Interaction Summary
The addition of Ginkgo biloba and/or St. John's Wort to therapy with busPIRone and fluoxetine may have precipitated a hypomanic episode in a case report[1]. It is unclear if Ginkgo or St. John's Wort, the combination of both, or other patient factors, contributed to the effect. Caution is advised.

How To Manage Interaction
Caution patients taking busPIRone to discuss the use of nonprescription medicines, herbs, and dietary supplements with their doctor or pharmacist. If a patient presents with hypomanic symptoms when taking busPIRone, inquire about the use of nonprescription medicines, herbs, and dietary supplements. It is recommended to avoid Gingko in patients taking busPIRone, especially in combination with other psychotropic medicines.
Mechanism Of Interaction
Unknown
Literature Reports
A) A 42-year-old female experienced symptoms consistent with a mixed hypomanic episode following concomitant use of fluoxetine, busPIRone, Ginkgo biloba, and St. John's Wort. The symptoms resolved following discontinuation of Ginkgo and St. John's Wort. The patient was being treated for depression following a mild traumatic brain injury with fluoxetine 20 milligrams (mg) twice daily and busPIRone 15 mg twice daily. Several weeks prior to presentation, busPIRone was increased to 20 mg twice daily for persistent anxiety and the patient began taking Ginkgo biloba, melatonin, and St. John's Wort in unspecified doses. Melatonin was considered unlikely to have contributed to her symptoms. Ginkgo and St. John's Wort were considered possible contributors since they may potentiate antidepressants, and considering the temporal relationship between the use of the herbs and onset of symptoms and discontinuation of the herbs and resolution of symptoms. However, the brain injury was considered a possible contributor [1].
