How the interaction occurs:
The cause of the interaction is not known. Liquid feedings (such as enteral feedings, tube feedings, or other liquid dietary supplements) seem to have the most important effects on phenytoin blood levels. When liquid feedings are taken with this medicine, they decrease the amount of this medicine absorbed into your bloodstream.
What might happen:
Your blood levels of this medicine may decrease, and therefore the beneficial effects may decrease.
What you should do about this interaction:
If you are receiving liquid feedings (enteral feedings), the feedings should be stopped one to two hours before you take phenytoin. The feedings may be restarted one to two hours after the phenytoin dose. Contact your healthcare professional (e.g., doctor or pharmacist) for more information.Your healthcare professionals may be aware of this interaction and may be monitoring you for it. Do not start, stop, or change your medicine or diet before checking with them first.
