  history of such a syndrome (electrical disturbance of the heart), as taking rufinamide could make it worse.

Other medicines and Rufinamide

Tell the doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. If you are taking the following medicines:

Antiepileptic medicines and Rufinamide
