Abstract Disclosure: J.G. Sazon: None. D.V. Bawal: None. J.V. Chua: None. J. Reyes: None. Graves' disease (GD) constitutes a significant proportion of global thyrotoxicosis cases. Carbimazole is an ATD with a notably and a rare yet severe complication of ATD with substantial adverse implications for health, is agranulocytosis. This condition is reversible if recognized early and treated accordingly. We report a case of successful use of lithium prior to radioiodine ablation (RAI) in management of thyrotoxicosis in the context of Carbimazole-induced agranulocytosis. This is a case of a 38-year-old female newly-diagnosed with Graves' Disease presenting with palpitations. Diagnostics showed FT4 >100 (11.9 – 21.6 pmol/L), TSH at
