•Iodine-based imaging contrast can sometimes cause
iodine-induced thyrotoxicosis and can interfere with
iodide uptake in the thyroid, compromising radio-iodine
therapy
•
•When considering thionamide therapy, methimazole is a
good first option—longer duration of action, more
rapid efficacy, and better tolerated (lower incidence of SE)
•
•Consider labetalol if beta blocker therapy is needed
in patients who abuse cocaine
•
•Pregnancy is an absolute contraindication to
radio-iodine therapy
•
•Propylthiouracil may be a better treatment choice in
pregnant
patients
