Interactions between your drugs

Major

fentaNYL dezocine

Applies to: Lazanda (fentanyl) and dezocine

GENERALLY AVOID: Concomitant use of opioids with other central nervous system (CNS) depressants including mixed agonist-antagonist or partial agonist opioids may result in profound sedation, respiratory depression, coma, and death. The risk of hypotension may also be increased. On the other hand, mixed agonist-antagonist or partial agonist opioids can reduce the pharmacologic effects of other opioid agonists. Reduced efficacy or withdrawal symptoms may occur in patients maintained on their opioid regimen following the addition of a mixed agonist-antagonist or partial agonist opioid.

MANAGEMENT: The use of opioids in conjunction with other CNS depressants including mixed agonist-antagonist or partial agonist opioids should generally be avoided unless alternative treatment options are inadequate. If coadministration is necessary (e.g., when initiating a switch from one opioid to the other), the dosage and duration of each drug should be limited to the minimum required to achieve desired clinical effect, and patients should be closely monitored for signs and symptoms of CNS and respiratory depression. Additional caution is advisable when a mixed agonist-antagonist or partial agonist opioid is added to an existing opioid regimen, as there may be an increased risk of withdrawal symptoms (e.g., restlessness, insomnia, sweating, lacrimation, or rhinorrhea) following initiation of the mixed agonist-antagonist or partial agonist opioid. A dosage adjustment for one or both drugs may be required.

Drug and food interactions

Major

fentaNYL food

Applies to: Lazanda (fentanyl)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including fentanyl. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

GENERALLY AVOID: Consumption of grapefruit juice during treatment with oral transmucosal formulations of fentanyl may result in increased plasma concentrations of fentanyl, which is primarily metabolized by CYP450 3A4 isoenzyme in the liver and intestine. Certain compounds present in grapefruit are known to inhibit CYP450 3A4 and may increase the bioavailability of swallowed fentanyl (reportedly up to 75% of a dose) and/or decrease its systemic clearance. The clinical significance is unknown. In 12 healthy volunteers, consumption of 250 mL regular-strength grapefruit juice the night before and 100 mL double-strength grapefruit juice one hour before administration of oral transmucosal fentanyl citrate (600 or 800 mcg lozenge) did not significantly affect fentanyl pharmacokinetics, overall extent of fentanyl-induced miosis (miosis AUC), or subjective self-assessment of various clinical effects compared to control. However, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability. The possibility of significant interaction in some patients should be considered.

MANAGEMENT: Patients should not consume alcoholic beverages or use drug products that contain alcohol during treatment with fentanyl. Any history of alcohol or illicit drug use should be considered when prescribing fentanyl, and therapy initiated at a lower dosage if necessary. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Due to a high degree of interpatient variability with respect to grapefruit juice interactions, patients treated with fentanyl should preferably avoid the consumption of grapefruit and grapefruit juice. In addition, patients receiving transdermal formulations of fentanyl should be cautioned that drug interactions and drug effects may be observed for a prolonged period beyond removal of the patch, as significant amounts of fentanyl are absorbed from the skin for 17 hours or more after the patch is removed.

dezocine food

Applies to: dezocine

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
