Men with erectile dysfunction (ED) are the main patients for the drug fildena. The usual dosage for ED is Fildena 50 or Fildena 100 mg, given as needed, ideally an hour before engaging in sexual activity. Tolerance and efficacy can be taken into consideration while adjusting the dosage. It’s important to talk about any underlying medical concerns, such as liver or kidney problems, cardiovascular disorders, or conditions that raise the risk of priapism (painful erections lasting more than four hours), before taking Fildena.
