What immediate treatment options should be initiated for a patient suspected of having thyroid storm?

The provided UK guideline context, "Thyroid disease: assessment and management" ¹, does not specifically detail immediate treatment options for a patient suspected of having a thyroid storm.

However, for adults with hyperthyroidism awaiting specialist assessment and further treatment, antithyroid drugs should be considered alongside supportive treatment ¹. Transient thyrotoxicosis without hyperthyroidism typically requires only supportive treatment, such as beta-blockers ¹.

Carbimazole is a commonly used antithyroid drug, but its use is subject to MHRA advice regarding contraception and the risk of acute pancreatitis ¹. Propylthiouracil may be considered for adults who experience adverse reactions to carbimazole, are pregnant or trying to become pregnant within the next six months, or have a history of pancreatitis ¹. Before initiating antithyroid drugs, a full blood count and liver function tests should be checked ¹.
