This is a type of quick-dissolving tab that is used to treat male impotence. It is available in the form of a mint flavored oral lozenge that is placed under your tongue to dissolve. Within fifteen minutes, or less, this medication will begin working and then it will for around thirty-six hours. This occurs so quickly because of the way that it is ingested and is beneficial as you do not have to plan for sex hours in advance. On the other hand, if you were to take a pill it would take around forty minutes before it would begin working. This is dependent on the type of meal that you eat. For instance, if you eat a meal that is high in saturated fat, it will take longer for the pill to begin working. Thankfully though, with the soft tabs you do not have to worry about what type of meal you eat since the medicine does not pass through your digestive system.
