Rexulti : Uses, Side Effects, Interactions & More

IMPORTANT WARNING:

Important warning for older adults with dementia:
Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities, and can cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as Rexulti. you have a higher chance of death during treatment. Older adults with dementia may also have a higher chance of having a stroke or mini-stroke during antipsychotic treatment.

Rexulti is not approved by the Food and Drug Administration (FDA) for the treatment of behavioral disorders in older adults with dementia. Talk to the doctor who prescribed this medicine if you, a family member, or a loved one have dementia and are taking Rexulti. For more information, visit the FDA website: http://www.fda.gov/Drugs.

Important warning for people who have depression:
A small number of children, adolescents, and young adults (up to age 24) who took medications for depression during clinical trials became suicidal (thinking about harming or killing themselves or planning or trying to do so). Children, adolescents, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, adolescents, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure how great this risk is and how much should be taken into account when deciding whether a child or adolescent should take an antidepressant. Children under 18 years of age should not normally take Rexulti to treat depression, but in some cases, a doctor may decide that Rexulti is the best medicine for treating a child’s condition.

You should know that your mental health can change unexpectedly when you take Rexulti or other antidepressants, even if you are an adult over 24 years of age. You may be suicidal, especially at the beginning of your treatment and any time the dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; new or worsening anxiety; thinking about, or planning or attempting to, hurt or commit suicide; extreme worry; agitation; panic attacks; Difficulty falling asleep or staying asleep; aggressive behavior; irritability; act without thinking; severe restlessness; and mania (frenzied and abnormally excited mood). Make sure your family or caregiver knows what symptoms can be serious so they can call your doctor if you are unable to seek treatment on your own.

Talk to your doctor about the risks of taking Rexulti.

Why is this medication prescribed?

Rexulti (Brexpiprazole) is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thoughts, loss of interest in life, and strong or inappropriate emotions). It is also used with an antidepressant to treat depression when symptoms cannot be controlled with the antidepressant alone. Rexulti is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

How should this medicine be used?

Rexulti (Brexpiprazole) comes as a tablet to take by mouth. It is usually taken once a day. Take Rexulti at around the same times every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Rexulti exactly as directed. Do not take more or less, or take it more often than prescribed by your doctor.
