Drug Interactions between Choletec and Mepergan Fortis
This report displays the potential drug interactions for the following 2 drugs:
- Choletec (mebrofenin)
- Mepergan Fortis (meperidine/promethazine)
Interactions between your drugs
meperidine promethazine
Applies to: Mepergan Fortis (meperidine / promethazine) and Mepergan Fortis (meperidine / promethazine)
ADJUST DOSE: The central nervous system and respiratory depressant effects of meperidine may be potentiated by concomitant use of other agents with CNS depressant effects. An increased risk of serious adverse reactions such as respiratory depression, hypotension, profound sedation, syncope, coma, and even death should be considered, particularly in elderly or debilitated patients.
MANAGEMENT: Caution and dosage adjustments are advisable when meperidine is used in combination with other narcotic analgesics, general anesthetics, phenothiazines, sedative-hypnotics, tranquilizers, tricyclic antidepressants, or other CNS depressants such as alcohol. A lower dosage of meperidine should be considered initially, then titrated carefully according to pain level and clinical response. Meperidine dosage reductions of 25% to 50% have been recommended for patients receiving phenothiazines and other tranquilizers. Patients should be advised to avoid rising abruptly from a sitting or recumbent position, and to notify their physician if they experience dizziness, lightheadedness, orthostasis, syncope, tachycardia, or excessive CNS effects that interfere with their normal activities. Patients should also avoid driving or operating hazardous machinery until they know how these medications affect them.

meperidine mebrofenin
Applies to: Mepergan Fortis (meperidine / promethazine) and Choletec (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
meperidine food
Applies to: Mepergan Fortis (meperidine / promethazine)
GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. 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.
MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

promethazine food
Applies to: Mepergan Fortis (meperidine / promethazine)
GENERALLY AVOID: Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment. Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines. The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.
MANAGEMENT: Patients should be advised to avoid alcohol during phenothiazine therapy.
