About LACONEXT INJECTION

LACONEXT INJECTION belongs to the class of anticonvulsants used to treat partial onset seizures (seizures that affect only one portion of the brain) in adults and children one month or older who cannot take oral treatments. LACONEXT INJECTION is also used in conjunction with other medications to manage primary generalized tonic-clonic seizures (previously known as a grand mal seizure, a seizure affecting the entire body) in adults and children four years of age and older who are unable to take oral medications. Focal or partial-onset seizures are characterized by abnormal electrical activity in only one brain hemisphere.

LACONEXT INJECTION contains lacosamide, which treats seizures by decreasing disorganized electrical activity in the brain.

LACONEXT INJECTION is administered by a healthcare professional; do not self-administer. In some cases, you may experience common side effects like coordination problems, double vision, headache, nausea, vomiting, sleepiness, and unsteady walking. Most of these side effects of LACONEXT INJECTION do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Don’t stop taking LACONEXT INJECTION even if your condition is controlled, as abrupt stopping may cause the recurrence of the seizures. Before taking the LACONEXT INJECTION, inform your doctor if you are allergic to lacosamide or other ingredients. Inform your doctor if you are previously diagnosed with depression, kidney or liver impairment, and heart conditions. Before taking LACONEXT INJECTION, inform your doctor about your medical history and other medications you are currently taking in order to rule out any potential negative effects.
