Interactions between your drugs
acetaminophen butalbital
Applies to: Ide-cet (acetaminophen / butalbital / caffeine) and Ide-cet (acetaminophen / butalbital / caffeine)
Using acetaminophen together with butalbital may alter the effects of acetaminophen and cause serious side effects that may affect your liver. Call your doctor immediately if you experience a fever, chills, joint pain or swelling, excessive tiredness or weakness, unusual bleeding or bruising, skin rash or itching, loss of appetite, nausea, vomiting, or yellowing of the skin or the whites of your eyes. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
butalbital suzetrigine
Applies to: Ide-cet (acetaminophen / butalbital / caffeine) and suzetrigine
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of suzetrigine and M6-SUZ, a major active metabolite whose systemic exposure (AUC) at steady state is approximately 3 times that of the parent drug but exhibits 3.7-fold less potency in blocking the NaV1.8 voltage-gated sodium channels responsible for transmission of pain signals to the spinal cord and brain. Both suzetrigine and M6-SUZ are primarily metabolized by CYP450 3A4. When a single dose of suzetrigine was administered with the potent CYP450 3A4 inducer rifampin at steady state, mean suzetrigine peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 80% and 93%, respectively, while mean Cmax of M6-SUZ increased by 30% and AUC decreased by 85%. Coadministration with efavirenz, a moderate CYP450 3A4 inducer, is predicted to decrease the mean Cmax and AUC of suzetrigine by 29% and 63%, respectively, while the mean Cmax of M6-SUZ is predicted to increase by 30% and AUC to decrease by 60%. The interaction has not been studied with other, less potent CYP450 3A4 inducers.
MANAGEMENT: The potential for diminished pharmacologic effects of suzetrigine should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.
Drug and food interactions
suzetrigine food
Applies to: suzetrigine
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit and/or grapefruit juice may increase the plasma concentrations of suzetrigine and M6-SUZ, a major active metabolite whose systemic exposure (AUC) at steady state is approximately 3 times that of the parent drug but exhibits 3.7-fold less potency in blocking the NaV1.8 voltage-gated sodium channels responsible for transmission of pain signals to the spinal cord and brain. The proposed mechanism for the interaction is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. When a single dose of suzetrigine was administered with itraconazole, a potent CYP450 3A4 inhibitor, mean suzetrigine peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.5- and 4.8-fold, respectively, while mean Cmax of M6-SUZ decreased by 32% and AUC increased by 4.4-fold. Coadministration of fluconazole, a moderate CYP450 3A4 inhibitor, with suzetrigine dosed according to the manufacturer's recommended dosage modification is predicted to increase the mean Cmax and AUC of suzetrigine by 1.4- and 1.5-fold, respectively, while the mean Cmax and AUC of M6-SUZ are predicted to increase by 1.1- and 1.2-fold, respectively, compared to suzetrigine administered at the regular recommended dosage without fluconazole. In general, the effects of grapefruit products are concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.
ADJUST DOSE INTERVAL: Food may delay the absorption of suzetrigine without impacting the overall systemic exposures to parent drug and M6-SUZ. Administration of suzetrigine 100 mg (the first dose) with a high-fat meal (800 to 1000 calories; 50% from fat), a moderate-fat meal (600 calories; 30% from fat), and a low-fat meal (<=500 calories; <=25% from fat) resulted in decreased initial plasma concentrations of suzetrigine and M6-SUZ compared to administration in a fasted state. The median time to reach peak plasma concentration (Tmax) for suzetrigine and M6-SUZ when administered with either a high-fat or moderate-fat meal was 5 hours and 24 hours, respectively, versus 3 hours and 8 to 10 hours, respectively, when administered in the fasted state. The Cmax and AUC of suzetrigine and M6-SUZ were not affected by any of the meal conditions, including a high-fat meal consumed one hour after suzetrigine. Administration of the second suzetrigine dose of 50 mg with or without regard to meals is also predicted to have no effect on the systemic exposures of suzetrigine and M6-SUZ.
MANAGEMENT: Patients should avoid consumption of foods or drinks containing grapefruit during treatment with suzetrigine. The starting dose of 100 mg should be taken on an empty stomach at least 1 hour before or 2 hours after food, although clear liquids (e.g., water, apple juice, vegetable broth, tea, black coffee) may be consumed during this time. Subsequent doses may be taken with or without food.
acetaminophen food
Applies to: Ide-cet (acetaminophen / butalbital / caffeine)
Ask your doctor before using acetaminophen together with ethanol (alcohol). This can cause serious side effects that affect your liver. Call your doctor immediately if you experience a fever, chills, joint pain or swelling, excessive tiredness or weakness, unusual bleeding or bruising, skin rash or itching, loss of appetite, nausea, vomiting, or yellowing of the skin or the whites of your eyes. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
butalbital food
Applies to: Ide-cet (acetaminophen / butalbital / caffeine)
Ask your doctor before using butalbital together with ethanol (alcohol), this can add to dizziness, drowsiness and other side effects of butalbital. Be careful if you drive or do activities that require you to be awake and alert. Talk with your doctor before using any medications together, or drinking alcohol with butalbital. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
acetaminophen food
Applies to: Ide-cet (acetaminophen / butalbital / caffeine)
Consumer information for this interaction is not currently available.
MONITOR: Smoking cessation may lead to elevated plasma concentrations and enhanced pharmacologic effects of drugs that are substrates of CYP450 1A2 (and possibly CYP450 1A1) and/or certain drugs with a narrow therapeutic index (e.g., flecainide, pentazocine). One proposed mechanism is related to the loss of CYP450 1A2 and 1A1 induction by polycyclic aromatic hydrocarbons in tobacco smoke; when smoking cessation agents are initiated and smoking stops, the metabolism of certain drugs may decrease leading to increased plasma concentrations. The mechanism by which smoking cessation affects narrow therapeutic index drugs that are not known substrates of CYP450 1A2 or 1A1 is unknown. The clinical significance of this interaction is unknown as clinical data are lacking.
MANAGEMENT: Until more information is available, caution is advisable if smoking cessation agents are used concomitantly with drugs that are substrates of CYP450 1A2 or 1A1 and/or those with a narrow therapeutic range. Patients receiving smoking cessation agents may require periodic dose adjustments and closer clinical and laboratory monitoring of medications that are substrates of CYP450 1A2 or 1A1.
