Store in airtight containers. Physicochemical Characteristics (Latest modification: 21-Mar-2004) Turbidity Zinc chloride almost always contains some oxychloride which produces a slightly turbid aqueous solution. Turbid solutions, except when intended for ophthalmic use, may be cleared by adding gradually a small amount of dilute hydrochloric acid. Solutions of zinc chloride should be filtered through asbestos or sintered glass, since they dissolve paper and cotton wool.

Adverse Effects, Treatment, and Precautions (Latest modification: 22Jul-2008) The most frequent adverse effects of zinc salts (the gluconate and sulfate) given orally are gastrointestinal and include abdominal pain, dyspepsia, nausea, vomiting, diarrhoea, gastric irritation, and gastritis. These are particularly common if zinc salts are taken on an empty stomach, and may be reduced by giving them with meals. In acute overdosage zinc salts are corrosive, due to the formation of zinc chloride by stomach acid; treatment consists of giving milk or alkali carbonates and activated charcoal. The use of emetics or gastric lavage should be avoided. Prolonged use of high doses of zinc supplements, orally or parenterally, leads to copper deficiency with associated sideroblastic anaemia and neutropenia; full blood counts and serum cholesterol should be monitored to detect early signs of copper deficiency. Zinc toxicity has occurred after the use of contaminated water in haemodialysis solutions. High serum zinc concentrations may be reduced by using a chelating drug such as sodium calcium edetate ( ). Metal fume fever is an occupational disease associated with inhalation of freshly-oxidised metal fumes, most commonly from zinc, iron or copper. It is characterised by chills, fever, cough, dyspnoea, myalgia, and chest pain, and is generally self-limiting and does not appear to be associated with longterm sequelae. (last reviewed 2010-08-23; last modified 2008-07-22) Effects on the blood (Latest modification: 04-Mar-2006) There have been reports1-3 of anaemia, leucopenia, and neutropenia in patients consuming excessive amounts of zinc supplements for acne. A patient given zinc-containing enteral feeds as well as zinc supplementation was diagnosed with sideroblastic anaemia due to zinc toxicity.4 All patients were copper-deficient,1-4 despite supplementation with copper in one case.4 (last reviewed 2010-08-23; last modified 2006-03-04) 1. 1.

PubMed Effects on the senses (Latest modification: 02-Jan-2011) The FDA's adverse event reporting system received 131 reports of anosmia (loss of the sense of smell) associated with the use of intranasal zinccontaining preparations (Zicam).1 These products contained zinc gluconate, were marketed in the USA from 1999 to June 2008, and were used to prevent and treat cold symptoms, usually for about 3 days. Loss of smell was often associated with an initial burning sensation in the nose, and occurred soon after intranasal use; anosmia was long-lasting or permanent in most cases. Loss of taste was also reported in some patients. (last reviewed 2010-08-23; last modified 2011-01-02) 1. 1. FDA. Zinc-containing intranasal cold products (marketed as Zicam) and anosmia.

PubMed Porphyria (Latest modification: 14-Nov-2011) The Drug Database for Acute Porphyria, compiled by the Norwegian Porphyria Centre (NAPOS) and the Porphyria Centre Sweden, classifies zinc sulfate as not porphyrinogenic; it may be used as a drug of first choice and no precautions are needed.1 (last reviewed 2010-08-23; last modified 2011-11-14) 1. 1. The Drug Database for Acute Porphyria. Available at: online (accessed 07/10/11) Interactions (Latest modification: 08-May-2009) The absorption of zinc may be reduced by iron supplements (see also Absorption, under Pharmacokinetics, ), penicillamine, phosphorus- containing preparations, and tetracyclines. Zinc supplements reduce the absorption of copper, fluoroquinolones (see Antacids and Metal Ions, under Interactions of Ciprofloxacin, ), iron, penicillamine, and tetracyclines ( ). (last reviewed 2010-08-23; last modified 2009-05-08) Pharmacokinetics (Latest modification: 26-Jan-2006) Absorption of zinc from the gastrointestinal tract is incomplete, and is reduced in the presence of some dietary constituents such as phytates. Bioavailability of dietary zinc varies widely between different sources, but is about 20 to 30%. Zinc is distributed throughout the body with the highest concentrations found in muscle, bone, skin, eye, and prostatic fluids. It is primarily excreted in the faeces, and regulation of faecal losses is important in zinc homoeostasis. Small amounts are lost in urine and perspiration. (last reviewed 2010-08-23; last modified 2006-01-26) Absorption (Latest modification: 07-Nov-2007) Although zinc deficiency (see Deficiency States, under Uses and Administration, ) in some cases may be due to inadequate dietary intake, inhibitors of zinc absorption may also be causative.1 Phytates, which are present in cereals, corn, legumes, and rice, inhibit zinc absorption. The animal protein in beef, eggs, and cheese counteracts the inhibitory effect of phytate, whereas the casein in milk decreases zinc absorption. Proteins also often contain other constituents such as inorganic phosphate that can negatively affect zinc absorption. Long-term use of calcium supplements has no effect on zinc status, but dietary calcium may form insoluble complexes with phytate and zinc, thus decreasing the absorption of zinc. Iron can reduce zinc absorption, although the effect is apparent only at a very high ratio of iron to zinc, and in aqueous solution, which suggests that iron fortification of foods will not affect zinc absorption. Although it is possible that iron supplementation could affect mechanisms of zinc uptake and transport, studies have not found such an effect, and long-term iron supplementation is not considered to impair zinc status. Zinc can form complexes with ligands or chelators; if the complex is readily absorbed, this can increase zinc absorption. Edetic acid has been found to have variable effects on zinc status depending on the ratio of edetic acid to other cations and phytate, which compete for complex formation with zinc. Histidine also chelates with zinc and can increase plasma zinc concentrations; however, the ratio of histidine to zinc is important because high doses of histidine may enhance the urinary excretion of zinc. Methionine may improve zinc absorption, although evidence is limited. Adding organic acids such as citrate to foods can enhance zinc absorption; zinc citrate has been used as a dietary supplement.

