Sildenafil is prescribed for erectile dysfunction (ED).
It increases blood flow to the penis by relaxing blood vessels, making it easier to achieve and maintain an erection.
Most men notice effects within 30–60 minutes, lasting up to 4 hours.
It is not FDA-approved for women, though studies are ongoing for potential female use.
Daily use depends on prescribed dosage and your medical condition—consult a doctor before taking it regularly.
Avoid heavy meals, alcohol, and grapefruit juice, as they may reduce effectiveness.
