Interactions
7 DRUG INTERACTIONS 7.1 Strong CYP3A4 or CYP2C9 Inhibitors Patients with renal or hepatic impairment who are taking strong inhibitors of CYP3A4 and CYP2C9 may have a significant increase in exposure to lacosamide. Dose reduction may be necessary in these patients. 7.2 Concomitant Medications that Affect Cardiac Conduction Lacosamide should be used with caution in patients on concomitant medications that affect cardiac conduction (sodium channel blockers, beta-blockers, calcium channel blockers, potassium channel blockers) including those that prolong PR interval (including sodium channel blocking AEDs), because of a risk of AV block, bradycardia, or ventricular tachyarrhythmia.
Warnings
5 WARNINGS AND PRECAUTIONS Monitor patients for suicidal behavior and ideation ( 5.1 ) Lacosamide may cause dizziness and ataxia ( 5.2 ) Cardiac Rhythm and Conduction Abnormalities: Obtaining ECG before beginning and after titration to steady-state maintenance is recommended in patients with underlying proarrhythmic conditions or on concomitant medications that affect cardiac conduction; closely monitor these patients ( 5.3 , 7.2 ) Lacosamide may cause syncope ( 5.4 ) Lacosamide should be gradually withdrawn to minimize the potential of increased seizure frequency ( 5.5 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/ Multi-Organ Hypersensitivity: Discontinue if no alternate etiology ( 5.6 ) 5.1 Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including lacosamide... 4 CONTRAINDICATIONS None. None ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Available data from the North American Antiepileptic Drug (NAAED) pregnancy registry, a prospective cohort study, case reports, and a case series with lacosamide use in pregnant women are insufficient to identify a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Lacosamide produced developmental toxicity (increased embryofetal and perinatal mortality, growth deficit) in rats following administration during pregnancy.
