Interactions between your drugs

Moderate

HYDROcodone tebentafusp

Applies to: Atuss HX (guaifenesin / hydrocodone) and tebentafusp

MONITOR: Coadministration with tebentafusp may increase the plasma concentrations of drugs that are metabolized by CYP450 pathways. The formation of hepatic CYP450 enzymes is down-regulated by increased levels of certain proinflammatory cytokines that are transiently released during initiation of tebentafusp treatment. Thus, tebentafusp may suppress CYP450 enzymes resulting in increased exposures of some CYP450 substrates. Clinical data are currently lacking but risk of an interaction is expected to be greatest during the first 24 hours of the first 3 tebentafusp doses.

MANAGEMENT: Caution is advised when tebentafusp is coadministered with drugs that are CYP450 substrates, particularly those with narrow therapeutic ranges (e.g., antiarrhythmics, anticonvulsants, immunosuppressants, theophylline) or sensitive substrates where increases in plasma levels may be significant or undesirable (e.g., statins, benzodiazepines, opioids). Clinical and/or laboratory monitoring should be considered following the initiation or withdrawal of tebentafusp, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly.

Drug and food interactions

Major

HYDROcodone food

Applies to: Atuss HX (guaifenesin / hydrocodone)

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.

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.
