How does this medication work? What will it do for me?

Cariprazine belongs to the class of medications called antipsychotics. It is used to treat schizophrenia and bipolar disorder. It does not cure these medical conditions, but helps to manage symptoms by affecting the actions of certain chemical messengers in the brain.

Schizophrenia can cause symptoms such as hallucinations (e.g., hearing, seeing, or sensing things that are not there), delusions, unusual suspiciousness, and emotional withdrawal. People with this condition may also feel depressed, anxious, or tense. Bipolar disorder was previously referred to as manic depressive illness; it causes alternating episodes of mania and depression. Cariprazine is used for short-term treatment of both manic and depressive symptoms.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Are any nutrients depleted by this medication?

Some medications can affect vitamin and nutrient levels in the body. Below is a list of nutrient depletions associated with this medication. Talk to your doctor or pharmacist about whether taking a supplement is recommended or if you have any questions or concerns.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abnormal heart rhythms: This medication may cause an abnormal heart rhythm problem called QT prolongation. If you have a history of QT prolongation, slow or irregular heartbeat, irregular heart rhythm, heart failure, heart attack, heart disease, taking other medications known to cause QT prolongation, or a family history of sudden cardiac death at less than 50 years of age, discuss with your doctor how this medication may affect your medical condition, or how your medical condition may affect the dosing and effectiveness of this medication. Your doctor will perform tests at regular intervals to monitor for any changes in your heart rhythm. 

Alcohol and other medications that cause drowsiness: Do not combine this medication with alcohol or other medications that cause drowsiness (e.g., antidepressants, sleeping pills, anxiety medications) since additive drowsiness can occur and be dangerous.

Blood clots: Cariprazine can increase the chance of blood clot formation, causing reduction of blood flow to organs or the extremities. 

If you have a history of clotting, you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision or difficulty speaking, contact your doctor immediately.

Body temperature: Cariprazine, like other antipsychotic medications, may interfere with your body's ability to regulate body temperature. People who exercise vigorously, who are exposed to extreme heat, are dehydrated, or are taking anticholinergic medications (e.g., benztropine, oxybutynin) are more at risk. Contact your doctor as soon as possible if you feel very hot and are unable to cool down.

Take care to avoid overheating during strenuous exercise or in hot temperatures, and avoid becoming dehydrated by drinking enough fluids.

Diabetes: Cariprazine may increase blood sugar for people with diabetes or those who are at risk for diabetes. If you have diabetes, monitor your blood sugar frequently as recommended by your doctor. If you experience symptoms of high blood sugar (e.g., increased urination, increased thirst, increased eating, and weakness) while taking this medication, contact your doctor.

Drowsiness/reduced alertness: Cariprazine may cause drowsiness, light-headedness, or impaired judgement, which could interfere with your ability to do activities requiring alertness, such as driving a car. Avoid these activities if the medication affects you in this way. Avoid alcohol while taking cariprazine as it may increase your drowsiness.

Infection: Rarely, this medication will reduce the number of cells that fight infection in the body (white blood cells). Tell your doctor if you notice more frequent signs of an infection, such as fever or chills, severe diarrhea, shortness of breath, prolonged dizziness, headache, stiff neck, weight loss, or listlessness. Your doctor will do blood tests regularly to monitor the number of specific types of blood cells in your blood.

Low blood pressure: Some people taking cariprazine may experience sudden blood pressure drops when getting up from a sitting or lying position. These blood pressure drops could lead to dizziness, lightheadedness, and falls. If you experience this problem, try getting up more slowly. If it persists or if you faint, contact your doctor.

If you have or have had heart disease, stroke, "mini-stroke", or are at risk of experiencing low blood pressure (e.g., dehydration, taking medications for high blood pressure), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Neuroleptic malignant syndrome (NMS): This medication may cause a potentially fatal reaction called neuroleptic malignant syndrome (NMS). If you develop symptoms of NMS, such as muscle stiffness, fever, confusion, sweating, or irregular heartbeat, stop taking this medication and seek immediate medical attention.

Seizures: Seizures have occurred for people taking cariprazine. If you have a history of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience a seizure while taking this medication, get immediate medical attention.

Suicidal behaviour: People taking this medication as part of treatment for depression may feel agitated (restless, anxious, aggressive, emotional, and feeling not like themselves), or they may want to hurt themselves or others. These symptoms may occur within several weeks after starting this medication. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behaviour changes while taking this medication.

Swallowing problems: People taking cariprazine may have difficulty swallowing. Seniors and people on other antipsychotic medications should be closely monitored by their doctor for swallowing problems while they are using this medication. If you experience difficulty swallowing while taking this medication, contact your doctor.

Tardive dyskinesia: People taking this medication may develop tardive dyskinesia, a syndrome of uncontrolled body movements. This syndrome may be irreversible. If you develop uncontrolled or unusual body movements, contact your doctor as soon as possible.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Women who may become pregnant should use effective birth control while taking cariprazine and for at least 12 weeks after stopping the medication. It is not known if this medication affects how well hormonal birth control works. Because of the potential for this medication to affect hormonal birth control (e.g., implants, birth control pills), a second type of birth control should be used.

Breast-feeding: It is not known if cariprazine passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children.

Seniors There may be a higher risk of strokes, heart attacks, and deaths associated with the use of cariprazine by people with dementia. Talk to your doctor about the risks and benefits of using this medication.
