It is approved as a specific blocker of thyroid uptake of radioiodine to reduce the risk of thyroid cancer in susceptible populations. The indications for its use are complex and initiation and maintenance of therapy require great attention to the details of the circumstances of the exposure to limit harm that may result from either undertreatment or overtreatment.
