and HIV medications can increase sildenafil levels in the blood, potentially intensifying side effects. Always disclose all medications, including over-the-counter supplements, during your consultation.
Both generic sildenafil and Viagra contain identical active ingredients and carry the same side effect profile. The choice often comes down to personal preference and cost considerations. Generic sildenafil typically offers significant cost savings whilst maintaining the same effectiveness and safety profile as Viagra. EverydayMeds provides both options, allowing patients to choose based on their individual preferences and budget during the checkout process.
Several strategies can help minimise potential side effects. Taking sildenafil on an empty stomach or after a light meal can improve absorption and reduce digestive upset. Avoiding excessive alcohol consumption reduces the risk of dizziness and blood pressure drops. Starting with the lowest effective dose, typically 50mg, allows assessment of individual tolerance. Never exceed one dose within 24 hours, regardless of effectiveness. If side effects persist or worsen, consult with your prescriber about dose adjustment or alternative treatments.
