Octagam 10 Infusion Rate Calculator

Clinical Titration Tool for Healthcare Professionals

Quick Presets (Standard Titration):

function setRate(val) { document.getElementById('titrationRate').value = val; } function calculateInfusion() { var weight = parseFloat(document.getElementById('patientWeight').value); var mgRate = parseFloat(document.getElementById('titrationRate').value); if (isNaN(weight) || isNaN(mgRate) || weight <= 0 || mgRate <= 0) { alert("Please enter valid numbers for weight and titration rate."); return; } // Octagam 10% contains 100 mg/mL // Formula: (Weight kg * Rate mg/kg/min) = Total mg/min // (Total mg/min / 100 mg/mL) = mL/min // mL/min * 60 = mL/hr var mgPerMin = weight * mgRate; var mlPerMin = mgPerMin / 100; var mlPerHr = mlPerMin * 60; document.getElementById('mlHrResult').innerText = mlPerHr.toFixed(2); document.getElementById('mgMinResult').innerText = mgPerMin.toFixed(2); document.getElementById('results').style.display = 'block'; }

Understanding Octagam 10% Infusion Rates

Octagam 10% [Immune Globulin Intravenous (Human)] is a high-concentration 10% liquid preparation of highly purified immunoglobulin G (IgG). Accurate infusion rate calculation is critical for patient safety, particularly during the initial titration phase to mitigate potential adverse reactions.

Standard Titration Protocol

The concentration of Octagam 10 is 100 mg per mL. Clinical guidelines typically recommend the following titration schedule for patients with Primary Humoral Immunodeficiency (PI):

Stage	Rate (mg/kg/min)	Duration
Initial Rate	1.0 mg/kg/min	First 30 minutes
Maintenance	Up to 8.0 mg/kg/min	As tolerated

How to Calculate mL/hr for Octagam 10%

To convert the prescribed dosage from mg/kg/min to the pump setting (mL/hr), use the following clinical formula:

Rate (mL/hr) = [Weight (kg) × Dose (mg/kg/min) × 60] / 100

Example Calculation

For a patient weighing 80 kg, starting at the initial rate of 1.0 mg/kg/min:

• Step 1: Calculate mg per minute: 80 kg × 1.0 mg/kg/min = 80 mg/min.
• Step 2: Convert mg/min to mL/min: 80 mg/min ÷ 100 mg/mL = 0.8 mL/min.
• Step 3: Convert to hourly rate: 0.8 mL/min × 60 min = 48 mL/hr.

Important Clinical Considerations

• Hydration: Ensure patients are adequately hydrated prior to starting the infusion.
• Renal Function: For patients at risk of renal dysfunction, infuse at the minimum rate practicable.
• Monitoring: Assess vital signs throughout the infusion, especially when increasing the rate.
• Maximum Rate: Do not exceed the maximum infusion rate of 0.12 mL/kg/min (12 mg/kg/min) for PI patients as specified in the product labeling.
