I would suggest you call your local pharmacist to get this answer - they have the most knowledge about interactions between medications and "nutritional supplements."
Also, it is best not to receive answers online to these types of medical questions. There are many contradictory answers online to these types of medical questions, because some websites explain that taking ginkgo biloba with antidepressants will induce serotonin syndrome or seizures, (1) while other websites actually encourage taking ginkgo biloba with antidepressants to reduce the effects of decreased sexual performance that many SSRIs cause.(2)
So it is best to ask a professional.
