Be sure to mention any of the following: anticholinergics such as atropine (Atropen, Duodote, Enlon-Plus), benztropine (Cogentin), dicyclomine (Bentyl), glycopyrrolate (Robinul), hyoscyamine, propantheline (Pro-Banthine), and scopolamine (Transderm Scop); carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Teril); itraconazole (Onmel, Sporanox); ketoconazole; medications for blood pressure; and rifampin (Rifadin, Rimactane, in Rifamate, Rifater). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with cariprazine, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
  • tell your doctor what herbal products you are taking, especially St. John’s wort.
  • tell your doctor if you have a low number of white blood cells, or if you have ever developed a low number of white blood cells as a side effect of a medication that you took. Tell your doctor if you have or have ever had seizures; a stroke; a ministroke; a heart attack; heart failure; irregular heartbeat;; trouble keeping your balance; difficulty swallowing;or heart, liver, or kidney disease. Also tell your doctor if you have severe vomiting, diarrhea or signs of dehydration now, or if you develop these symptoms at any time during your treatment.
  • tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breastfeeding. If you become pregnant while taking cariprazine, call your doctor. Cariprazine may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
  • you should know that cariprazine may make you drowsy, and may affect your ability to think clearly, make decisions, and react quickly. Do not drive a car or operate machinery during your treatment with cariprazine until you know how this medication affects you.
  • you should know that you may experience hyperglycemia (increases in your blood sugar) while you are receiving this medication, even if you do not already have diabetes. If you have schizophrenia, you are more likely to develop diabetes than people who do not have schizophrenia, and receiving cariprazine or similar medications may increase this risk. Tell your doctor immediately if you have any of the following symptoms during your treatment: extreme thirst, frequent urination, extreme hunger, blurred vision, or weakness. It is very important to call your doctor as soon as you have any of these symptoms because high blood sugar can cause a serious condition called ketoacidosis.

Symptoms of ketoacidosis include dry mouth, nausea and vomiting, shortness of breath, breath that smells fruity, and decreased consciousness.
  • you should know that cariprazine may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking cariprazine. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
  • you should know that cariprazine may make it harder for your body to cool down when it gets very hot. Tell your doctor if you plan to do vigorous exercise or be exposed to extreme heat. Be sure to drink plenty of water and call your doctor if you experience any of the following symptoms: feeling very hot, sweating heavily, not sweating even though it is hot, dry mouth, excessive thirst, or decreased urination.

Cariprazine Dosage

Cariprazine comes as a capsule to take by mouth. It is usually taken once a day with or without food. Take cariprazine at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cariprazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of cariprazine and gradually increase your dose depending on how well the medication works for you, and the side effects you experience.

Cariprazine may help control your symptoms but will not cure your condition. It may take several weeks or longer before you feel the full benefit of cariprazine. Continue to take cariprazine even if you feel well. Do not stop taking cariprazine without talking to your doctor. Talk to your doctor if you do not feel like you are getting better during your treatment with cariprazine.


Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body’s response to cariprazine.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