PubMed Human Requirements (Latest modification: 04-Mar-2006) UK and US recommended dietary intake (Latest modification: 03-Sep-2010) In the UK dietary reference values (DRV)1 and in the USA recommended dietary allowances (RDA)2 (see Human Requirements, ) have been published for zinc. In the UK the reference nutrient intake (RNI) for adult males and females is 9.5 and 7.0 mg daily respectively; values are also given for infants and children of varying ages and for lactating women. The Expert Group on Vitamins and Minerals3 have established a safe upper level (SUL) for zinc of 25 mg daily. In the USA the RDA for adults is 11 mg daily for men and 8 mg daily for women.2 The tolerable upper intake level is 40 mg daily. WHO recommend lower limits of the safe ranges of population mean intakes of dietary zinc for 3 categories of diets based on high, moderate, and low zinc bioavailability: values are 4.0, 6.5, and 13.1 mg dietary zinc daily for women, and 5.6, 9.4, and 18.7 mg dietary zinc daily for men, respectively.4 They recommend an upper limit of the safe range of population mean intakes of zinc of 35 mg daily for women, and 45 mg daily for men.

Uses and Administration (Latest modification: 07-Nov-2011) Zinc is an essential element of nutrition and traces are present in a wide range of foods. It is a constituent of many enzyme systems and is present in all tissues. Features of zinc deficiency include growth retardation and defects of rapidly-dividing tissues such as the skin, the immune system, and the intestinal mucosa. Water-soluble zinc salts are used as supplements to correct zinc deficiency; for example, in malabsorption syndromes, during parenteral feeding, in conditions with increased body losses (trauma, burns, and protein-losing states), and in acrodermatitis enteropathica (a rare genetic disorder characterised by severe zinc deficiency). They have been tried in the treatment of a large number of conditions that may be related to zinc deficiency. Doses of zinc salts are usually expressed in terms of elemental zinc, and the following salts contain about 50 mg of zinc: zinc acetate (dihydrate) 168 mg zinc chloride 104 mg zinc citrate (trihydrate) 160 mg zinc gluconate 348 mg zinc lactate 186 mg zinc sulfate (heptahydrate) 220 mg The approximate number of millimoles of zinc contained in these salts are: 4.6 mmol in 1 g zinc acetate (dihydrate) 7.3 mmol in 1 g zinc chloride 4.8 mmol in 1 g zinc citrate (trihydrate) 2.2 mmol in 1 g zinc gluconate 4.1 mmol in 1 g zinc lactate 3.5 mmol in 1 g zinc sulfate (heptahydrate) In deficiency states, zinc is usually given orally as the sulfate, the sulfate monohydrate, or the gluconate, in doses of up to 50 mg of elemental zinc three times daily. When intravenous supplements are required, zinc chloride or zinc sulfate may be given; a suggested dose for parenteral nutrition is 6.5 mg of elemental zinc (100 micromoles) daily. Oral zinc salts, commonly the acetate, may be used as copper absorption inhibitors in Wilson's disease ( ). The usual adult dose is 50 mg three times daily up to a maximum of five times daily. An effective dose in pregnant women is usually 25 mg three times daily; however, dosage is adjusted based on copper concentrations. For doses in children, see Administration in Children, under Deficiency States, and Diarrhoea, . Zinc sulfate is used topically in a variety of skin conditions mainly for its astringent properties. The insoluble zinc salts, commonly the oxide ( ), are used similarly. A 1.2% solution of zinc acetate is used topically with erythromycin in the treatment of acne vulgaris ( ). Zinc sulfate is also used as an astringent in eye drops. Zinc chloride has been used for its powerful caustic and astringent properties, usually in very dilute solution, in, for example, mouthwashes. Zinc citrate and zinc lactate are used in preparations for oral care and as a dietary supplement. Polaprezinc ( Homoeopathy ) is also used as a source of zinc. Zinc and its salts have been used in homoeopathic medicines. (last reviewed 2010-08-23; last modified 2011-11-07) Administration in children (Latest modification: 24-Sep-2013) Zinc can be given to children to prevent and treat deficiency or as a