Fildena 25 mg is a popular medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra, which works by increasing blood flow to the penis to help achieve and maintain an erection during sexual activity. Fildena 25 mg is often prescribed to men who require a lower dosage of sildenafil, offering a balance between efficacy and a reduced risk of side effects.
