This medicine may cause blurred vision, double vision, clumsiness, unsteadiness, dizziness, drowsiness, sleepiness, or trouble with thinking.

This medicine can cause changes in heart rhythms, such as a condition called PR prolongation. It may change the way your heart beats and cause lightheadedness, fainting, or serious side effects in some patients. Contact your doctor right away if you have any symptoms of heart rhythm problems, such as a fast, slow, or irregular heartbeat.

Do not stop taking this medicine without first checking with your doctor. Stopping the medicine suddenly may cause your seizures to return or to occur more often. Your doctor may want you to gradually reduce the amount you are using before stopping it completely.

Lacosamide may cause a condition called drug reaction with eosinophilia and systemic symptoms (DRESS), which is a serious allergic reaction affecting multiple body organs (eg, liver or kidney).
