Why can't I find the physical description of my Trileptal and Oxaarbazepine on any pill identification sites?I've looked up drup identification and nothing matches either one of the pills I have. The trileptal is a light mustard yellow. It is oval. On one side is APO and on the other side it is cerraded. On one half is OXC and on th other side is 300. the oxcarbazipine is also a 300mg tab. It is light brown/tan. One side is cerraded with no markings. The other side has B on one side and 293 on the other side. Are these foreign pills that have been imported?
