Aseptic gingivitis related to quetiapine hemifumarate.

Quetiapine hemifumarate (QF) is widely used in psychiatry and is associated with regularly occurring side effects such as dizziness and metabolic problems. Apart from these typical adverse events the agent has attracted attention for several rare phenomena (priapism, cholestasis, rhabdomyolysis) that indeed feature anecdotal character, but are nevertheless indispensable for a comprehensive understanding of the factual risk profile of quetiapine. We present the first report of aseptic gingivitis associated with QF in a patient with mental retardation.
