Dosage Form
Injection (sterile solution) — 1 ml ampoule containing 5 mg cholecalciferol (Vitamin D3)
Uses (Indications)
Sunny D Insta is used for:
-
Correction of Vitamin D deficiency, especially in patients who cannot take oral supplements
-
Cases of malabsorption, chronic liver disease, or when oral uptake is compromised
-
Support for bone health, calcium metabolism, and maintenance of normal vitamin D levels
Dosage
-
The dose is high (5 mg / 200,000 IU) in a single ampoule; the exact regimen or frequency is determined by the physician based on the patient’s deficiency severity, baseline vitamin D levels, and risk factors.
-
Such high-dose injections are typically not repeated frequently; follow monitoring guidelines (e.g. checking serum 25(OH)D, calcium) before further dosing.
In Case of Overdose
-
Excessive vitamin D can lead to hypercalcemia — symptoms may include nausea, vomiting, weakness, frequent urination, kidney stones, confusion.
-
Management: Stop supplementation, restrict dietary calcium, hydrate, monitor and treat hypercalcemia under medical supervision.
Missed Dose
-
In a clinical setting, missing an injection should be addressed by the treating physician.
-
Do not self-administer or double the dose to compensate.
How To Use / Administration
-
Administer via intramuscular (IM) injection (often recommended for depot effect) or as per manufacturer instructions.
-
Use aseptic technique.
-
Monitor patients during and after injection for adverse events, especially in cases of underlying conditions (kidney, calcium metabolism).
When Not to Use (Contraindications)
