Paroxetine and Galactorrhea

Abstract

The authors report a case of galactorrhea following antidepressant treatment where paroxetine might be responsible. Paroxetine is a selective serotonergic reuptake inhibitor (SSRI). Galactorrhea occasionally is a dopamine-mediated side effect observed with neuroleptic drugs. However, the ability to produce extrapyramidal side effects is known for tricyclic as well as for SSRIs. Thus the potential of SSRIs to induce dopamine-dependent side effects is a clinical reality and it was not surprising to observe galactorrhea due to paroxetine. However, in a review of the literature no reported cases of galactorrhea associated with paroxetine were found.
