Viagra, or sildenafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for firmer, easier-to-achieve erections.
It works by inhibiting an enzyme called phosphodiesterase-5 (PDE5), which regulates blood vessel dilation. By blocking PDE5, Viagra allows for more blood to flow into the penis during sexual stimulation.
Important considerations include taking Viagra only as prescribed by a doctor. Discuss potential side effects and drug interactions with your physician before use. Common side effects may include headache, flushing, and nasal congestion.
Viagra is not a performance enhancer; it helps men with ED achieve and maintain erections sufficient for satisfactory sexual intercourse. It requires sexual stimulation to be effective.
Consult your doctor to determine if Viagra is the right treatment for you. They can assess your health and discuss potential risks and benefits before prescribing it.
