Please read the Medication Guide that comes with Symbyax before you start taking it and each time you get a refill

What are the possible side effects of Symbyax?

Symbyax is associated with possible side effects. Tell your doctor about any side effect that concerns you.

Symbyax may be associated with the following serious risks:

• Suicidal thoughts or actions. Persons taking Symbyax may be more likely to think about killing themselves or actually try to do so, especially when Symbyax is first started or the dose is changed. People close to patients taking Symbyax can help by paying attention to changes in patient's mood or actions. Contact the doctor right away if someone using Symbyax talks about or shows signs of killing him or herself or has sudden changes in mood, behaviors, thoughts, or feelings. If you are taking Symbyax yourself and you start having any of these symptoms, tell your doctor about this right away.
• Strokes and "mini-strokes" called transient ischemic attacks (TIAs). These are more common in elderly people with psychosis related to dementia. Symbyax is not approved for these patients.
• Severe allergic reactions. Tell your doctor right away if you get red itchy welts (hives) or a rash alone or with fever and joint pain, while taking Symbyax. Call your doctor right away if you become severely ill and have swelling of your face, eyes or mouth, and/or trouble breathing.
• Neuroleptic malignant syndrome (NMS). This is a rare but very serious condition that can happen in people who take certain medicines for mental health problems, including Symbyax. NMS can cause death and must be treated in a hospital. The symptoms include high fever; excessive sweating; rigid muscles; confusion; and changes in breathing, heartbeat, and blood pressure. Call your doctor right away if you become severely ill and have some or all of these symptoms.
• High blood sugar (hyperglycemia). High blood sugar can occur if you have diabetes already or even if you have never had diabetes. In rare cases, this could lead to ketoacidosis (build up of acid in the blood due to ketones), coma, or death. Your doctor should do lab tests to check your blood sugar before you start taking Symbyax and during treatment. In people who do not have diabetes, sometimes high blood sugar goes away when Symbyax is stopped. People with diabetes and some people who did not have diabetes before taking Symbyax need to take medicine for high blood sugar even after they stop taking Symbyax. If you have diabetes, follow your doctor's instructions about how often to check your blood sugar while taking Symbyax.
  Call your doctor if you have any of these symptoms of high blood sugar (hyperglycemia) while taking Symbyax:
• feel very thirsty
• need to urinate more than usual
• feel very hungry
• feel weak or tired
• feel sick to your stomach
• feel confused, or your breath smells fruity.
• High cholesterol and triglyceride levels in the blood (fat in the blood). These have been observed in patients treated with Symbyax, especially in teenagers (13-17 years old) who received olanzapine, one of the components of Symbyax. Symbyax is not approved for use in patients less than 18 years old. You may not have any symptoms, so your doctor should do blood tests to check your cholesterol and triglyceride levels before you start taking Symbyax and during treatment.
• Increase in weight (weight gain). Weight gain is very commonly seen in patients who take Symbyax. Teenagers (13-17 years old) who received olanzapine, one of the components of Symbyax, were more likely to gain weight and to gain more weight than adults. Symbyax is not approved for use in patients less than 18 years old. Some patients may gain a lot of weight while taking Symbyax, so your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising.
• Tardive dyskinesia. This condition causes body movements that keep happening and that you cannot control. These movements usually affect the face and tongue. Tardive dyskinesia may not go away, even if you stop taking Symbyax. It may also start after you stop taking Symbyax. Tell your doctor if you get any body movements that you cannot control.
• Serotonin syndrome. This is a condition that can be life threatening. Call your doctor right away if you become severely ill and have some or all of these symptoms: agitation; hallucinations; problems with coordination; racing heart beat; over-active reflexes; fever; nausea, vomiting, and diarrhea.
• Abnormal bleeding. Tell your doctor if you notice any increased or unusual bruising or bleeding while taking Symbyax, especially if you take one of these medications: the blood thinner warfarin (Coumadin, Jantoven), a nonsteroidal anti-inflammatory drug (NSAID), aspirin.
• Low salt (sodium) levels in the blood (hyponatremia). Call your doctor right away if you become severely ill and have some or all of these symptoms: headache, feel weak, confusion, problems concentrating, memory problems, feel unsteady.
• Decreased blood pressure when you change position, with symptoms of dizziness, fast or slow heart beat, or fainting.
• Decreases in white blood cells (infection fighting cells) have been reported in some patients taking antipsychotic agents, including SYMBYAX. Patients with a history of a significant decrease in white blood cell (WBC) count or who have experienced a low WBC count due to drug therapy should have their blood tested and monitored during the first few months of therapy.
• Seizures.
• Trouble swallowing.
• Problems with control of body temperature. You could become very hot, for instance when you exercise a lot or stay in an area that is very hot. It is important for you to drink water to avoid dehydration. Call your doctor right away if you become severely ill and have some or all of these symptoms of dehydration: sweating too much or not at all, dry mouth, feeling very hot, feeling thirsty, not able to produce urine.

Who should not take Symbyax?

• Do not take Symbyax if you already take a Monoamine Oxidase Inhibitor (MAOI) or if you stopped taking an MAOI in the last 2 weeks. Do not take an MAOI within 5 weeks of stopping Symbyax. People who take Symbyax close in time to an MAOI can have serious and life-threatening side effects, with symptoms including: high fever, continued muscle spasms that you cannot control, rigid muscles, changes in heart rate and blood pressure that happen fast, confusion, unconsciousness. Ask your doctor or pharmacist if you are not sure if your medicine is an MAOI.
