Summary Reports
Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
REXULTI is used in adults:
- for the treatment of schizophrenia;
- along with antidepressant medication for the treatment of major depressive disorder (MDD)
Schizophrenia is characterized by symptoms such as:
- hallucinations; hearing, seeing or sensing things that are not there,
- suspiciousness, mistaken beliefs,
- incoherent speech and behavior and emotional flatness.
People with schizophrenia may also feel depressed, guilty, anxious or tense.
Depression is a condition with symptoms such as:
- feeling sad
- loss of interest and enjoyment
- a change in appetite or weight
- difficulty concentrating or sleeping
- feeling tired
- headaches
- unexplained aches and pain
REXULTI is not a cure, but it can help manage symptoms in adult patients.
What it does
REXULTI belongs to a group of medicines called atypical antipsychotic drugs. Antipsychotic drugs affect the chemicals (neurotransmitters) in the brain that allow nerve cells to talk to each other. Illnesses that affect the brain, like schizophrenia or depression, may be due to certain naturally occurring chemicals (called neurotransmitters) in the brain being out of balance. These imbalances may cause some of the symptoms you may be experiencing. Exactly how REXULTI works is unknown.

Low Blood Pressure
Some people may faint, or get lightheaded and dizzy, especially when getting up from a lying or sitting position.
