Sildenafil citrate, the active ingredient in Viagra, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, enabling men to achieve and maintain an erection.
How Sildenafil Citrate Works
Sildenafil inhibits a specific enzyme, phosphodiesterase-5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, sildenafil allows for increased blood vessel dilation, leading to improved erectile function.
- This process requires sexual stimulation to initiate. Sildenafil doesn’t directly cause an erection; it facilitates the natural erectile response.
Beyond Erectile Dysfunction: Other Uses
Beyond ED, sildenafil also finds application in treating pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries of the lungs. Here, it improves blood flow and reduces strain on the heart.
Important Considerations
Consult a doctor before using sildenafil, especially if you have heart problems, low blood pressure, or take other medications. Common side effects include headaches, flushing, and nasal congestion. Severe side effects are rare but require immediate medical attention. Sildenafil interacts with certain medications; inform your doctor about all your current prescriptions and supplements. Dosage varies depending on the condition being treated and individual factors. Always follow your doctor’s instructions.
Sildenafil and Dosage
Your doctor will determine the appropriate dosage. Typical starting doses vary, and adjustments may be necessary based on response and tolerance.
Seeking Professional Advice
Always consult a healthcare professional before starting any new medication, including sildenafil. They can assess your individual needs and provide tailored guidance.
