Manufactured erectile dysfunction medication is called Vidalista 60. It helps men achieve an erection by increasing blood flow to the penis. When you become sexually excited, it helps to relax the blood vessels in your penis, allowing blood to flow into it. About an hour before you intend to have sex, you should take it. Individual differences in productivity mean that working takes anywhere from half an hour to an hour. Take it all in at once. Never shatter, eat, or crush it. You can take a Vidalista with or without food, although it's best to take it at a set time.
