Fildena 100 tablets are used to treat erectile dysfunction in men. Erectile dysfunction is a medical condition that causes men to be unable to produce or maintain an erection. Along with sexual stimulation, Fildena helps fill the penis with blood by relaxing vascular muscles and increasing blood flow to the penis, which then leads to an erection. Therefore, the price of Fildena 100 mg is relatively low compared to drugs branded Sildenafil Citrate. The drug comes in a variety of doses that are prescribed depending on the patient's severity.
