1. What is IVIG Titration?

Intravenous immunoglobulin (IVIG) titration involves calculating the appropriate dose based on patient weight and the prescribed dose per kilogram. This calculation is essential for effective treatment planning.

2. How Does the Calculator Work?

The calculator uses the IVIG dose equation:

Where:

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

Explanation: The equation multiplies the patient's weight by the prescribed dose per kilogram to determine the total IVIG dose needed.

3. Importance of IVIG Dose Calculation

Details: Accurate IVIG dosing is crucial for achieving therapeutic effects while minimizing side effects and ensuring cost-effective treatment.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the typical IVIG dose range?
A: Doses typically range from 0.4 to 2 g/kg depending on the indication, often given over 2-5 days.

Q2: Should ideal or actual body weight be used?
A: For most indications, actual body weight is used, though some protocols adjust for obese patients.

Q3: How is the dose adjusted for renal impairment?
A: Lower doses or slower infusion rates may be needed for patients with renal impairment.

Q4: What are common infusion rates?
A: Rates vary by product but often start at 0.5-1 mg/kg/min, gradually increasing based on tolerance.

Q5: How should the dose be divided?
A: Divided doses are often given over several days (e.g., 1 g/kg/day for 2 days) to improve tolerability.
