Lamotrigine can be used to treat the following partial seizures, primary generalized tonic-clonic seizures, bipolar I disorder maintenance and Lennox-Gastaut syndrome. Off-label uses include treating acute bipolar depression, fibromyalgia, schizophrenia, and unipolar depression. This activity covers lamotrigine, including mechanism of action, pharmacology, adverse event profiles, eligible patient populations, contraindications, monitoring, and highlights the interprofessional team's role in managing lamotrigine therapy. Objectives: Explain the mechanism of action of lamotrigine. Identify both approved and off-label indications for lamotrigine. Summarize the potential drug-drug interactions for lamotrigine. Describe interprofessional team strategies for improving care coordination and communication to use lamotrigine to enhance patient outcomes. Access free multiple choice questions on this topic.

With excessive lamotrigine overdoses, some reportedly as high as 16 g, fatalities have occurred following complications, including seizures, coma, and conduction abnormalities. Immediate-release lamotrigine is rapidly absorbed, and inducing emesis may not be the appropriate intervention in this instance. However, hospitalization and supportive care are indicated, along with the usual airway-protective precautions. As of this writing, there is no known specific antidote for lamotrigine toxicity.[14]

Lamotrigine is best prescribed, administered, dispensed, and managed by an interprofessional healthcare team. This team includes all clinicians, nursing staff, and pharmacists. The drug is often prescribed by the primary care provider, internist, neurologist, and pain specialist to treat several other disorders besides seizures. However, all prescribers should be aware of the United States Boxed Warning, which states that lamotrigine can cause serious rashes requiring hospitalization and discontinuation of this medication. Rash severity varies but includes a risk for Stevens-Johnson syndrome. It is also worth noting that discontinuing lamotrigine may not prevent a rash from becoming life-threatening. Patient education should instruct the patient to continuously monitor for signs of improvement after discontinuing the medication.[15] Pharmacists need to monitor the patient's medication record, alert the prescriber to possible drug-drug interactions, verify appropriate dosing, and offer patient counsel about their medication. Nursing can serve as an additional resource for patient counseling and coordinate activities among clinicians and other specialties involved in patient care. All interprofessional team members must engage in open communication and patient data sharing to ensure that everyone on the team operates on the same accurate, up-to-date information. This interprofessional team approach helps achieve optimal patient outcomes and reduce the risk of adverse events.
