Fildena 150 typically takes about 30 to 60 minutes to start working after oral consumption. Its active ingredient, Sildenafil Citrate, enhances blood flow to the penis, helping achieve and maintain an erection during sexual stimulation. For best results, take Fildena on an empty stomach with a full glass of water. Fatty meals or alcohol may delay its onset. The effects can last up to 4–6 hours, depending on individual health and metabolism. It’s important to take Fildena only once within a 24-hour period and under medical guidance to ensure safety and effectiveness.
