What are two dangerous side effects of lamotrigine?

Lamotrigine is an anticonvulsant medication commonly used to treat epilepsy and bipolar disorder. One of the significant safety concerns associated with its use includes serious skin reactions, notably Stevens-Johnson syndrome (SJS), which can lead to extensive skin detachment and life-threatening complications. This rare but severe reaction is particularly concerning, especially in individuals who are rapidly titrated to high doses or who have concurrent use of valproate, which can increase lamotrigine levels.

Another dangerous side effect associated with lamotrigine is hemophagocytic lymphohistiocytosis (HLH), a severe systemic reaction that can lead to multi-organ failure. This condition is characterized by an uncontrolled immune response that can result in cytopenias, liver dysfunction, and a hyper-inflammatory state. The combination of SJS and HLH represents a critical set of complications that healthcare providers must monitor for when prescribing lamotrigine, especially in vulnerable populations or those with risk factors.

The other options reflect side effects or conditions that are either not closely associated with lamotrigine or are generally less clinically significant in comparison to the dangers posed by SJS and HLH. Therefore, the identification of hemophagocytic lymphohistiocytosis
