Though galactorrhoea caused by the use of paroxetine has been reported earlier, the commonly perceived cause is hyperprolactinemia.[4] Hyperprolactinemia can be caused by two distinct mechanisms namely-presynaptic inhibition of dopamine discharge by serotonergic receptors or the direct stimulation of hypothalamic post synaptic serotonergic receptors.[2, 5] The peculiarity of the case lies in the fact that serum prolactin levels were not raised. This evidence concerns the gene PRL and hyperprolactinemia.
