Brand Viagra 100mg contains sildenafil citrate, a medication that treats erectile dysfunction (ED). It works by increasing blood flow to the penis, helping achieve and maintain an erection during sexual stimulation.
Understanding the Mechanism
Sildenafil inhibits a specific enzyme called phosphodiesterase-5 (PDE5). This enzyme breaks down a chemical called cyclic guanosine monophosphate (cGMP), which is crucial for penile erection. By blocking PDE5, sildenafil allows cGMP levels to rise, resulting in increased blood flow to the penis.
Factors Affecting Efficacy
- Dosage: 100mg is a common dose, but your doctor may adjust it based on your individual needs and response. Sexual Stimulation: Viagra doesn’t cause erections on its own; sexual stimulation is necessary. Health Conditions: Certain health conditions and medications can affect Viagra’s effectiveness. Discuss your complete medical history with your doctor. Diet and Lifestyle: Maintaining a healthy lifestyle, including diet and exercise, can contribute to overall sexual health.
Possible Side Effects
Common side effects include headache, flushing, nasal congestion, and indigestion. Less common, but more serious side effects, exist; seek immediate medical attention if you experience vision changes, chest pain, or prolonged erection.
Important Considerations
Consult your doctor: Always consult a healthcare professional before taking Viagra to determine if it’s appropriate for you and to discuss potential risks. Follow directions: Take Viagra exactly as prescribed by your doctor. Interactions: Inform your doctor about all medications you’re currently taking, as interactions can occur.
When to Seek Medical Attention
Contact your doctor immediately if you experience prolonged or painful erections (priapism), sudden vision loss, or hearing loss.
