Zinc Chloride in Plastic Container

Zinc 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition. Administration helps to maintain zinc serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

None known.

Direct intramuscular or intravenous injection of Zinc 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation. Severe kidney disease may make it necessary to reduce or omit chromium and zinc doses because these elements are primarily eliminated in the urine. Copper Deficiency Several post-marketing cases have reported that zinc products taken over extended periods of time (i.e., months to years) may result in copper deficiency.

The cases reported the following complications of copper deficiency: anemia, granulocytopenia, leukopenia, neutropenia, pancytopenia, thrombocytopenia, and myeloneuropathy. If a patient develops signs and/or symptoms of copper deficiency during treatment with zinc chloride, interrupt zinc treatment and check zinc and copper levels. Consider supplemental copper administration to treat copper deficiency and monitor zinc levels.

Aluminum Toxicity This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum. Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity.

Tissue loading may occur at even lower rates of administration.
