- Involuntary and uncontrollable movements may develop in patients taking Amitriptyline. Occurrence is highest among the elderly, especially women. The risk of developing these involuntary movements and the likelihood they will become permanent are increased with long-term use and with high doses. However, it is possible to develop these symptoms after short-term use at low doses. Contact your health care provider at once if any of the following occur: involuntary movements of the tongue, face, mouth, or jaw (eg, protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements), sometimes accompanied by involuntary movements of the arms and legs.