copper absorption inhibitor in Wilson's disease ( ). The following doses are expressed as elemental zinc. In deficiency states, zinc can be given orally according to weight: less than 10 kg, 22.5 mg daily 10 to 30 kg, 22.5 mg once to three times daily over 30 kg, 45 mg once to three times daily The BNFC suggests an oral dose of zinc 1 mg/kg daily for neonates. When intravenous supplements are required, suggested doses of zinc for children vary between countries. UK licensed product information recommends a dose of 250 micrograms/kg (up to a maximum of 3.75 mg) daily for children weighing 40 kg or less; children weighing more than 40 kg should receive the adult dose (see ). In the USA, licensed product information recommends a dose of 300 micrograms/kg daily for preterm neonates weighing up to 3 kg, and 100 micrograms/kg daily for full term infants and children up to 5 years. Adult doses may be used in older children. In Wilson's disease, zinc is given orally according to age: 1 to 6 years, 25 mg twice daily 6 to 16 years and body-weight under 57 kg, 25 mg three times daily over 16 years or body-weight above 57 kg, 50 mg three times daily For acrodermatitis enteropathica, the BNFC suggests an initial oral dose of zinc 0.5 to 1 mg/kg twice daily for all ages (the total daily dose may alternatively be given in 3 divided doses). For oral zinc doses recommended in the management of acute diarrhoea in children, see Administration . Zinc sulfate may also be applied topically, see Uses and .

PubMed Common cold (Latest modification: 07-Dec-2011) Zinc salts have been tried (orally or intranasally) in the treatment of the common cold ( ) with variable results.1-9 A systematic review of randomised studies (conducted in upper-middle and high-income countries, where zinc deficiency is uncommon) found that oral zinc reduced the duration and severity of common cold symptoms when used therapeutically, and that it reduced the incidence of the common cold in healthy children when used prophylactically. However, no firm recommendations could be made regarding the dose, formulation, and duration that should be used.10 (last reviewed 2010-08-23; last modified 2011-12-07) 1. 1. Mossad SB, et al.

Diagnosis and testing A loss of taste acuity is a sign of zinc deficiency (see Taste Disorders, ) and this has been used as a test for the condition: patients who do not immediately perceive a strong flavour on tasting a dilute (typically 0.1 or 0.2%) solution of zinc sulfate are considered likely to benefit from supplementation. However, a study in pregnant women failed to confirm that the ability to taste such a solution was related to zinc deficiency.1 Authors of a small study of Japanese children with short stature evaluated body zinc clearance, and considered those patients with high clearance values but normal serum zinc concentrations to have marginal zinc deficiency.2 (last reviewed 2010-08-23; last modified 2008-07-22) 1. 1.

PubMed Diarrhoea Chronic diarrhoea can be a sign of zinc deficiency, and diarrhoea can lead to excessive zinc losses and zinc deficiency when dietary zinc is inadequate. Zinc supplements have been shown to reduce the incidence, intensity, or duration of acute diarrhoea ( ) in children in developing countries.1-5 Beneficial effects have also been seen with zinc supplementation for persistent diarrhoea.4,5 A WHO report concluded that zinc supplementation is efficacious in significantly reducing the severity and duration of diarrhoea; the type of zinc salt does not appear to influence efficacy, although the best formulation should be determined to minimise adverse effects such as vomiting.6 A further report7 concluded that there was sufficient evidence to recommend the inclusion of zinc as adjunctive therapy to oral rehydration salts in the standard management of both dysenteric and non-dysenteric acute diarrhoea. WHO guidelines on the management of acute diarrhoea recommend 10 to 14 days of oral zinc supplementation at a dose of 10 mg daily for infants under 6 months of age, and 20 mg daily for older children.8 It has been suggested that HIV-infected children should also receive zinc supplementation for diarrhoea, see HIV infection and AIDS, .

