Some seizure medications can have side effects known as cardiotoxicity. This means the medications can potentially damage the heart. Examples of known side effects include:
* pregabalin: increased risk of heart failure
* oxcarbazepine: induce ventricular fibrillation, a severe and life threatening arrhythmia
* carbamazepine: increased risk of AV block or bradycardia (slow heart rate)
Although these are potential side effects, they don’t happen to everyone.
