This article explains the real working time of sildenafil, what affects its speed, and how to use it correctly.


What Is Sildenafil?

Sildenafil is a medicine used to treat erectile dysfunction (ED). It works by improving blood flow to the penis, which helps men get and maintain an erection during sexual activity.

It is important to understand that sildenafil:

  • Does not work instantly

  • Does not increase sexual desire

  • Works only with sexual stimulation


How Long Does Sildenafil Take to Start Working?

⏱ Average Time: 30 to 60 Minutes

For most men, sildenafil starts working within 30 to 60 minutes after taking the tablet.

Some people may feel the effect in as little as 20 minutes, while others may need up to one hour. This difference depends on food, body type, and overall health.
