It is the same med as Levitra, so if Levitra helps you, this should as well. If Levitra has not helped, this might anyway because it is taken differently.
The dose is less than Levitra, because you let it dissolve under your tongue, and it goes straight to the bloodstream, rather than having to be absorbed in the stomach/intestines.
Don't take the 5mg Cialis the same day. According to the instructions I remember, you could take the Staxyn multiple days in a row.
