Other important side effects include:
- increased risk of developing aseptic meningitis and
- reduced white blood cells, red blood cells, and platelets.
Multiorgan failure, including fatal liver disease rarely has been observed during lamotrigine treatment.
As a general rule, anti-seizure medications should not be abruptly stopped because of the possibility of increasing the frequency of seizures. In most cases, the dose of lamotrigine should be gradually lowered over a period of at least two weeks. Antiepileptic medications have been associated with an increased risk of suicidal thinking and behavior. Anyone considering the use of antiepileptic drugs must balance this risk of suicide with the clinical need for the drugs. Patients who are started on therapy should be closely observed for clinical worsening, suicidal thoughts, or unusual changes in behavior.
