Sildenafil Citrate is the usual ingredient in Fildena 50. This is a dosage that is frequently recommended for the treatment of erection. Usually, Fildena 50 is taken orally together with a glass of water. Generally speaking, the drug should be taken 30 to 1 hour before any scheduled sexual activity. Meals heavy in fat should be avoided to maximize the medication's rapid and efficient action. Effectiveness: Although Fildena 50 does not enhance sexual desire, it can assist many men with ED in achieving and maintaining an erection. An erection still requires a sexual stimulus to occur.
