Abstract
|
|
|
|
There are several case reports on risperidone-related bleeding; however, to our knowledge, there is no report about gingival bleeding associated with risperidone in the literature. We presented a case who experienced gingival bleeding when risperidone dose was increased to 0.5 mg/day, and subsided after decreasing the dose to 0.25 mg/day, suggesting a dose-dependent side-effect. The bleeding side effect of risperidone might be caused by several mechanisms, including 5-hydroxytryptamine 2A receptor antagonism. Although bleeding associated with risperidone is rarely reported, clinicians should be aware of this side effect.
