Sildenafil is a medication commonly used to treat **erectile dysfunction (ED)**, a condition in which a person has difficulty achieving or maintaining an erection suitable for sexual activity. It belongs to a group of medicines called **phosphodiesterase type 5 (PDE5) inhibitors**. Sildenafil works by helping increase blood flow to the penis when sexual stimulation occurs, making it easier to achieve and maintain an erection. It does not increase sexual desire and does not cause an erection without sexual stimulation.
Sildenafil is generally effective for many people with ED, but it may not be suitable for everyone. In particular, it can interact dangerously with **nitrate medications** used for certain heart conditions. A healthcare professional should be consulted before using sildenafil to determine whether it is appropriate and safe.
