Hello and thank you for writing to us. My name is Leah. "Augmenting" or adding Celexa to your current Wellbutrin regimen is safe. Wellbutrin does not affect Serotonin levels like the Celexa does, therefore combining the two is sometimes advantageous. Also, the fact that you stopped Celexa cold turkey could have had something to do with the spike in your anxiety as quitting medications like this can produce withdrawal effects. but now, weeks later with the anxiety still present, it is worth considering the readdition of the med that worked so well for you before.
I hope this helps,
Thanks. Anything else I can help with?
I would consult your physician prior to adding the Celexa as this advice does not substitute them assessing the proper dose for you. However, a starting dose of Celexa of 10mg would be the ideal and likely place to start.
