1. What is an Opiate Conversion Calculator?

Definition: This calculator estimates the equivalent dose of one opioid medication compared to another based on conversion ratios.

Purpose: It helps healthcare professionals safely convert between different opioid medications while maintaining equivalent analgesic effects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Equivalent_dose — Dose of target opioid (mg)
• dose — Current opioid dose (mg)
• conversion_ratio — Ratio between opioids (dimensionless)

Explanation: The current dose is multiplied by an evidence-based conversion ratio to determine the equivalent dose of another opioid.

3. Importance of Accurate Opiate Conversion

Details: Proper conversion prevents under- or over-dosing when switching opioids, which is critical for patient safety and effective pain management.

4. Using the Calculator

Tips: Enter the current opioid dose in mg and the appropriate conversion ratio. All values must be > 0. Always consult conversion charts for specific ratios.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find conversion ratios?
A: Refer to evidence-based opioid conversion charts from reputable sources like Global RPH or clinical guidelines.

Q2: Is this calculator suitable for all opioids?
A: It works for most common opioids, but some (like methadone or fentanyl) require special consideration due to non-linear conversions.

Q3: Why might actual doses differ from calculations?
A: Individual patient factors, incomplete cross-tolerance, and drug-specific properties may require dose adjustments.

Q4: Should I use this for chronic pain conversions?
A: For chronic pain, typically reduce calculated dose by 25-50% to account for incomplete cross-tolerance.

Q5: Does this account for route of administration?
A: No, you must use appropriate conversion ratios for different routes (IV, oral, transdermal, etc.).
