Our objective will be to detail the rules of prescribing the treatment, to describe Steven Johnson syndrome, a serious adverse effect to lamotrigine, to discuss the urgent course of action in the event of severe allergic reactions to lamotrigine as well as the therapeutic options after a hypersensitivity reaction to lamotrigine.
