NCT05512715

Brief Summary

A prospective randomised controlled open label, single centre study. subjects will be randomised into lithium or carbimazole arms in a 1:1 ratio. Lithium arm will receive tab Lithium Carbonate 300mg daily while Carbimazole arm will receive tab Carbimazole 10mg daily for a duration of two months prior to radioactive iodine treatment. Changes in the thyroid hormone levels at 2 months of treatment and at months 1,3 and 6 following radioactive iodine will be evaluated.
