Vidalista 20 mg is the most widely used pill to treat erectile dysfunction. Other problems with male sexual function are also covered. Tadalafil is the name of the medication's salt variant. By improving blood flow to the penis, it helps a man maintain his erection, which is how it is usually used to enhance sexual activity. Although everyone's workday varies, it typically lasts between 30 and 60 minutes. Vidalista 20 can be taken either way: with or without food. Abrupt heart palpitations, blood in the urine, urinary tract infections, blue-tinged or impaired vision, headaches that don't go away, and fainting are examples of severe side effects.
