We describe the case of a man with a 34-year history of BPAD type-1 and a 2-year history of ESKD secondary to lithium-induced nephropathy who experienced a manic relapse. He previously responded well to lithium but, following a deterioration in kidney function, was switched to olanzapine and sodium valproate. This precipitated a period of instability, which culminated in a treatment-resistant manic episode requiring hospital admission. After a multidisciplinary team discussion, lithium therapy was restarted and provided remission. This was achieved safely through a reduced dosing schedule of three times a week post dialysis, slow dose titration and blood level monitoring prior to each dialysis session. ER -
