Could antidepressants change my personality and if so, how?

Rarely: Personality changes due to antidepressants are an extremely rare side effect. It may be as likely that without depressive symptoms, your responses and behaviors begin to change on their own.

Yes & no.: They don't change your inherent personality. BUT if depression has made changes in certain behaviors or how you interact without others those can be changed. For instances if you had been fun loving before depression but then became irritable, grumpy, sullen etc. these sx's may improve.
