Copper deficiency treatment via IV copper is dosed at what range per day for 6 days?

• A. 1-2 mg/d for 3 days
• B. 2-4 mg/d for 6 days
• C. 4-6 mg/d for 8 days
• D. 6-8 mg/d for 5 days

Answer: (B)

Replenishing copper stores through IV therapy uses a modest daily amount over several days to restore copper-dependent functions and correct deficiency symptoms. The standard approach is to give 2-4 mg of elemental copper each day for six days. This range provides enough copper to replete stores and improve blood abnormalities without markedly increasing toxicity risk, and the six-day course fits typical repletion timelines before transitioning to oral maintenance. Shorter, lower dosing may fail to restore levels, while higher daily amounts or longer courses aren’t generally necessary and can raise toxicity risk. After repletion, continue with oral copper and monitor levels as needed.
