Potassium iodide is taken by mouth.
It may be taken as an oral solution, syrup, uncoated tablet, or enteric-coated tablet. However, the enteric-coated tablet form may cause serious side effects and its use is generally not recommended. Some brands of the oral solution are available without a prescription. Use them only as directed by state or local public health authorities in case of a radiation emergency. Other forms and strengths of potassium iodide are available only with your doctor's prescription.
