Understanding Viagra: How ED Treatment Works
What is Viagra and How Does it Work?
Viagra contains the active ingredient sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor originally developed by Pfizer. When sexually aroused, the medication works by blocking the PDE5 enzyme, which increases blood flow to the penis. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
The medication typically begins working within 30-60 minutes of taking it, with effects lasting approximately 4-6 hours. This timeframe doesn't mean an erection will last for hours, but rather that the medication remains active in your system, allowing for normal erectile response during this period.
Viagra vs Sildenafil: Understanding Your Options
At EverydayMeds, we offer both branded Viagra and generic sildenafil, giving patients choice in their treatment. Both medications contain identical active ingredients and work in exactly the same way. The primary difference lies in cost - generic sildenafil typically offers significant savings whilst providing the same clinical effectiveness as the branded version.
Both options are available in 25mg, 50mg, and 100mg strengths. Most patients start with a 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and any side effects experienced. The maximum recommended dose is one tablet per 24-hour period.
Who Can Take Viagra or Sildenafil?
Viagra and sildenafil are prescription-only medicines suitable for adult men experiencing erectile dysfunction. Before prescribing, our UK-licensed clinicians conduct a comprehensive assessment covering medical history, current medications, and cardiovascular health. This ensures the treatment is both safe and appropriate for each individual patient.
The medication is not suitable for everyone. Men taking nitrate medications (such as GTN spray for angina), those with severe heart conditions, recent heart attack or stroke (within six months), severe liver problems, or very low blood pressure should not use these treatments. Additionally, certain medications can interact dangerously with sildenafil, making the clinical assessment crucial for patient safety.
What to Expect: Timing and Effectiveness
For optimal effectiveness, take your prescribed dose approximately 30-60 minutes before anticipated sexual activity. The medication works best on an empty stomach, as fatty meals can delay absorption and reduce effectiveness. Alcohol should be limited as it may reduce the medication's effectiveness and increase the risk of side effects.
Most men find significant improvement in their ability to achieve and maintain erections suitable for sexual activity. However, individual responses vary, and it may take several attempts to determine the most effective dose. Common mild side effects include headaches, facial flushing, indigestion, and nasal congestion, which typically resolve as the medication leaves your system.
Safety Considerations and When to Seek Help
Whilst generally well-tolerated, it's important to be aware of when to seek immediate medical attention. If you experience an erection lasting more than four hours (priapism), sudden vision or hearing loss, or chest pain during sexual activity, seek emergency medical help immediately.
Our clinical team provides ongoing support throughout your treatment journey. Regular reviews help ensure the medication continues to be appropriate and effective, with dosage adjustments made as needed based on your response and any changes in your health status.
