Viagra Duration and Eligibility Requirements
How Long Does Viagra Last?
Viagra typically remains effective in your system for 4-6 hours after taking a dose. It's important to understand that this timeframe refers to the window during which the medication can help you achieve an erection with sexual stimulation - it does not mean you'll maintain an erection for the entire duration. The medication begins working within 30-60 minutes of taking it, with peak effectiveness usually occurring 1-2 hours after ingestion.
Several factors can influence how long Viagra lasts in your system, including your age, overall health, metabolism, and whether you've consumed food or alcohol. Fatty meals may delay the onset of action, while alcohol can reduce the medication's effectiveness. The 4-6 hour window represents the period during which you may be able to achieve and maintain an erection suitable for sexual activity when sexually aroused.
Who Can Take Viagra?
Viagra is suitable for adult men aged 18 and over who experience erectile dysfunction. However, not everyone is eligible to take this medication safely. At EverydayMeds, our UK-licensed prescribers conduct thorough clinical assessments to determine suitability for each patient. This assessment evaluates your medical history, current medications, cardiovascular health, and any underlying conditions that might affect your ability to take Viagra safely.
The medication works by increasing blood flow to the penis during sexual arousal, making it easier to achieve and maintain an erection. It's a prescription-only medicine in the UK, meaning you must have a valid prescription following consultation with a qualified healthcare professional. Our online consultation process ensures you receive appropriate medical oversight whilst maintaining privacy and convenience.
Medical Conditions and Contraindications
Certain medical conditions may prevent you from taking Viagra safely. Men with severe heart disease, recent heart attacks or strokes (within the past six months), severe liver problems, or very low blood pressure may not be suitable candidates for this medication. Additionally, if you're taking nitrate medications for chest pain (such as GTN spray or isosorbide tablets), you absolutely cannot take Viagra due to dangerous interactions that can cause life-threatening drops in blood pressure.
Other conditions requiring careful consideration include diabetes, high blood pressure, and certain eye conditions. During your consultation, it's crucial to provide complete and accurate information about your medical history and current medications to ensure Viagra is safe for you.
Branded Viagra vs Generic Sildenafil
At EverydayMeds, we offer both branded Viagra (manufactured by Pfizer) and generic sildenafil options. Both contain the same active ingredient - sildenafil citrate - and work in exactly the same way. The choice between branded and generic versions often comes down to personal preference and cost considerations, as generic sildenafil typically costs less whilst providing identical effectiveness.
Whether you choose branded Viagra or generic sildenafil, the duration of action remains the same at 4-6 hours. Both are available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose. Your prescriber may adjust the dose based on your response and any side effects experienced.
