Opioid Refill Guidelines

Critical Refill Restrictions

• The British Journal of Anaesthesia recommends prescribing opioids for 5 days as standard, with an absolute maximum of 7 days for postoperative or acute pain 1, 2, 3, 4
• The British Journal of Anaesthesia advises never prescribing opioids as repeat/refill prescriptions, they must only be documented as acute medications 1
• For chronic non-cancer pain, the JAMA recommends reassessing every 3 months minimum before any continuation 5, 6

Prescribing Algorithm for Refills

• The British Journal of Anaesthesia suggests ruling out surgical complications as the cause of increased pain 2
• The JAMA recommends checking the prescription drug monitoring program (PDMP) for patterns of doctor shopping or concurrent prescriptions 1, 5
• The JAMA advises performing urine drug testing (UDT) to identify non-adherence or illicit drug use 5

Refill Specifications

• The British Journal of Anaesthesia recommends using immediate-release formulations only, avoiding long-acting or extended-release opioids without specialist consultation 1, 2, 3, 8, 5, 4
• The JAMA suggests starting with the lowest effective dose, considering up to 40 morphine milligram equivalents (MME) as low dose, 41-90 MME as moderate, >91 MME as high dose 5

Mandatory Patient Education

• The British Journal of Anaesthesia recommends providing education on safe self-administration, weaning protocols, and disposal of unused medications 1, 2, 3, 4
• The British Journal of Anaesthesia advises educating patients on the dangers of driving or operating machinery while taking opioids 1, 2, 3, 4

Adherence Monitoring

• The JAMA recommends checking PDMP at each refill consideration 5
• The JAMA suggests performing UDT from initiation and throughout therapy 5
• The British Journal of Anaesthesia advises monitoring sedation scores and respiratory rate to detect opioid-induced ventilatory impairment 2, 4

Critical Pitfalls to Avoid

• The British Journal of Anaesthesia warns against adding postoperative opioids to repeat prescription templates, as this can lead to inadvertent chronic therapy 1, 3, 4
• The British Journal of Anaesthesia recommends avoiding prescribing beyond 7 days without documented medical necessity and specialist input 1, 2, 3, 4
• The JAMA advises against combining opioids with benzodiazepines without careful justification 5

Discontinuation and Weaning

• The British Journal of Anaesthesia recommends following a reverse analgesic ladder when analgesic requirements decrease, starting with weaning opioids, then stopping NSAIDs, and finally stopping paracetamol (acetaminophen) 1, 2, 3, 4
• The British Journal of Anaesthesia suggests that patients must return excess opioids to community or hospital pharmacy, never disposing at home 1, 3, 4
