Interactions between your drugs


sarilumab benzhydrocodone

Applies to: sarilumab and acetaminophen / benzhydrocodone

Consumer information for this interaction is not currently available.

MONITOR: Plasma concentrations of drugs that are CYP450 substrates may decrease following the initiation of interleukin (IL) inhibitors, tumor necrosis factor (TNF) blockers, or interferon (IFN) inhibitors in patients with chronic inflammatory diseases. Because the formation of hepatic CYP450 enzymes is down-regulated during infection and chronic inflammation by increased levels of certain cytokines (e.g., interleukins-1, -6, and -10; tumor necrosis factor alpha; interferons), treatment targeting these cytokines may restore or normalize CYP450 enzyme levels resulting in increased metabolism of these drugs. In vitro studies showed that tocilizumab, an IL-6 inhibitor, has the potential to impact expression of various hepatic microsomal enzymes including CYP450 1A2, 2B6, 2C9, 2C19, 2D6, and 3A4. Its effects on CYP450 2C8 or transporters is unknown. In vivo studies with omeprazole (a substrate of CYP450 2C19 and 3A4) and simvastatin (a substrate of CYP450 3A4 and OATP 1B1) showed decreases of up to 28% and 57% in systemic exposure, respectively, one week following a single dose of tocilizumab. Likewise, simvastatin and simvastatin acid exposures decreased by 45% and 36%, respectively, in 17 patients with rheumatoid arthritis one week following a single 200 mg subcutaneous dose of sarilumab, another IL-6 inhibitor. A role for other interleukins such as IL-12, IL-17A, or IL-23 in the regulation of CYP450 enzymes has not been established, and it is not known whether antagonists of these interleukins (e.g., guselkumab, ixekizumab, secukinumab, tildrakizumab, ustekinumab) would similarly affect CYP450 metabolism.

MANAGEMENT: Caution is advised when treatments targeting cytokines such as interleukins, tumor necrosis factors, or interferons are prescribed to patients receiving concomitant drugs that are CYP450 substrates, particularly those with narrow therapeutic ranges (e.g., antiarrhythmics, anticonvulsants, immunosuppressants, theophylline) or sensitive substrates where decreases in plasma levels may be significant or undesirable (e.g., oral contraceptives, statins, benzodiazepines, opioids). Clinical and/or laboratory monitoring should be considered following the initiation or withdrawal of such treatments, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly. Clinicians should note that the effects of IL inhibitors, TNF blockers, and IFN inhibitors on CYP450 activities may persist for several weeks after stopping therapy.

Drug and food interactions


benzhydrocodone food

Applies to: acetaminophen / benzhydrocodone

Consumer information for this interaction is not currently available.

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.
