Valif 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Vardenafil, which works by increasing blood flow to the pill, helping men achieve and maintain an erection when physical aroused. Vardenafil is a PDE5 inhibitor, which means it blocks the enzyme phosphodiesterase type 5 (PDE5), responsible for reducing blood flow to the pill during physical activity. Before using Valif 20 mg, inform your healthcare provider about any pre-existing conditions, especially heart problems, liver or kidney issues, and any allergies. https://www.genericday.com/valif-20-mg.html
