MME/MED Calc

Incomplete Cross-Tolerance

Calculated equivalencies are mathematical constructs. Due to incomplete cross-tolerance, the calculated target dose MUST ALWAYS be reduced by 25-50% to prevent fatal overdose during rotation.

0% (High Risk)25% (Standard)50% (Conservative)75%

Calculated Total MME/Day

15.0 MME

Safe Target Dose (24h)

11.3 mg

Reflects 25% algorithmic reduction from raw mathematical equivalent (15.0 mg).
