My son suffers from Complex Partial Seizures and so far they are not controlled. He is currently on Lamictal 150 MG 2 x daily and Concerta 54MG. The doctor has added Kepra 500 MG x 2 daily. I am concerned about what possible side effects he may have on this combination of medications. Can anyone give me any information positive or negative about your experiences on these medications individually or in the combination of meds. Prior he has been on Topomax, Depakote, Carbatrol, and Zonegran. He has been taken off those meds for different reasons, but most of all they weren't controlling his seizures. Please help me...
