Erectile dysfunction (ED) is a common condition that affects many men. It can have a significant impact on your quality of life and relationships. Fortunately, effective treatments are available. Sildenafil, a Phosphodiesterase Type 5 Inhibitor, is one of the most commonly prescribed medications for treating ED.
Sildenafil is a medication used to treat erectile dysfunction by increasing blood flow to the penis, helping you achieve and maintain an erection when sexually aroused. It’s the active ingredient in Viagra and works by relaxing the blood vessels in your penis, allowing for better blood flow.
Sildenafil is typically taken as needed, about 30 to 60 minutes before sexual activity. The standard dose is one tablet, which can be taken with or without food. Avoid taking more than one dose within 24 hours. It’s important to follow your healthcare provider’s instructions and to read the manufacturer’s leaflet supplied with your sildenafil tablets.
