1. What is IVIG Dose Calculation?

IVIG (Intravenous Immunoglobulin) dose calculation is based on patient weight and the prescribed dose per kilogram. This ensures accurate dosing for immunomodulation or replacement therapy.

2. How Does the Calculator Work?

The calculator uses the IVIG dose equation:

Where:

• \( Weight \) — Patient weight in kilograms
• \( Dose \) — Prescribed dose in grams per kilogram

Explanation: The equation calculates the total IVIG dose by multiplying the patient's weight by the prescribed dose per kilogram.

3. Importance of Accurate IVIG Dosing

Details: Precise IVIG dosing is critical for therapeutic efficacy while minimizing side effects. Dosing varies based on indication (e.g., 0.4-1 g/kg for immunomodulation, 0.3-0.6 g/kg for replacement).

4. Using the Calculator

Tips: Enter weight in kilograms and dose in g/kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical IVIG dose range?
A: Common ranges are 0.4-1 g/kg for immunomodulation and 0.3-0.6 g/kg for replacement therapy, but always follow prescribing guidelines.

Q2: How often is IVIG administered?
A: Frequency varies by indication - from daily for acute conditions to monthly for chronic conditions.

Q3: Should ideal or actual body weight be used?
A: This depends on the protocol - some use actual weight, others use adjusted body weight for obese patients.

Q4: Are there different calculations for different IVIG products?
A: While the basic calculation is the same, different products may have specific concentration or infusion rate considerations.

Q5: How is the dose adjusted for renal impairment?
A: Lower doses or slower infusion rates may be needed for patients with renal impairment to prevent complications.
