1. What is IVIG?

Intravenous immunoglobulin (IVIG) is a blood product prepared from the pooled plasma of thousands of donors. It contains antibodies that help protect against infections and modulate the immune system.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Weight \) — Patient's weight in kilograms
• \( Dose \) — Prescribed dose per kilogram of body weight

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

3. Importance of Accurate IVIG Dosing

Details: Proper dosing is crucial for therapeutic efficacy while minimizing side effects. Dosing varies by indication, ranging from 0.4 g/kg for immune modulation to 2 g/kg for certain autoimmune conditions.

4. Using the Calculator

Tips: Enter patient's weight in kilograms and the prescribed dose in grams per kilogram. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common IVIG dosing ranges?
A: Typical doses range from 0.4-2 g/kg depending on the condition being treated.

Q2: How often is IVIG administered?
A: Frequency varies from single doses to monthly infusions, depending on the indication.

Q3: Are there weight-based dosing limits?
A: Some protocols cap the weight at 100 kg for dose calculations to prevent excessive dosing.

Q4: What factors affect IVIG dosing?
A: Indication, patient's clinical status, and previous response to treatment all influence dosing.

Q5: How is IVIG typically administered?
A: IVIG is given as an intravenous infusion, usually over several hours to minimize side effects.