Available at: online (accessed 22/07/10) Growth retardation Growth retardation in a group of short Japanese children without endocrine abnormalities was found to be associated with mild to moderate zinc deficiency; supplementation with oral zinc sulfate 5 mg/kg daily over 6 months resulted in an improvement in growth velocity despite unchanged growth hormone production.1 Similarly, supplementation with 10 mg zinc daily for 6 days of each week, for 6 months, increased the growth rate of stunted Ethiopian infants; weight also increased in both stunted and nonstunted children, and the authors commented that these effects were at least partly due to improvements in appetite, and reduced morbidity from infection.2 Results from a meta-analysis of these 2 studies and 31 others indicated that zinc supplementation resulted in a highly significant increase in both linear growth and weight gain of prepubertal children; weight-for- height index was not affected. Significant increases in serum zinc concentrations were also noted with supplementation, but additional studies were considered necessary in order to determine whether mean serum zinc concentration could accurately predict response to supplementation.3 (last reviewed 2010-08-23; last modified 2008-07-22) 1. 1.

PubMed Pneumonia A pooled analysis1 of 10 studies performed in developing countries found that zinc supplementation reduced the incidence of pneumonia in children by 41%. A randomised study in Bangladesh, in 270 children aged 2 to 23 months, found that 20 mg daily of elemental zinc, given orally and adjuvant to standard antimicrobial therapy, accelerated recovery from pneumonia when compared with placebo; children aged 12 months or older resolved their respiratory illness earlier than younger infants.2 Another study in Bangladesh,3 involving 1621 children 2 to 12 months old, found that prophylaxis with 70 mg of oral zinc acetate [about 20 mg of zinc] given weekly reduced the incidence of pneumonia compared with placebo and also reduced subsequent pneumonia-related mortality; a small reduction in the incidence of diarrhoea was also seen. However, a later systematic review4 including 15 randomised controlled studies concluded that on balance the evidence suggested no additional benefit of oral zinc supplementation in children with community-acquired pneumonia who were receiving antimicrobial therapy; there was also no evidence of benefit in preventing pneumonia, and one study had suggested a possible increased incidence and prevalence in children given the supplement.

Although it is unclear to what extent this has clinical consequences, some have suggested that supplementation with modest doses of zinc (less than 45 mg daily) during pregnancy may have beneficial effects on fetal growth and development, and lead to improved pregnancy outcomes.1 A controlled study in Peru found that addition of oral zinc (25 mg of zinc daily as zinc sulfate) to iron and folate supplementation improved fetal bone growth, as measured by femur length.2 A systematic review3 concluded that, while zinc supplementation during pregnancy appears to reduce preterm delivery, there was no convincing evidence that it resulted in other useful benefits. Since the association with preterm birth might reflect poor nutrition, improvement in the overall nutritional status of impoverished populations would be more beneficial than zinc supplementation in isolation.

PubMed Taste disorders Zinc appears to be effective for the treatment of taste disturbances ( ) associated with zinc deficiency but there is insufficient evidence to determine its efficacy for taste dysfunction secondary to conditions that do not involve low serum zinc concentrations.1 Zinc picolinate was found to significantly improve objective measurement of taste when compared with placebo, both in patients with zinc deficiency and in those with idiopathic taste disorders (and normal serum zinc concentrations); there were no differences in subjective assessment of taste.2 A later study3 also found oral zinc gluconate 140 mg daily [about 20 mg of zinc] to be of benefit in idiopathic dysgeusia. In contrast, loss of taste has been reported in some patients using zinc gluconate intranasally, see Polaprezinc ( . ) is also being investigated as a treatment for taste disorders.

Vitamin A deficiency (Latest modification: 07-Nov-2005) It has been proposed1 that the inconsistent effects on morbidity of vitamin A supplementation (see Diarrhoea, under Deficiency States, ) may be due to co-existing micronutrient deficiencies, such as zinc deficiency, that affect the bioavailability of vitamin A. The authors found combined zinc and vitamin A supplementation to be more effective in reducing persistent diarrhoea and dysentery than either zinc or vitamin A alone. There is also some suggestion that zinc may potentiate the effects of vitamin A in the treatment of night blindness,2 but only in those patients already deficient in zinc. A study in Bangladesh3 found that the proportional improvement in vitamin A status in vitamin A-deficient children was larger in those given zinc with vitamin A than in those given vitamin A or zinc alone, suggesting a synergistic effect. Similarly, a study in Indonesia4 of supplementation in pregnant women found that betacarotene with zinc, but not betacarotene or zinc alone, improved vitamin A status in both mothers and infants at 6 months postpartum; the authors suggested that zinc may have a specific role in the conversion of betacarotene to retinol.
