[Psychosis after lactation inhibition with cabergoline]

This case report presents a woman with post-partum depression treated with cabergoline for lactation inhibition who developed psychotic symptoms. She was admitted with moderate depression following a suicide attempt, and started on cabergoline and sertraline, with initial improvement of the depressive symptoms. Six days after starting cabergoline, she developed severe psychotic symptoms. Symptoms rapidly improved with antipsychotics and ECT. Due to the long half-life of cabergoline, this case potentially highlights a rare but serious adverse effect of cabergoline.
