Common errors occur due to confusion between:- Oramorph ® liquid and OxyNorm ® liquid- Morphine tablets and Morphine MR tablets- OxyContin ® and OxyNorm ®- Prescribe MR products by brand.• Dose prescribed is clear:E.g. 'Methadone 40 ml daily' does not indicate the dose to be given.- On the kardex prescribe:'Methadone 40 mg daily'- On discharge prescription write as:'Methadone oral solution 1 mg/ml, 40 ml daily'DATIX reports show a number of incidents where millilitres and milligrams have been confusedin liquid preparations. For Oramorph ® 10 mg/5 ml this can result in patients receiving double theintended dose.Page 6
