Interactions between your drugs
PHENobarbital mavorixafor
Applies to: Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine) and Xolremdi (mavorixafor)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with strong CYP450 3A4 inducers may significantly reduce the plasma levels and effects of mavorixafor, which is primarily metabolized by the isoenzyme. This potential interaction is based upon a mechanistic understanding of the elimination of mavorixafor. Clinical data are not available.
MANAGEMENT: The manufacturer recommends avoiding concomitant use of mavorixafor with strong CYP450 3A4 inducers due to a potentially significant reduction in its efficacy.
atropine hyoscyamine
Applies to: Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine) and Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine)
Using atropine together with hyoscyamine may increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, irregular heartbeat, confusion, and memory problems. Side effects may be more likely to occur in the elderly or those with a debilitating condition. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor if you have any questions or concerns. 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.

Using PHENobarbital together with scopolamine may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor if you have any questions or concerns. 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.
hyoscyamine scopolamine
Applies to: Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine) and Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine)
Using hyoscyamine together with scopolamine may increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, irregular heartbeat, confusion, and memory problems. Side effects may be more likely to occur in the elderly or those with a debilitating condition. You should avoid or limit the use of alcohol while being treated with these medications.

Drug and food interactions
mavorixafor food
Applies to: Xolremdi (mavorixafor)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit products may significantly increase the plasma concentrations and effects of mavorixafor, which is primarily metabolized by the isoenzyme CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. A study examining mavorixafor in combination with the strong CYP450 3A4 and P-glycoprotein inhibitor, itraconazole, suggests an increase in mavorixafor's systemic exposure (AUC) of approximately 2-fold. Clinical data with grapefruit products are not available. Pharmacokinetic interactions involving grapefruit are subject to a high degree of interpatient variability and can also be affected by the product and amount consumed; therefore, the extent to which a given patient may be affected is difficult to predict. Additionally, since mavorixafor is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death.
ADJUST DOSING INTERVAL: Food may significantly reduce the peak plasma concentration (Cmax) and systemic exposure (AUC) of mavorixafor. When a single-dose of mavorixafor (400 mg) was administered with a high-fat meal (1000 calories, 50% fat) to healthy subjects, the Cmax and AUC decreased by 66% and 55%, respectively. Similarly, when the same dose was given with a low-fat meal (500 calories, 25% fat) to healthy subjects, mavorixafor's Cmax and AUC decreased by 55% and 51%, respectively. Additionally, a single dose of mavorixafor (400 mg) administered with a low-fat meal to healthy subjects following an overnight fast resulted in a 14% higher Cmax and an 18% lower AUC than those obtained from subjects who fasted for an additional 4 hours after the dose.
MANAGEMENT: Mavorixafor should be taken on an empty stomach after an overnight fast, 30 minutes before food. Patients should be advised to avoid eating or drinking products containing grapefruit, as this could increase the risk of experiencing adverse effects from mavorixafor such as QT prolongation.
PHENobarbital food
Applies to: Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine)
Ask your doctor before using PHENobarbital together with ethanol (alcohol), this can add to dizziness, drowsiness and other side effects of PHENobarbital. 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 PHENobarbital. 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.
atropine food
Applies to: Hyosophen (atropine / hyoscyamine / phenobarbital / scopolamine)
Ask your doctor before using atropine together with ethanol (alcohol). Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking atropine.

If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination. 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.
