Keppra and Ginkgo Biloba

I take 750 mg once of the generic brand of Keppra extended release. I was recently put in Zoloft which caused me sexual dysfunction. My doctor told me to try Ginkgo to fix this issue but, I recent read online that it is likely to cause seizures even while on medication. 

I was just wondering if anyone has taken ginkgo and experienced no issues or any issues at all.
