Men with erectile dysfunction suffer from persistent problems achieving and maintaining an erection long enough for meaningful sexual activity. This problem is treated with a prescription drug called Vidalista 20. Tadalafil, the medication's main ingredient, improves blood flow to the penis to help create a successful penile erection. Vidalista 20 can be taken either way, with or without food. When taking it, you should adhere strictly to your doctor's instructions. You should wait about 30-60 minutes before your intended sexual activity. Never crush, eat, or break it. Vidalista 20 can be taken with or without food, though it is recommended to take it at a predetermined time.
