In clinical studies, some of the most common side effects that were reported with this medication included
headaches, drowsiness, a rapid heart rate, and weight gain. In most cases, these side effects are minor and either do not require treatment or can be treated easily by you or your healthcare provider.
However, a number of other negative effects have been reported with Invega. For example, the medicine can cause a dangerous irregular heart rhythm called QT prolongation. It can also cause

diabetes, or cause a life-threatening condition called neuroleptic malignant syndrome.
