Fildena Double 200 mg tablets are a high-strength medication primarily used to treat erectile dysfunction (ED) in men. They contain Sildenafil Citrate, a PDE5 inhibitor that works by increasing blood flow to the penis, helping achieve and maintain a firm erection during sexual stimulation. This tablet is typically recommended for men who do not respond well to lower doses of sildenafil. Fildena Double 200 mg usually starts working within 30 to 60 minutes after consumption, and its effects may last up to 4–6 hours.
