Male erectile dysfunction (ED) is treated with Fildena 50. The inability to get and maintain an erection during sexual activity is known as impotence, or ED. The male genital organ's abnormal blood flow is the root cause of ED. Fildena 50 is a prescription medication that you should take for the recommended amount of time and duration as prescribed by your physician. A full Fildena 50 can be taken with a glass of water. This drug should be taken 30 to 60 minutes before engaging in sexual activity. You shouldn't take the prescription more than once a day, even if you missed a dose.
