MORPHINE(Opium Tincture Deodorized)
Contraindicated

The combination significantly increases the risk of severe respiratory depression, profound sedation, coma, and death. Patients may experience decreased level of consciousness, hypoventilation, hypoxia, and hypotension. Psychomotor impairment and an increased risk of falls are also common.

Mechanism

Morphine, an opioid agonist, primarily acts on mu-opioid receptors in the central nervous system (CNS) to produce analgesia and respiratory depression. Lorazepam, a benzodiazepine, enhances the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) at GABA-A receptors. The co-administration of these two CNS depressants leads to additive or synergistic depression of the CNS, particularly affecting respiratory drive.

Clinical Management

Concomitant use of opioids and benzodiazepines should generally be avoided due to the high risk of severe adverse outcomes, as highlighted by an FDA Black Box Warning. If co-prescription is absolutely necessary and no alternatives are available, use the lowest effective doses and shortest possible duration, monitor patients closely for respiratory depression and sedation, and counsel them on the risks. Naloxone should be readily available for opioid overdose reversal.

TRAMADOL HYDROCHLORIDE(TRAMADOL HYDROCHLORIDE)
Contraindicated

This combination significantly increases the risk of severe respiratory depression, profound sedation, coma, and death. Patients may experience decreased respiratory rate, shallow breathing, hypoxemia, unresponsiveness, and difficulty arousing.

Mechanism

Both tramadol, an opioid analgesic, and lorazepam, a benzodiazepine, are central nervous system (CNS) depressants. Their co-administration leads to an additive depressant effect on the CNS, particularly on the respiratory drive and level of consciousness, by enhancing GABAergic neurotransmission and opioid receptor agonism, respectively.

Clinical Management

Concomitant use of opioids and benzodiazepines should generally be avoided due to the FDA Black Box Warning. If co-administration is absolutely necessary and no alternatives exist, use the lowest effective doses for the shortest possible duration, closely monitor patients for respiratory depression and sedation, and educate patients and caregivers on the risks. Naloxone should be readily available.

OXYMORPHONE HYDROCHLORIDE(Oxymorphone Hydrochloride)
Contraindicated

Concomitant use can lead to severe and potentially fatal respiratory depression, profound sedation, coma, and death. Patients may exhibit decreased level of consciousness, hypoventilation, bradycardia, hypotension, and miosis. The risk is heightened in opioid-naïve individuals, elderly patients, or those with underlying respiratory compromise.

Mechanism

Oxymorphone, a mu-opioid receptor agonist, and lorazepam, a gamma-aminobutyric acid (GABA)-A receptor positive allosteric modulator, both cause central nervous system (CNS) depression. Their co-administration leads to additive and synergistic CNS depressant effects, primarily by enhancing the inhibitory neurotransmission in the brainstem respiratory centers and other CNS areas. This leads to profound depression of ventilatory drive and reduced arousal.

Clinical Management

Concomitant use of opioids and benzodiazepines is contraindicated due to the high risk of severe adverse outcomes. If co-administration is unavoidable and no alternative treatment options are adequate, prescribers must limit dosages and duration to the minimum necessary and monitor patients closely for signs of respiratory depression and sedation. Naloxone should be readily available, and patients/caregivers must be educated on the risks and symptoms.

BUPRENORPHINE(BUPRENORPHINE)
Major

The primary clinical effects include profound sedation, respiratory depression, coma, and potentially death. Patients may exhibit reduced respiratory rate, shallow breathing, hypoxemia, and decreased level of consciousness. Other effects can include hypotension, bradycardia, and psychomotor impairment.

Mechanism

Buprenorphine, a partial opioid agonist, and lorazepam, a benzodiazepine, both exert central nervous system (CNS) depressant effects. Their co-administration leads to an additive and synergistic depression of the CNS, primarily by enhancing gamma-aminobutyric acid (GABA) activity (benzodiazepines) and opioid receptor agonism (buprenorphine). This combined effect significantly impairs respiratory drive and consciousness.

Clinical Management

Co-prescription of buprenorphine and lorazepam should generally be avoided due to the high risk of severe adverse outcomes, as highlighted by the FDA Black Box Warning. If co-administration is deemed absolutely necessary and no alternatives exist, it must be done with extreme caution, initiating with the lowest effective doses of both medications and titrating slowly while closely monitoring for signs of respiratory depression and sedation. Patients and caregivers must be educated about the risks and symptoms of overdose.

FENTANYL(FENTANYL)
Major

This combination significantly increases the risk of severe respiratory depression, profound sedation, coma, and death. Patients may experience decreased level of consciousness, hypoventilation, hypoxia, and hypotension. These effects can be life-threatening if not promptly recognized and managed.

Mechanism

Fentanyl, an opioid agonist, primarily acts on mu-opioid receptors in the central nervous system (CNS) to produce analgesia and respiratory depression. Lorazepam, a benzodiazepine, enhances the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) at GABA-A receptors. The co-administration of these CNS depressants results in synergistic depression of respiratory drive and CNS activity.

Clinical Management

Avoid concomitant use of fentanyl and lorazepam whenever possible. If co-administration is unavoidable, use the lowest effective doses and shortest possible duration, and closely monitor patients for signs of respiratory depression and sedation. Ensure naloxone is readily available, and educate patients and caregivers about the risks and symptoms requiring immediate medical attention.

OXYCODONE(Oxycodone Hydrochloride)
Major

The combination significantly increases the risk of severe respiratory depression, which can lead to hypoxemia, apnea, and death. Patients may experience profound sedation, somnolence, dizziness, and impaired psychomotor function. Other serious effects include coma and hypotension.

