Potassium iodide is medicinally supplied in 130 mg tablets for emergency purposes. Potassium iodide may also be administered as a "saturated solution of potassium iodide" (SSKI) which in the U.S.P. generic formulation contains 1000 mg of KI per mL of solution. This represents 333 mg KI and about 250 mg iodide (I <sup>-</sup>) in a typical adult dose of 5 drops, assumed to be ⅓ mL.. Thus, two (2) drops of U.S.P. SSKI solution is equivalent to one 130 mg KI tablet (100 mg iodide).
