Viagra, or sildenafil, enhances blood flow to the penis. This happens because it inhibits an enzyme called phosphodiesterase-5 (PDE5), allowing nitric oxide to work more effectively. Nitric oxide relaxes blood vessels, leading to increased blood flow and facilitating an erection.
Expect the effects to begin within 30-60 minutes of taking the pill, though this can vary depending on factors like food consumption and individual metabolism. The effects typically last for 4-5 hours. It’s important to remember that Viagra doesn’t cause erections without sexual stimulation; it only helps achieve and maintain one.
Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary. More serious side effects are rare, but you should seek immediate medical attention if you experience sudden vision loss, chest pain, or prolonged erection (priapism).
Before taking Viagra, consult your doctor. They’ll assess your health and discuss potential drug interactions. Certain heart conditions, low blood pressure, and the use of specific medications can make Viagra unsafe. Your doctor will determine the appropriate dosage for your needs.
Following your doctor’s instructions is critical. Avoid alcohol and grapefruit juice, as they can interact negatively with Viagra. Maintain a healthy lifestyle that includes regular exercise and a balanced diet to support overall health and well-being.
