Melo G, et al. - Authors reviewed the literature for studies that probed the relationship between use of psychotropic medications and presence of sleep bruxism (SB). Considering use of citalopram, escitalopram, fluoxetine, mirtazapine and sertraline, no increased odds of SB were observed. In children, with regard to anticonvulsants, only barbiturates were associated with SB, while for benzodiazepine, carbamazepine and valproate no increased odds were observed. Methylphenidate was the only psychostimulant evaluated, and in adolescents, an association with SB was observed. Results demonstrated a probable association of medications such as duloxetine, paroxetine, venlafaxine, barbiturates and methylphenidate with SB. Nonetheless, very low overall quality of evidence was considered, hence, experts recommended caution.
