The provided UK guideline context, "Thyroid disease: assessment and management" , 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 . Transient thyrotoxicosis without hyperthyroidism typically requires only supportive treatment, such as beta-blockers .

Carbimazole is a commonly used antithyroid drug, but its use is subject to MHRA advice regarding contraception and the risk of acute pancreatitis . 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 . Before initiating antithyroid drugs, a full blood count and liver function tests should be checked .
