How It Works & Treatment Guide

What is sildenafil?

Sildenafil is a prescription medicine commonly used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to help achieve and maintain an erection when sexually stimulated.

Sildenafil belongs to a group of medicines known as PDE5 inhibitors and has been widely used for many years as a safe and effective erectile dysfunction treatment following appropriate medical assessment.

What is sildenafil used for?

Sildenafil is primarily prescribed for the treatment of erectile dysfunction. It helps improve blood flow to the penis, supporting the body's natural response to sexual stimulation.

It may be suitable for men experiencing:

• Difficulty achieving an erection
• Difficulty maintaining an erection
• Reduced erectile firmness
• Loss of sexual confidence

Many patients choose generic sildenafil as a reliable and effective option to manage symptoms of ED.

How sildenafil works

Sildenafil works by relaxing blood vessels and improving circulation. When a man is sexually stimulated, this increased blood flow helps produce and maintain an erection.

It does not cause an automatic erection and sexual stimulation is still required for the medicine to work.

Is sildenafil the same as Viagra?

Viagra is a branded version of sildenafil. Generic sildenafil contains the same active ingredient and provides the same effect as branded Viagra.

Both treatments are regulated and prescribed following appropriate medical assessment, and many patients choose the generic version due to its affordability and accessibility.
