Bruxism can be part of extrapyramidal symptoms which are known for paroxetine as well as for other SSRIs / SNRIs (i.e. citalopram, escitalopram, fluoxetine, sertraline, venlafaxine).
Tere is increasingly good evidence of a link with selective 5-hydroxytryptamine reuptake inhibitor (selective serotonin reuptake
inhibitor [SSRI]) use,42 especially citalopram and sertraline, which may be dose linked, as well as selective 5-hydroxytryptamine and noradrenaline reuptake inhibitors (serotonin and norepinephrine reuptake inhibitors [SNRIs]) such as venlafaxine, which appears strongly linked with bruxism.
