Fanapt® (iloperidone) tablets are indicated for the treatment of schizophrenia in adults.
Deciding to look at alternate medications is something your doctor may do. Your doctor needs to consider that Fanapt® may change your heart rhythm (meaning there is more time between heartbeats). When taking other drugs that may cause this same change in heart rhythm, you are at a higher risk of a serious, even life-threatening medical issue (torsade de pointes), which may result in sudden death. In many cases, your doctor may prescribe another medication like Fanapt® first.
Fanapt® needs to be taken as directed starting at a low dose
and slowly increasing the strength. This may delay the control of symptoms in
the first 1 to 2 weeks of treatment. Treatment with Fanapt® for longer than 6
weeks has not been evaluated. Your doctor will evaluate the long-term
usefulness of Fanapt® for you.
