Interactions between your drugs

Major

rifAMPin HYDROcodone

Applies to: Rimactane (rifampin) and Xylon 10 (hydrocodone / ibuprofen)

MONITOR CLOSELY: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of opioids that are primarily metabolized by the isoenzyme such as butorphanol, fentanyl, hydrocodone, and oxycodone. Reduced efficacy or withdrawal symptoms may occur in patients maintained on their narcotic pain regimen following the addition of a CYP450 3A4 inducer. Conversely, discontinuation of the inducer may increase opioid plasma concentrations and potentiate the risk of overdose and fatal respiratory depression.

MANAGEMENT: Pharmacologic response to the opioid should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the opioid dosage adjusted as necessary.

ibuprofen rifAMPin

Applies to: Xylon 10 (hydrocodone / ibuprofen) and Rimactane (rifampin)

MONITOR: Coadministration of rifampin with agents known to induce hepatotoxicity may potentiate the risk of liver injury. There are various possible mechanisms related to rifampin-associated hepatotoxicity described in product labeling and medical literature, however no consensus has been made. These include increased mitochondrial oxidative stress, apoptotic liver cell injury (in rodent studies), the development of cholestasis, hepatic lipid accumulation, and elevated toxic metabolites caused by rifampin-mediated induction of cytochrome P450 enzymes. Cases of drug-induced liver injury (including fatal cases) have been reported within the first few days to months following rifampin treatment initiation. Additional data suggests that 1-2% of patients receiving rifampin monotherapy for tuberculosis prophylaxis experience hepatotoxicity. The severity of hepatotoxicity from rifampin ranges from asymptomatic elevations in liver enzymes, jaundice and/or hyperbilirubinemia, and symptomatic self-limiting hepatitis to fulminant liver failure and death. In most cases, liver function recovers upon on discontinuation of rifampin treatment, however, progression to acute liver failure requiring liver transplantation is possible. Known risk factors that may predispose the patient to rifampin related hepatotoxicity include: coadministration with other hepatotoxic agents, alcoholism, existing liver disease, malnutrition, extensive liver tuberculosis, liver adenocarcinoma and biliary tract neoplasm. Clinical data have been reported with concurrent use of rifampin with other antituberculosis agents (e.g. isoniazid, pyrazinamide), acetaminophen, antiretroviral agents (e.g., saquinavir/ritonavir) and halothane. Data with other hepatotoxic agents are limited.

MANAGEMENT: Caution and close clinical monitoring should be considered if rifampin is coadministered with other hepatotoxic medications. In addition, the manufacturer recommends patients with impaired liver function only be given rifampin in cases of necessity and then under strict medical supervision. Some authorities consider rifampin treatment in patients with existing liver injury contraindicated (Canada). In cases where coadministration of rifampin with hepatotoxic agents is required, careful monitoring of liver function, especially ALT and AST, should be done prior to therapy and then every 2 to 4 weeks during therapy. If hepatic damage is suspected, rifampin should be immediately discontinued. Furthermore, if hepatitis is attributed to rifampin in patients with tuberculosis, alternative agents should be considered. Patients should be instructed to contact their physician immediately if they experience symptoms such as itching, weakness, loss of appetite, nausea, vomiting, abdominal pain, yellowing of the eyes or skin or dark urine.

Drug and food interactions

Major

HYDROcodone food

Applies to: Xylon 10 (hydrocodone / ibuprofen)

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.

rifAMPin food

Applies to: Rimactane (rifampin)

GENERALLY AVOID: Concurrent use of rifampin in patients who ingest alcohol daily may result in an increased incidence of hepatotoxicity. The increase in hepatotoxicity may be due to an additive risk as both alcohol and rifampin are individually associated with this adverse reaction. However, the exact mechanism has not been established.

ADJUST DOSING INTERVAL: Administration with food may reduce oral rifampin absorption, increasing the risk of therapeutic failure or resistance. In a randomized, four-period crossover phase I study of 14 healthy male and female volunteers, the pharmacokinetics of single dose rifampin 600 mg were evaluated under fasting conditions and with a high-fat meal. Researchers observed that administration of rifampin with a high-fat meal reduced rifampin peak plasma concentration (Cmax) by 36%, nearly doubled the time to reach peak plasma concentration (Tmax) but reduced overall exposure (AUC) by only 6%.

MANAGEMENT: The manufacturer of oral forms of rifampin recommends administration on an empty stomach, 30 minutes before or 2 hours after meals. Patients should be encouraged to avoid alcohol or strictly limit their intake. Patients who use alcohol and rifampin concurrently or have a history of alcohol use disorder may require additional monitoring of their liver function during treatment with rifampin.

ibuprofen food

Applies to: Xylon 10 (hydrocodone / ibuprofen)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.
