Vitamin D3 60,000 IU weekly can sometimes cause side effects if levels become high. Excessive thirst and sleep disturbance may suggest high
calcium levels (hypercalcemia) or that the dose is not currently needed. These symptoms are not normal and should be evaluated.
Next Steps
• Stop
Vitamin D3 temporarily until evaluated
• Get blood tests: Serum 25-OH
Vitamin D, Serum
Calcium,
Creatinine, and
Fasting Blood Sugar
• Consult a doctor with reports before restarting or adjusting the dose
• If vitamin D is still needed, dose may be reduced (e.g., monthly or lower daily dose)
Health Tips
• Do not continue high-dose
vitamin D without monitoring
• Drink adequate water
• Seek urgent care if there is severe thirst, vomiting, confusion, frequent urination, or palpitations
High-dose vitamin D should always be taken for a defined duration with follow-up testing.
