HYDROcodone mebrofenin
Applies to: KG-Tuss HD (guaifenesin / hydrocodone / pseudoephedrine) and mebrofenin
MONITOR: Prior administration of opioids may delay transit of Technetium Tc 99m mebrofenin due to opioid-induced contraction of the distal common bile duct, which may result in nonvisualization. In one study, a group of investigators reviewed the records of 198 emergency department patients who underwent nuclear hepatobiliary imaging, after excluding those with evidence for pathologic common bile duct (CBD) obstruction. Delayed CBD visualization occurred in 28.6% of subjects who had received opioids (n=56) and 12.0% of subjects who had not received opioids, while delayed imaging was performed in 77.8% and 53.5%, respectively. The relative risk of delayed CBD visualization was 1.46 for meperidine, 4.18 for morphine, and 2.38 for any opioid. Nonetheless, low-dose intravenous morphine has been used during cholescintigraphy to increase biliary pressure, thereby allowing for visualization of gallbladder when there is failure to visualize 60 minutes or more after Technetium Tc 99m mebrofenin injection. Compared to standard cholescintigraphy, morphine-augmented cholescintigraphy has been shown to reduce imaging time and the number of false-positive results.
MANAGEMENT: Nonvisualization may occur in patients who have been receiving opioids prior to cholescintigraphy.

Drug and food interactions
HYDROcodone food
Applies to: KG-Tuss HD (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.

pseudoephedrine food
Applies to: KG-Tuss HD (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.
