CAUTION: This calculator should NOT be used to determine doses when converting a patient from one opioid to another. This is especially important for fentanyl and methadone conversions. Equianalgesic dose ratios are only approximations and do not account for genetic factors, incomplete cross-tolerance, and pharmacokinetics.

† There are special considerations for calculating Methadone (Methadose, Dolophine) MED, please view the following page for conversion factors and references: Methadone Conversion Factors
