In order to treat the root causes of erectile dysfunction, the natural ingredients in Fildena Pills act in concert. Sildenafil, a potent substance obtained from the PDE5 plant, is one notable ingredient. In order to help men obtain and maintain hard erections, it works by increasing blood flow to the penile tissue. If your doctor so prescribes, this medication may also be used to treat other ailments. The adverse effects of fildena include headaches, impaired vision, upset stomachs, stuffy noses, back discomfort, and flushing in the face, neck, or chest. Not every adverse impact is included in this list. When taking Fildena, always listen to your doctor and do as advised. Most often, when a medication is taken with food or another medication, drug interactions happen.