Mechanism

Oxycodone, an opioid agonist, primarily acts on mu-opioid receptors in the central nervous system (CNS), leading to dose-dependent CNS depression, including respiratory depression and sedation. Lorazepam, a benzodiazepine, enhances the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) at GABA-A receptors, also causing CNS depression, sedation, and respiratory depression. The concurrent use of these two classes of drugs results in an additive and synergistic CNS depressant effect, profoundly increasing the risk of severe adverse outcomes.

Clinical Management

Co-prescription of opioids and benzodiazepines should generally be avoided due to the high risk of severe adverse events. If co-administration is absolutely necessary, it should be done with extreme caution, using the lowest effective doses for the shortest possible duration, and only if alternative treatments are inadequate. Patients and caregivers must be educated about the risks, including signs of respiratory depression and sedation, and instructed to seek immediate medical attention if these occur. Close monitoring for respiratory depression and altered mental status is crucial.

CODEINE SULFATE(Codeine sulfate)
Major

The co-administration of codeine and lorazepam can lead to profound sedation, respiratory depression, coma, and death. Patients may experience decreased level of consciousness, hypoventilation, apnea, and hypotension. These effects can be life-threatening and require immediate medical intervention.

Mechanism

Codeine is an opioid analgesic that primarily acts as a mu-opioid receptor agonist, leading to central nervous system (CNS) depression, including respiratory depression. Lorazepam is a benzodiazepine that enhances the effect of gamma-aminobutyric acid (GABA) at the GABA-A receptor, resulting in further CNS depression. The combined CNS depressant effects are synergistic, significantly increasing the risk of adverse outcomes.

Clinical Management

Avoid concomitant use of codeine and lorazepam whenever possible. If co-prescription is unavoidable, use the lowest effective doses and for the shortest duration necessary, carefully titrating and monitoring for signs of respiratory depression and sedation. Educate patients and caregivers about the risks and symptoms of CNS depression and respiratory depression, advising them to seek immediate medical attention if these occur.

METHADONE(Methadone Hydrochloride)
Major

The concurrent use of methadone and lorazepam significantly increases the risk of severe respiratory depression, profound sedation, coma, and death. Patients may experience decreased respiratory rate, shallow breathing, hypoxemia, and difficulty arousing. Other effects include dizziness, confusion, psychomotor impairment, and hypotension.

Mechanism

Both methadone, an opioid agonist, and lorazepam, a benzodiazepine, are central nervous system (CNS) depressants. Their co-administration leads to an additive and synergistic depressant effect on the CNS, particularly on the respiratory drive and level of consciousness. This occurs through their respective actions on opioid receptors and GABA-A receptors, leading to enhanced inhibitory neurotransmission.

Clinical Management

Avoid concomitant prescribing of methadone and lorazepam whenever possible. If co-prescription is unavoidable, use the lowest effective doses for the shortest duration possible, and closely monitor patients for signs of respiratory depression and sedation. Educate patients and caregivers about the risks, and provide naloxone if appropriate. Consider non-benzodiazepine alternatives for anxiety or insomnia.

HYDROMORPHONE HYDROCHLORIDE(Hydromorphone Hydrochloride)
Major

The concurrent use of hydromorphone and lorazepam significantly increases the risk of severe respiratory depression, profound sedation, hypotension, psychomotor impairment, coma, and death. Patients may exhibit decreased level of consciousness, bradycardia, pinpoint pupils, and hypoventilation. The FDA has issued a Black Box Warning highlighting these life-threatening risks.

Mechanism

Hydromorphone, an opioid agonist, primarily acts on mu-opioid receptors in the central nervous system (CNS) to produce analgesia, sedation, and respiratory depression. Lorazepam, a benzodiazepine, enhances the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) at GABA-A receptors, leading to CNS depression. The co-administration of these two CNS depressants results in an additive and synergistic depressant effect on the brainstem respiratory centers and overall CNS activity.

Clinical Management

Avoid concomitant use of hydromorphone and lorazepam whenever possible. If co-administration is unavoidable, prescribe the lowest effective doses for the shortest duration possible, and closely monitor patients for signs of respiratory depression and sedation. Educate patients and caregivers on the risks and symptoms of CNS depression, and consider prescribing naloxone for at-risk patients.

TAPENTADOL HYDROCHLORIDE(Tapentadol Hydrochloride)
Major

Concomitant use significantly increases the risk of severe respiratory depression, profound sedation, coma, and death. Patients may exhibit decreased level of consciousness, bradycardia, hypotension, and hypoxemia. This interaction can also impair psychomotor function, increasing the risk of falls and accidents.

Mechanism

Both tapentadol (an opioid analgesic with norepinephrine reuptake inhibition) and lorazepam (a benzodiazepine) are central nervous system (CNS) depressants. Tapentadol's opioid activity primarily agonizes mu-opioid receptors, while lorazepam enhances the effect of the inhibitory neurotransmitter GABA at GABA-A receptors. The additive CNS depressant effects of these two drug classes lead to profound respiratory depression, sedation, and hypotension.

Clinical Management

Avoid concomitant use of tapentadol and lorazepam whenever possible due to the high risk of severe adverse outcomes, as highlighted by an FDA Black Box Warning. If co-prescription is absolutely necessary, use the lowest effective doses for the shortest possible duration, and closely monitor patients for signs of respiratory depression, sedation, and hypotension. Educate patients and caregivers about the risks and symptoms, and consider prescribing naloxone if appropriate.
