1. What is a Global RPH MME Calculator?

Definition: This calculator determines Morphine Milligram Equivalents (MME) by converting opioid dosages to an equivalent amount of morphine.

Purpose: It helps healthcare professionals standardize opioid dose comparisons for safer prescribing and monitoring.

2. How Does the MME Calculator Work?

The calculator uses the formula:

Where:

• \( \text{MME} \) — Morphine Milligram Equivalent (mg/day)
• \( \text{Dose} \) — Actual opioid dose (mg/day)
• \( \text{Factor} \) — Conversion factor specific to the opioid

Explanation: Multiply the opioid dose by its conversion factor to get the equivalent morphine dose.

3. Importance of MME Calculation

Details: MME calculations help assess opioid overdose risk, guide prescribing decisions, and monitor patients on chronic opioid therapy.

4. Using the Calculator

Tips: Enter the opioid dose in mg/day and the appropriate conversion factor (default 1.0 for morphine). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical conversion factors?
A: Examples: Morphine=1, Oxycodone=1.5, Hydrocodone=1, Hydromorphone=4, Fentanyl patches=7.5 (varies by route).

Q2: Why is MME important?
A: MME helps standardize comparisons between different opioids and assess overdose risk (≥50 MME/day increases risk).

Q3: Where can I find conversion factors?
A: CDC guidelines and pharmacology references provide conversion tables for different opioids.

Q4: Does this account for patient factors?
A: No, always consider individual patient factors like tolerance, age, and comorbidities.

Q5: How do I use MME in practice?
A: Use to track total opioid exposure, taper plans, and when switching between opioids.
