Fildena 200 mg is prescribed for erectile dysfunction (ED) in men who experience difficulty achieving or maintaining an erection. This high-dose medication contains sildenafil citrate, a potent PDE5 inhibitor that relaxes blood vessels and enhances blood flow to the penile, allowing for a firm erection during sexual activity. Fildena 200 mg is typically recommended for men with more severe ED, where lower doses may not be as effective. Its fast action, usually within 30-60 minutes, and lasting effects of up to 4-6 hours make it a powerful solution. However, it should be taken under medical supervision to ensure safe use.
