Hi, sorry I just saw your questions. I had a ruptured AVM and taking Keppra. About 2 months later, all of a sudden, my taste had changed. I became sensitive to sweets. Food didn’t taste the same to me anymore. I had asked the expert doctors on my neurological team but none knew the reason for this. A couple weeks later my Keppra was discontinued. I was hoping my altered taste was caused by the medication. Now almost 3 years later the issue has not gone away. In addition I have a bitter taste. I currently take no medications. My last one was the Keppra 3 years ago.
