Is Duralast 30 meant for penis stiffnessWhat are the side effects using this tablet I m an Asian Male, 33 years old married for 3 years. Since a year,as my wife & I were trying to conceive, I have had problems with my penis maintaining erection during intercourse.Also, there has hardly been any penetration. I had a visit to the doc,who ruled out any issues with my penis.He has recommended to use Duralast 30(Dapoxetine tablets) at least half an hour before sexual intercourse. Does this tablet act like a Viagr a? Are there any side effects from using this often ?
