Hello, these are exactly the same drug, just different brand names. Efexor is made by Pfizer and Ireven is made by Teva but they are both venlafaxine.
Drug companies often make the exact same drug and then give them a brand name unique to that company.
Take 2 tablets in the morning just as you have been.
Hope that helps,
Best wishes.
