Understanding Viagra's Effects on Sexual Performance
How Viagra Works and Its Impact on Duration
Viagra (sildenafil) works by increasing blood flow to the penis when sexually aroused, helping men achieve and maintain erections. While it doesn't directly extend how long you last during sexual activity, many men report improved confidence and reduced performance anxiety, which may indirectly help with duration. The medication takes effect within 30-60 minutes and can remain active for 4-6 hours, though this doesn't mean you'll have an erection for this entire period.
Common Side Effects: What to Expect
Understanding potential side effects helps you make informed decisions about ED treatment. The most frequently reported side effects of Viagra include headaches (occurring in approximately 16% of users), facial flushing (10-13%), and indigestion (7-17%). These effects are typically mild to moderate and often diminish as your body adjusts to the medication. Nasal congestion, dizziness, and visual disturbances (such as blue-tinted vision or increased light sensitivity) may also occur but are generally temporary.
Factors Affecting Side Effect Likelihood
Several factors influence whether you'll experience side effects with Viagra or generic sildenafil. Dosage plays a significant role - starting with the lowest effective dose (usually 50mg) can minimise unwanted effects. Your age, overall health, and other medications also impact side effect risk. Taking Viagra with alcohol or fatty meals may increase the likelihood of side effects like dizziness or flushing. At EverydayMeds, our clinical assessment helps determine the most appropriate starting dose for your individual circumstances.
Managing and Minimising Side Effects
Most Viagra side effects can be managed effectively with simple strategies. For headaches, staying well-hydrated and taking paracetamol (if suitable) may help. Facial flushing often resolves naturally within 1-2 hours. If you experience indigestion, taking the medication on an empty stomach or avoiding large, fatty meals beforehand may reduce this effect. Never take Viagra with nitrate medications (such as GTN spray) as this can cause dangerous blood pressure drops.
When to Seek Medical Advice
While most side effects are manageable, certain symptoms require immediate medical attention. Contact emergency services if you experience chest pain, sudden vision loss, or an erection lasting more than 4 hours (priapism). Sudden hearing loss, severe dizziness, or allergic reactions (rash, difficulty breathing, swelling) also warrant urgent medical care. For less serious but persistent side effects, consult your prescriber about adjusting your dose or considering alternative treatments.
Viagra vs Sildenafil: Side Effect Profiles
Both branded Viagra and generic sildenafil contain the same active ingredient and have identical side effect profiles. The choice between them often comes down to personal preference and cost considerations. Generic sildenafil offers the same effectiveness and safety profile as Viagra at a lower price point. EverydayMeds provides both options during checkout, allowing you to select based on your preferences after consultation with our UK-licensed prescribers.
