• It is only taken before sexual activity.
• It works by increasing blood flow to the penis, helping men achieve an erection.

• Always read the patient information leaflet before use.

What Causes Erectile Dysfunction?

Erectile dysfunction has several causes and is more common in men over 40. Occasional difficulties with erections are normal and may be due to stress, tiredness, anxiety, or excessive alcohol consumption.

Medical conditions can also contribute to erectile dysfunction, causing persistent issues. These may include blood vessel problems, high blood pressure, high cholesterol, diabetes, spinal injuries, or nerve damage. Treating the underlying condition is important; however, Sildenafil can help provide effective treatment for erectile dysfunction itself.

How does Sildenafil work?

For an erection to occur, sexual arousal is required. During stimulation, nerve signals cause the muscles in the penis to relax, allowing blood to flow in. This expands the penis and causes an erection.

When erectile dysfunction is caused by restricted blood flow, Sildenafil helps by widening the blood vessels. This allows more blood to reach the penis, making it easier to achieve and maintain an erection when aroused. Sildenafil will only work when you are sexually stimulated.
