Men with erectile dysfunction (ED) are the main patients for the medicine Fildena 200 mg. Sildenafil Citrate 200 mg is present in it.  It is best to take Fildena on an empty stomach or right after a light meal as taking it with a big meal may cause it to take longer to start working. Men with erectile dysfunction can benefit from using Fildena 200, especially those who might need a greater dosage to see the best effects. However, because of the higher dosage, it should only be administered under medical supervision.
