Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

One case report has suggested that ibuprofen may cause phenytoin toxicity. However, data have been conflicting: one pharmacokinetic study did not demonstrate an effect and another study demonstrated that ibuprofen displaces phenytoin from protein binding sites in vitro. The clinical significance is unknown. Clinical and laboratory monitoring for altered phenytoin effect is recommended.
