IMPORTANT SAFETY INFORMATION:

Do not take REXULTI if you are allergic to brexpiprazole or any of the ingredients in REXULTI.

REXULTI may cause serious side effects, including:

• Cerebrovascular problems, including stroke, in elderly people with dementia-related psychosis that can lead to death.
• Neuroleptic malignant syndrome (NMS) is a serious condition that can lead to death. Call your healthcare provider or go to the nearest hospital emergency room right away if you develop some or all of the following signs and symptoms of NMS: high fever; changes in your pulse, blood pressure, heart rate, and breathing; stiff muscles; confusion; increased sweating
• Uncontrolled body movements (tardive dyskinesia). REXULTI may cause movements that you cannot control in your face, tongue, or other body parts. Tardive dyskinesia may not go away, even if you stop taking REXULTI. Tardive dyskinesia may also start after you stop taking REXULTI.
• Problems with your metabolism such as:
  • high blood sugar (hyperglycemia) and diabetes. Increases in blood sugar can happen in some people who take REXULTI. Extremely high blood sugar can lead to coma or death. Your healthcare provider should check your blood sugar before you start, or soon after you start REXULTI and then regularly during long term treatment with REXULTI.

    Call your healthcare provider if you develop any of these symptoms of high blood sugar during treatment with REXULTI:

    • feel very thirsty
    • feel very hungry
    • feel sick to your stomach

    • need to urinate more than usual
    • feel weak or tired
    • feel confused, or your breath smells fruity
  • increased fat levels (cholesterol and triglycerides) in your blood. Your healthcare provider should check the fat levels in your blood before you start, or soon after you start REXULTI, and then periodically during treatment with REXULTI.
  • weight gain. You and your healthcare provider should check your weight before you start and often during treatment with REXULTI.
• Unusual and uncontrollable (compulsive) urges. Some people taking REXULTI have had strong unusual urges, to gamble and gambling that cannot be controlled (compulsive gambling). Other compulsive urges include sexual urges, shopping, and eating or binge eating. If you or your family members notice that you are having new or unusual strong urges or behaviors, talk to your healthcare provider.
• Low white blood cell count. Your healthcare provider may do blood tests during the first few months of treatment with REXULTI.
• Decreased blood pressure (orthostatic hypotension) and fainting. You may feel dizzy, lightheaded or pass out (faint) when you rise too quickly from a sitting or lying position.
• Falls. REXULTI may make you sleepy or dizzy, may cause a decrease in your blood pressure when changing position (orthostatic hypotension), and can slow your thinking and motor skills which may lead to falls that can cause fractures or other injuries.
• Seizures (convulsions).

In hot weather, stay inside in a cool place if possible. Stay out of the sun. Do not wear too much clothing or heavy clothing. Drink plenty of water.
