Viagra, or sildenafil, directly addresses erectile dysfunction (ED) by increasing blood flow to the penis. This happens because Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5), allowing nitric oxide to work more effectively. Nitric oxide relaxes the muscles in the blood vessels, leading to improved blood flow.
Understanding How Viagra Works
The process is straightforward: sexual stimulation triggers the release of nitric oxide. Viagra enhances this process, resulting in a stronger erection. The effect is temporary, lasting for several hours.
- Viagra isn’t a stimulant; it facilitates a natural response. It requires sexual stimulation to work; it doesn’t cause spontaneous erections. Results vary between individuals, depending on factors like overall health and the cause of ED.
Choosing the Right Dosage
Your doctor will determine the appropriate dosage, typically starting with 50mg. Dosages can be adjusted based on individual responses and potential side effects. Common side effects include headaches, flushing, and nasal congestion. Always follow your doctor’s instructions.
Discuss your medical history with your doctor before starting Viagra. Report any side effects to your doctor immediately. Avoid combining Viagra with nitrates or certain other medications without consulting your doctor.
Beyond Viagra: Addressing the Root Cause
While Viagra provides effective treatment for ED symptoms, identifying and addressing the underlying cause is crucial for long-term management. Underlying conditions like diabetes, heart disease, or hormonal imbalances should be addressed by your doctor. Lifestyle changes like regular exercise, a healthy diet, and stress management can also contribute to improved erectile function.
