Is administration of IV or PO lacosamide, for management of status epilepticus, contraindicated in patient's with prolonged PR interval or first degree AV block on admission?  

Use of IV or PO lacosamide is known to cause dose dependent PR prolongation which is often "not clinically significant" and reversible. However, lately there has been some hesitation amongst providers towards avoiding use of lacosamide in patients with status epilepticus and prolonged PR interval at baseline. Would like to hear from experts on this forum regarding their thoughts on this topic.
