1. What is Rituximab Dosing by Body Surface Area?

Definition: This calculator determines the appropriate dose of rituximab based on the patient's body surface area (BSA).

Purpose: It helps healthcare professionals calculate the correct medication dosage for treatments involving rituximab.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Dose} \) — Rituximab dose in milligrams (mg)
• \( \text{BSA} \) — Body Surface Area in square meters (m²)

Explanation: The standard rituximab dose is 375 mg per square meter of body surface area.

3. Importance of Accurate Rituximab Dosing

Details: Proper dosing ensures therapeutic effectiveness while minimizing potential side effects and toxicity.

4. Using the Calculator

Tips: Enter the patient's body surface area in square meters. The BSA value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard rituximab dose?
A: The standard dose is 375 mg/m², though some protocols may vary.

Q2: How is BSA typically calculated?
A: BSA is commonly calculated using the Mosteller formula: √(height in cm × weight in kg / 3600).

Q3: Are there maximum dose limits?
A: Some protocols may specify maximum doses; consult treatment guidelines.

Q4: How often is this dose administered?
A: Frequency depends on the treatment protocol, often weekly for 4-8 doses.

Q5: Can this calculator be used for pediatric patients?
A: Yes, but pediatric dosing should always be verified with a specialist.
