**********************************************
Regarding Wellbutrin: The AVERAGE half-life of bupropion (the generic name of Wellbutrin) is about 14 hours; HOWEVER, bupropion has several metabolites (substances it is broken down into in the body) that have much longer half-lives. I don't have the exact numbers in front of me at the moment, but if I remember correctly, one of the metabolites has an average half-life of approximately 37 hours. Since these are averages, there is a wide range that can vary according to a number of factors, including concomitant medications and the liver's ability to metabolize the medications. As you probably know, the half-life is the time it takes for HALF of the substance to leave your body. I don't know how Strattera interacts with Wellbutrin, but since they both block the reuptake of norepinephrine, which can cause anxiety, I believe the likelihood of each one potentiating the other's anxiogenic effects is quite high. I hope you do well on Strattera. Medicines like this are long overdue.
