When taking Vidalista 20 mg , it is important to remember that it should be taken between 30 and 60 minutes before sexual activity. It is important to follow the instructions on the package and the patient information leaflet. If taken properly, Vidalista 20 mg is an effective treatment for erectile dysfunction. The active ingredient in Vidalista 20 mg is Tadalafil, which works by inhibiting phosphodiesterase-5 activity in the body. This allows more blood to flow to the penis and leads to an erection. It also helps men with BPH by improving blood flow and relieving symptoms. However, it is important to note that Vidalista is not a cure for erectile dysfunction, does not protect against sexually transmitted diseases, and does not increase a man's libido.
