Summary

Stevens–Johnson syndrome (SJS) is a severe, episodic, acute mucocutaneous reaction that is most often elicited by drugs and occasionally by infections. The drugs commonly implicated as the cause of SJS are anticonvulsants, sulfonamides, non-steroidal anti-inflammatory drugs and antibiotics. Carbamazepine (CBZ) has been commonly implicated in SJS. Neuroleptic malignant syndrome (NMS) is a rare, life-threatening but potentially treatable condition. Among the neuroleptics, haloperidol (parenteral) is implicated as a most common drug for NMS. Though rare, association of NMS with CBZ and association of NMS with toxic epidermal necrolysis (TEN) in a single patient after administration of neuroleptics has been reported in the literature before. However, a combination of NMS and SJS in a single patient after administration of CBZ has not been reported so far. We present a patient with seizure who developed SJS and NMS following administration of CBZ.
