Rexulti (brexpiprazole) is a prescription medicine used to treat schizophrenia in adults. It is also approved as an add-on therapy for major depressive disorder (MDD) in adults. Rexulti is an atypical antipsychotic that helps balance dopamine and serotonin levels in the brain. This helps improve mood, thinking, and behavior. Rexulti comes as oral tablets in strengths ranging from 0.25 mg to 4 mg. It is usually taken once daily, with or without food. A Rexulti prescription is required, and treatment should be monitored by a doctor.

Rexulti (brexpiprazole) works by modulating the activity of two key brain neurotransmitters, dopamine and serotonin. These chemicals influence mood, thoughts, and behaviour. Rexulti does not completely block them. However, it helps bring their signals into better balance. This balance helps reduce schizophrenia symptoms like hallucinations and disorganized thinking. As a result, it can improve mood when combined with antidepressants.
If you miss a dose of Rexulti, take it as soon as you remember. If it is almost time for your next scheduled dose of Rexulti, skip the missed one and continue with your regular schedule. Do not double up to make up for a missed Rexulti dose. Missing doses may reduce the medicine’s effectiveness and could allow symptoms to return or worsen. If you are worried about Rexulti missed dose side effects or have missed several doses, contact your doctor for guidance.
Taking more than the prescribed amount of Rexulti can increase the risk of very serious side effects. This includes extreme sleepiness, irregular heartbeat, dizziness, or movement problems. If you suspect a Rexulti overdose, contact the poison control center or your healthcare provider immediately.

Rexulti Boxed Warning: Increased Death Risk in Adults with Dementia‑related Psychosis
Rexulti carries a boxed warning for increased risk of death in adults with dementia‑related psychosis. It also warns of an increased risk of suicidal thoughts and behaviours in children and young adults (18-24 years) when used for major depressive disorder. Rexulti has not been approved to treat dementia-related psychosis in people with Alzheimer’s disease when agitation is not present. Patients starting treatment should be closely monitored for changes in mood, behaviour, or suicidal thinking.
Follow these Rexulti precautions if you are considering this medication for schizophrenia and MDD:
Rexulti should be stored properly to maintain its effectiveness. The guidelines include:
If Rexulti does not work well or causes side effects, doctors may consider other medications. Rexulti alternatives depend on the condition being treated:
