Active Ingredient: Cholecalciferol (Vitamin D3) 200,000 IU/ml.
What it does: It is a highly concentrated form of Vitamin D3 that rapidly restores depleted Vitamin D stores, which is vital for calcium absorption, bone mineralization, and immune support.
Prescribed for: Severe Vitamin D deficiency, osteomalacia (softening of the bones), nutritional rickets, and as a supportive therapy for osteoporosis.
Standard Regimen: The dose and frequency (typically once every few weeks or months) are highly individualized based on your initial blood levels of 25-hydroxyvitamin D.
Important Rules: This medication is for intramuscular (IM) injection only and must be administered by a qualified healthcare professional. Do not inject intravenously.
Monitoring Warning: Your doctor will likely order routine blood tests to monitor calcium, phosphate, and Vitamin D levels to prevent accidental toxicity (hypervitaminosis D).
Side effects are rare when used in recommended doses.
Toxicity/Overdose Signs: If blood calcium levels get too high (hypercalcemia), you may experience nausea, vomiting, extreme thirst, frequent urination, severe constipation, muscle weakness, or confusion.
Long-term risk: Prolonged excessive levels can lead to kidney stones or kidney impairment.
