What is Viagra and How Does It Work?
Viagra, also known by its generic name Sildenafil, is a prescription medication used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis during sexual stimulation, helping a man achieve and maintain an erection.
Viagra does not increase sexual desire; it helps the body respond more effectively to natural arousal. It belongs to a class of drugs called PDE5 inhibitors and is usually taken 30–60 minutes before sexual activity.
Disclaimer: Always consult with a licensed physician before using Viagra. Do not use if you’re taking nitrates or have heart conditions.
