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 ...
This allows Lugol's iodine to be produced in strengths varying from 2% to 15% iodine. Elemental iodine (I 2) is poisonous if taken orally in large amounts; 2–3 grams is a lethal dose for an adult human. [71] [72] Iodine vapor is very irritating to the eye, to mucous membranes, and in the respiratory tract.

Chemical element with atomic number 53 (I) Iodine, 53 I Iodine Pronunciation / ˈ aɪ ə d aɪ n, - d ɪ n, - d iː n / (EYE -ə-dyne, -din, -deen) Appearance lustrous metallic gray solid ...
Side effects may include allergic reactions, headache, vomiting, and conjunctivitis. [4] [1] Long term use may result in trouble sleeping and depression. [4] It should not typically be used during pregnancy or breastfeeding. [4] Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8]
USP Tincture of Iodine is defined in the U.S. National Formulary (NF) as containing in each 100 mL, 1.8 to 2.2 grams of elemental iodine, and 2.1 to 2.6 grams of sodium iodide. Alcohol is 50 mL, and the balance is purified water. This "2% free iodine" solution has 0.08 mol/L of I 2, which provides about 1 mg of free iodine per 0.05 mL drop. The ...
Used to prevent iodine deficiency, this salt is one of the major uses of the element iodine. [1] The United States Food and Drug Administration suggests a limit of intake to 50 mg/head/day. [ 2 ] Although EDDI is generally recognized as safe (GRAS) only as a nutrient source of iodine, administration of EDDI also has preventative effects on foot ...
Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements typically declines with greater atomic mass.
Many of the side effects are due to the hyperosmolar solution being injected. i.e. they deliver more iodine atoms per molecule. The more iodine, the more "dense" the X-ray effect. [citation needed] Organic iodine molecules used for contrast include iohexol, iodixanol, and ioversol. Iodine-based contrast media used nowadays are water-soluble.
