Fildena 25mg, containing sildenafil citrate, is a popular medication for treating erectile dysfunction (ED). When taken approximately 30 to 60 minutes before sexual activity, its effects typically last for 4 to 6 hours. During this time, Fildena helps increase blood flow to the penis, making it easier to achieve and maintain an erection when sexually aroused. However, the medication’s duration can vary depending on factors such as individual metabolism, health conditions, and other medications being taken. It is important to follow the recommended dosage and consult a doctor to ensure optimal results and minimize potential side effects.
