Renal Dose Adjustment

• Renal impairment: Dose adjustments not defined

Hepatic Dose Adjustment

• Hepatic impairment: Dose adjustments not defined

• Therapy is not recommended for the initial therapy of symptomatic patients because of the delay required for zinc-induced increase in enterocytic metallothionein and blockade of copper uptake
• Symptomatic patients should be treated initially, using chelating agents
• During initial therapy, neurological deterioration may occur as stores of copper are mobilized
• Once initial therapy has been completed, and the patient is clinically stable, maintenance treatment with zinc acetate can be considered
• Patients should be monitored primarily by assessment of existing signs and symptoms of Wilson’s disease and 24-hour urine copper
• Neuropsychiatric evaluations including speech as well as liver function tests including bilirubin and aminotransferases, should be done as appropriate
• The clinician should be aware that urinary copper levels are usually increased with chelation therapy such as penicillamine or trientine

Pregnancy Category:A

Breastfeeding: Zinc does appear in breast milk and zinc-induced copper deficiency in the nursing baby may occur. Therefore, it is recommended that women on zinc therapy not nurse their babies.
