Euthyroid goitre — i.e. the formation of a goitre despite normal thyroid functioning
Hypothyroidism — a deficiency of thyroid hormone. Hair loss/hair thinningUnknown
Sexual dysfunction
HypoglycemiaLithium carbonate can induce a 1–2 kg of weight gain. Weight gain may be a source of low self-esteem for the clinically depressed.In addition to tremors, lithium treatment appears to be a risk factor for development of parkinsonism-like symptoms, although the causal mechanism remains unknown.Most side effects of lithium are dose-dependent. The lowest effective dose is used to limit the risk of side effects. Hypothyroidism
The rate of hypothyroidism is around six times higher in people who take lithium. Low thyroid hormone levels in turn increase the likelihood of developing depression. People taking lithium thus should routinely be assessed for hypothyroidism and treated with synthetic thyroxine if necessary.Because lithium competes with the antidiuretic hormone in the kidney, it increases water output into the urine, a condition called nephrogenic diabetes insipidus. Clearance of lithium by the kidneys is usually successful with certain diuretic medications, including amiloride and triamterene. It increases the appetite and thirst ("polydypsia") and reduces the activity of thyroid hormone (hypothyroidism). The latter can be corrected by treatment with thyroxine and does not require the lithium dose to be adjusted. Lithium is also believed to permanently affect renal function, although this does not appear to be common. Pregnancy and breast feeding
Lithium is a teratogen, causing birth defects in a small number of newborn babies.
7 Up
As with cocaine in Coca-Cola, lithium was widely marketed as one of a number of patent medicine products popular in the late-19th and early-20th centuries, and was the medicinal ingredient of a refreshment beverage. Charles Leiper Grigg, who launched his St. Louis-based company The Howdy Corporation, invented a formula for a lemon-lime soft drink in 1920. The product, originally named "Bib-Label Lithiated Lemon-Lime Soda", was launched two weeks before the Wall Street Crash of 1929. It contained the mood stabilizer lithium citrate, and was one of a number of patent medicine products popular in the late-19th and early-20th centuries. Its name was soon changed to 7 Up. All American beverage makers were forced to remove lithium in 1948. Despite the 1948 ban, in 1950 the Painesville Telegraph still carried an advertisement for a lithiated lemon beverage. Salts and product names
Many different lithium salts can be used as medication, including lithium carbonate, lithium acetate, lithium sulfate, lithium citrate, lithium orotate and lithium gluconate. Lithium carbonate (Li2CO3), sold under several trade names, is the most commonly prescribed, while lithium citrate (Li3C6H5O7) is also used in conventional pharmacological treatments. Lithium orotate (C5H3LiN2O4), has been presented as an alternative. Lithium bromide and lithium chloride have been used in the past as table salt; however, they fell out of use in the 1940s, when it was discovered they were toxic in those large doses.
