The effects of Fildena typically last for approximately 4 to 6 hours. During this timeframe, individuals may experience an improved ability to achieve and maintain an erection when sexually aroused. However, the duration can vary based on factors like metabolism, individual response, and dosage. It's important to note that Fildena 100 mg pill doesn't cause a continuous erection; sexual stimulation is still necessary for the medication to work effectively. To ensure safety and effectiveness, it's recommended to adhere to the prescribed dosage and consult a healthcare professional before using Fildena.
