This is the same deterministic CDC-protocol logic that ships in the Precision Analgesia iOS app — ported control-for-control from the production taper screen. Every number is computed locally, in the open. Expand the glass box to verify the math yourself.

Educational demonstration only. This demo is not a medical device and must not be used to make clinical decisions. Opioid tapers require individualized clinical judgment and patient monitoring. No data entered here leaves your browser.

Tapering Protocol (CDC 2022)

  • Short-Term (<1yr): uses 2-Phase logic. Phase 1 is Linear (rate% of baseline dose) until 30% remains. Phase 2 is Exponential (rate% of current dose) to prevent withdrawal at low thresholds.
  • Long-Term (≥1yr): uses Slow Taper logic. Pure Exponential reduction (rate% of current dose) performed monthly.
  • Minimum decrement: drops <1 MME alternate Hold / Force (−2 MME) to keep the taper moving.
  • Jump-off: below 10 MME, extend dosing interval; below 5 MME, discontinue.
  • Organ gates: conversion factors adjust — or block entirely — for renal and hepatic impairment.
  • Dispensable rounding: drug doses snap to the nearest practical tablet increment (morphine 7.5 mg · oxycodone 2.5 mg · hydrocodone 2.5 mg · hydromorphone 2 mg · tramadol 25 mg), never below one increment until jump-off. Weeks that round to the same dose merge into a single step.

Reverse Conversion Logic

Drug Dose = Target MME ÷ Factor
Factors used:
  • Oxycodone: 1.5
  • Hydromorphone: 5.0 (CDC 2022)
  • Tramadol: 0.2
