Fildena 100mg is one of the most widely used generic medications for the treatment of erectile dysfunction (ED), offering a high-strength dose of sildenafil citrate, the same active ingredient found in the well-known brand Viagra. Manufactured by Fortune Healthcare, Fildena 100mg works by relaxing the blood vessels and enhancing blood flow to the penile tissues, enabling men to achieve and maintain a firm erection when sexually aroused. This dose is typically prescribed for men who have not experienced sufficient results with lower doses such as 25mg or 50mg. Fildena 100mg usually takes 30 to 60 minutes to begin working and provides an effect that can last up to 4 to 6 hours, depending on the individual.
