What serious side effect is associated with Lamotrigine?

Lamotrigine is primarily associated with the risk of Stevens-Johnson syndrome (SJS), which is a severe and potentially life-threatening skin reaction. SJS is characterized by symptoms such as fever, sore throat, and painful red or purple skin lesions that eventually lead to blistering, peeling, and extensive skin damage. This reaction can also involve mucous membranes, putting patients at risk for infections and serious complications.

The risk of developing SJS is particularly notable when lamotrigine is initiated at too high a dose or the dose is increased too rapidly. Therefore, careful titration of the medication is crucial to minimize this risk. SJS is a unique and critical concern specifically linked to lamotrigine therapy and differentiates it from other side effects that may not carry the same level of severity.

Understanding this risk is vital for healthcare providers when prescribing lamotrigine, as they must ensure they educate patients about the signs and symptoms of SJS for early detection and intervention.
