Recommendations on the use of potassium iodide as a thyroid-blocking agent in radiation accidents: an FDA update. People over the age of 40 should only take potassium iodide if their public health officials state that there will be a very high amount of radioactive iodine contamination. As such, it doesn’t prevent radioactive iodine from entering your body — it only stops your thyroid from absorbing the iodine.

Several drugs, such as captopril and enalapril can cause hyperkalaemia and this effect may be enhanced if potassium iodide is also administered. Transient hypothyroidism during this early period of brain development can result in loss of intellectual capacity. For neonates who have been administered potassium iodide in the first few weeks of life TSH levels and, if necessary, T4 levels should be monitored and appropriate replacement therapy given. The human body is able to metabolise doses even manyfold higher than the daily recommended dose, mainly via urine, enterohepatic circulation and salivary glands (after the administration of one single dose of 3 g potassium iodide the dose is completely eliminated after 75 hours, 89% via urine).In another study in rats, the administration of high daily iodine doses led to incomplete parturition, failure of lactation and reduced mothering activities.

This dose should be administered on or before the day of the investigation and then daily until the estimated activity of radioiodine in the body has fallen to appropriate levels. In cases of exposure to radioiodine from nuclear accidents, dosing of potassium iodide should be based on emergency plans and predetermined operational intervention levels. Because of this, it’s important to give children, especially newborns, potassium iodide during an emergency.It does not protect the rest of your body because it’s not a general radioprotective agent, according to the Food and Drug Administration (FDA). Pregnant women with active hyperthyroidism must not take potassium iodide because of the risk of foetal thyroid blockage. When a nuclear accident or (God forbid) a nuclear attack happens, iodine tablets can help protect you. Hypersensitivity reactions such as skin rashes, swollen salivary glands, headache, and bronchospasm can be mild or severe and may be dose dependent. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme.

First off- as we mentioned before, you are supposed to hold off taking the doses until emergency officials tell you to. We presented quite a lot of information, but as always: if you have any questions let us know and we would be happy to help. In some radiation emergencies, usually nuclear power plant accidents, radioactive iodine may be released into the environment and enter the body through breathing or eating it. It’s usually not advised to give doses to household animals given their short lifespans and how long symptoms of thyroid radiation exposure may take to develop.Tablets in two strengths, 130 milligram (mg) and 65 mg (The tablets may be cut into smaller pieces for lower doses.
