For "Iodine" (capsule, iodized oil) as found in the WHO Model List of Essential Medicines[1], see Lipiodol.
Iodine is a chemical element with many uses in medicine, depending on the form. Elemental iodine and iodophors are topical antiseptics.[2] Iodine, in non-elemental form, functions as an essential nutrient in human biology (see iodine in biology).[3] Organic compounds containing iodine are also useful iodinated contrast agents in X-ray imaging.[4]
Common side effects when applied to the skin include irritation and discoloration.[2] Supplementation during pregnancy is recommended in regions where deficiency is common, otherwise it is not recommended.[1] Iodine is an essential trace element.[1]
