Invega® (paliperidone) is a schizophrenia medication that belongs to a class of drugs known as atypical antipsychotics. Although many people tolerate this medication well and generally do not experience any problems with Invega, dangers associated with the use of this medicine should be reviewed with your healthcare provider before you begin treatment.
It is important to know that, like any medication, side effects may occur with Invega. In clinical studies, a number of people taking this antipsychotic drug reported experiencing indigestion or heartburn, headaches, nausea, and dry mouth. These side effects are typically mild and do not require medical attention in most cases, but certain problems with Invega are potentially dangerous and should be reported to your healthcare provider immediately.
For example, one of the primary dangers of Invega use is the increased risk of developing a life-threatening irregular heart rhythm (arrhythmia) called QT prolongation. People with long QT syndrome should not take Invega, and Invega should not be combined with other medications that can prolong the QT interval (see Invega Drug Interactions).
