Terms and conditions
This opioid analgesic equivalence site is designed as an educational tool. Use of this site in clinical scenarios needs to take into account the specific clinical condition of the patient: e.g. age, body mass, liver & renal function, current medications, psychology and desired patient outcomes.
This site has been developed to calculate the total oral morphine equivalent daily dose and not to support opioid rotation or switching from one opioid to another. Methadone, fentanyl lozenges and neuraxial opioids are not included in this site due to their complex and variable pharmacokinetics.
By using this site you acknowledge and agree to use your own independent judgement in relation to treating patients and to review the Product Information of a medication before prescribing that medication. You also agree to accept the terms and conditions and privacy policy of this site before use.
