Piramed Topiramate Carbamazepine
MinorAdding Topiramate (Topimax) to Carbamazepine does not cause a clinically significant change in the blood level of Carbamazepine once it has settled at a steady level. So no dose change is normally needed just because of this combination. The only exception the leaflet mentions is a different epilepsy medicine, phenytoin, whose level may rise in some patients when Topiramate is added.
Little or no effect is expected. You usually do not need to change anything, but still tell your doctor or pharmacist about every medicine you take.
