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 treatment 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.
- Do not become overheated in hot weather or during exercise or other activities because heatstroke may occur.

Contact the doctor right away if any signs of suicidal thoughts or actions occur.
