Has cymbalta (duloxetine) been linked to bruxism? in my situation it clenching of the jawl throughout the day

Although I'm not: A pharmacologist, i'm not aware of the link to bruxing. Consult w your dentist or dental specialist that deals w jaw issues. With bruxism, a special dental mouth guard is a routine first step.

Not that I know of: Bruxism often is the result of stress and can can be helped with the fabrication of an oral appliance. Bruxism if left untreated will damage the dentition and may cause future TMJ issues. Best to be evaluated by a dentist. Hope this helps and thanks for the question.
