A substantial amount of sildenafil citrate, which is mostly used to treat erectile dysfunction (ED), is present in Fildena 120. Impotence, another name for erectile dysfunction, is the inability of men to attain an erection. When sexual excitement takes place, this procedure aids a man in achieving an erection. Consequently, the condition is being treated. But, since taking more than one dose per day can result in an overdose, avoid doing so. Pay attention to your doctor's recommendations regarding the dosage that you should take. Fildena is a prescription medication, thus getting checked out by a physician is required before taking it. The tablet should be swallowed whole, without breaking or chewing, along with a glass of water.
