Fildena 50 mg is a brand-name formulation containing sildenafil citrate 50 mg, a medicine used to treat erectile dysfunction (ED) in men. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. It works by increasing blood flow to the penis when sexual stimulation occurs, helping achieve and maintain an erection. It does not increase sexual desire and does not cause an erection without sexual stimulation. Fildena 50 mg is generally taken before anticipated sexual activity, according to a healthcare professional's instructions.
