Viagra, or sildenafil citrate, helps men achieve and maintain an erection. It works by increasing blood flow to the penis.
How Viagra Works
Viagra blocks an enzyme called phosphodiesterase-5 (PDE5). This allows more nitric oxide to remain in the penis, resulting in improved blood flow. The increased blood flow facilitates erections in response to sexual stimulation.
Benefits Beyond Erection
Studies suggest potential benefits beyond erectile dysfunction. Some research indicates Viagra might help treat pulmonary hypertension, a condition affecting blood pressure in the lungs. Consult your doctor to discuss these possibilities. Remember to always follow your physician’s guidance.
Important Considerations
Viagra is a prescription medication. Before taking it, discuss your medical history, including any existing conditions or medications you are currently using, with your doctor. Common side effects include headaches, flushing, and nasal congestion. Severe side effects are rare but require immediate medical attention.
Dosage and Administration
Your doctor will determine the appropriate dosage based on your individual needs and health status. Generally, it’s taken as needed, about an hour before sexual activity. Never exceed the prescribed dosage.
