Fildena 150 Sildenafil is a medication prescribed for the treatment of erectile dysfunction (ED). It contains Sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that enhances blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Fildena 150 mg is a higher dose, usually recommended for individuals who may need a more potent option to manage their condition effectively. It is typically taken about 30 to 60 minutes before sexual activity, with effects lasting up to four to six hours. Common side effects include headaches, flushing, and indigestion. As with any medication, it should be used under medical supervision to ensure safety and effectiveness, especially to avoid interactions with other medications or underlying health conditions.
