Other Warnings
Neuroleptic Malignant Syndrome (NMS) is a potentially fatal side effect of Invega. Patients should call their doctor immediately if they have symptoms of high fever, stiff muscles, shaking, confusion, sweating, changes in pulse, and heart rate. These are all potential symptoms for NMS.
Tardive Dyskinesia (TD), a condition that causes uncontrollable movement of the face, tongue, and other body parts, is a serious and sometimes permanent side effect of Invega. Chances of developing TD increase as treatment with Invega is extended over time.
Invega may raise your blood sugar levels. Patients, who have diabetes or risk factors for developing diabetes, should consult their doctor before beginning treatment with Invega.
Invega may raise levels of prolactin in the blood, causing a condition called hyperprolactinemia. This may stop menstrual periods and hinder milk production in women, cause men to develop breasts or prevent men from developing an erection.
