HYDROcodone tedizolid

Applies to: Deconamine CX (guaifenesin / hydrocodone / pseudoephedrine) and tedizolid

MONITOR: The concurrent use of tedizolid with agents that have serotonergic activity including serotonin reuptake inhibitors, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants, 5-HT1 receptor agonists, ergot alkaloids, cyclobenzaprine, lithium, St. John's wort, phenylpiperidine opioids, dextromethorphan, and tryptophan may elevate the risk of developing serotonin syndrome. The proposed mechanism is tedizolid-mediated non-selective and reversible inhibition of monoamine oxidase (MAO), with more potent inhibition of MAO-A than linezolid in vitro. In a retrospective cohort study from January 2015 to July 2023 of 479 adult patients receiving tedizolid, 62% (297/479) received concomitant serotonergic agents, but suspected serotonin syndrome requiring tedizolid discontinuation was found to be rare, occurring in only 0.4% (2/479) of cases. Symptoms of serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucination, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, unstable blood pressure, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea.

MANAGEMENT: Caution and closer monitoring for serotonin syndrome are recommended during concomitant treatment with tedizolid and serotonergic agents, especially during dose escalations, and patients should be instructed to notify their healthcare provider if they experience symptoms of serotonin syndrome. Due to variability and occasionally prolonged half-lives of these coadministered agents, consulting individual product labeling for specific guidance is advised. If serotonin syndrome is suspected, discontinuation of therapy or dose reductions should be considered depending on the severity of the symptoms, and supportive care should be provided. Moderately ill patients may benefit from serotonin antagonists like cyproheptadine or chlorpromazine. Severe cases require consultation with a toxicologist and may need sedation, neuromuscular paralysis, intubation, and mechanical ventilation.

Drug and food interactions

Major

HYDROcodone food

Applies to: Deconamine CX (guaifenesin / hydrocodone / pseudoephedrine)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including hydrocodone. 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 alcohol while taking some sustained-release formulations of hydrocodone may cause rapid release of the drug, resulting in high systemic levels of hydrocodone that may be potentially lethal. Alcohol apparently can disrupt the release mechanism of some sustained-release formulations. In study subjects, the rate of absorption of hydrocodone from an extended-release formulation was found to be affected by coadministration with 40% alcohol in the fasted state, as demonstrated by an average 2.4-fold (up to 3.9-fold in one subject) increase in hydrocodone peak plasma concentration and a decrease in the time to peak concentration. Alcohol also increased the extent of absorption by an average of 1.2-fold (up to 1.7-fold in one subject).

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of hydrocodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of hydrocodone by certain compounds present in grapefruit. Increased hydrocodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.

MANAGEMENT: Patients taking sustained-release formulations of hydrocodone should not consume alcohol or use medications that contain alcohol. In general, potent narcotics such as hydrocodone should not be combined with alcohol. Patients should also avoid consumption of grapefruit or grapefruit juice during treatment with hydrocodone.

Moderate

pseudoephedrine food

Applies to: Deconamine CX (guaifenesin / hydrocodone / pseudoephedrine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

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.
