Fildena 25 mg works by relaxing the smooth muscles of blood vessels in the penile region. This improves circulation when a man is sexually aroused. It is important to note that the tablet does not cause an automatic erection; sexual stimulation is required for it to be effective. The 25 mg dose is generally considered a low starting dose, often prescribed for men who are new to sildenafil, elderly patients, or those who may be sensitive to higher doses.
