1. What is IVIG Infusion Rate?

The IVIG (Intravenous Immunoglobulin) infusion rate determines how quickly the medication should be administered. Proper rate calculation is essential to prevent adverse reactions and ensure therapeutic effectiveness.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Rate \) — Infusion rate in mL/hour
• \( Dose \) — Total volume of IVIG to be infused in mL
• \( Time \) — Total infusion time in hours

Explanation: This calculation provides the milliliter-per-hour rate at which the IVIG should be administered.

3. Importance of Proper Infusion Rates

Details: IVIG must be infused at appropriate rates to minimize side effects like headaches, flushing, and more serious reactions while ensuring the full dose is delivered as prescribed.

4. Using the Calculator

Tips: Enter the total dose in milliliters and the desired infusion time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical IVIG infusion rate?
A: Rates vary but often start at 0.5-1 mg/kg/min (or 30-60 mL/hr) initially, then gradually increased based on tolerance.

Q2: Why are infusion rates important?
A: Too rapid infusion increases risk of adverse reactions, while too slow may delay therapeutic effect and prolong treatment.

Q3: Can I use this for subcutaneous IG?
A: No, this calculator is specifically for intravenous administration rates.

Q4: How does concentration affect the rate?
A: Higher concentration products may require slower initial rates. Always follow manufacturer guidelines.

Q5: What if the patient has reactions?
A: The rate should be reduced or temporarily stopped for significant adverse reactions, then resumed at a slower rate if appropriate.
