Concerns related to adverse effects:
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Constipation: May cause constipation which may be problematic in patients with unstable angina and patients post-myocardial infarction. Consider preventive measures (eg, stool softener, increased fiber) to reduce the potential for constipation.
• Hypotension: May cause severe hypotension (including orthostasis and syncope); risk is increased in patients with reduced blood volume or taking concurrent CNS depressants (eg, phenothiazines, general anesthetics). Avoid use in patients with circulatory shock.
• Respiratory depression: [Canadian Boxed Warning]: Serious, life-threatening, or fatal respiratory depression may occur. Infants exposed in utero or through breast milk are at risk of life-threatening respiratory depression upon delivery or when nursed. Patients should be monitored for respiratory depression, especially during initiation or following a dose increase. Further, instruct patients of hazards related to taking opioids, including fatal overdose. Patients and caregivers should be educated on how to recognize respiratory depression and the importance of getting emergency assistance immediately in the event of known or suspected overdose.
• Serotonin syndrome: May occur with concomitant use of serotonergic agents (eg, selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, triptans, tricyclic antidepressants), lithium, St John's wort, agents that impair metabolism of serotonin (eg, monoamine oxidase inhibitors), or agents that impair metabolism of tramadol (eg, CYP2D6 and 3A4 inhibitors).
Disease related concerns:
• Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenocortical insufficiency: Use with caution in patients with adrenocortical insufficiency, including Addison disease; dose adjustment may be required. Long-term opioid use may cause secondary hypogonadism, which may lead to mood disorders and osteoporosis (Brennan 2013).
• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture; dose adjustment may be required.
• Psychosis: Use with caution in patients with toxic psychosis.
• Respiratory disease: Use with caution and monitor for respiratory depression in patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression, particularly when initiating and titrating therapy; critical respiratory depression may occur, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Alcohol: [Canadian Boxed Warning]: The co-ingestion of alcohol should be avoided as it may result in dangerous additive effects, causing serious injury or death.
• Benzodiazepines or other CNS depressants: [Canadian Boxed Warning]: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid use of opioid cough medications in patients taking benzodiazepines, other CNS depressants, or alcohol. Reserve concomitant prescribing of normethadone/hydroxyephedrine and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosage and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation. Consider prescribing naloxone or nalmefene for emergency treatment of opioid overdose in patients taking benzodiazepines or other CNS depressants concomitantly with opioids.
Special populations:
• Neonates: Neonatal withdrawal syndrome: [Canadian Boxed Warning]: Prolonged maternal use of opioids during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening.
Other warnings/precautions:
• Accidental exposure: [Canadian Boxed Warning]: Accidental exposure, especially by children, can result in a fatal overdose of normethadone.
• Limitations of Use: [Canadian Boxed Warning]: Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the risks of overdose and death with immediate-release opioid formulations, normethadone and hydroxyephedrine should only be used in patients for whom alternative non-opioid therapies are ineffective, not tolerated, or would be otherwise inadequate to provide appropriate cough management. Underlying cause of cough should be determined prior to prescribing.
• Naloxone/Nalmefene access: Discuss the availability of naloxone or nalmefene with all patients who are prescribed opioid analgesics, as well as their caregivers, and consider prescribing it to patients who are at increased risk of opioid overdose. These include patients who are also taking benzodiazepines or other CNS depressants, have an opioid use disorder (OUD) (current or history of), or have experienced a previous opioid overdose. Additionally, health care providers should consider prescribing naloxone or nalmefene to patients prescribed medications to treat OUD; patients at risk of opioid overdose even if they are not taking an opioid analgesic or medication to treat OUD; and patients taking opioids, including methadone or buprenorphine for OUD, if they have household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose. Inform patients and caregivers on options for obtaining naloxone or nalmefene (eg, by prescription, directly from a pharmacist, a community-based program) as permitted by state dispensing and prescribing guidelines. Educate patients and caregivers on how to recognize respiratory depression, proper administration of naloxone or nalmefene, and getting emergency help.
• Substance use disorder/abuse/misuse: [Canadian Boxed Warning]: Use poses risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Each patient's risk should be assessed prior to prescribing and all patients should be monitored regularly for development of these behaviors or conditions . Store securely to avoid theft or misuse.
