Vidalista 5 mg is a lower-dose formulation of tadalafil, primarily used to treat erectile dysfunction (ED) in men. It belongs to the class of PDE5 inhibitors, which work by relaxing the blood vessels in the penis, allowing increased blood flow during sexual activity. This helps men achieve and maintain an erection when sexually stimulated. However, Vidalista 5 mg is also prescribed for daily use in some cases, especially for those who prefer a consistent and long-lasting effect rather than planning sexual activity around a pill.
