• VARDENAFIL tablets have been clinically shown to improve erectile function, even in men who had other health factors, like high cholesterol, high blood pressure, or diabetes.
• Many men taking VARDENAFIL tablets reported having greater success than men taking placebo (sugar pill) at maintaining their erections long enough for sexual activity
VARDENAFIL tablets are a proven, effective treatment that works for many men.
