1. What is TRD?

TRD is a form of depression that is more difficult to treat. A person may have TRD if during an episode of depression, he or she has had little or no response to treatment with 2 different antidepressants. This may happen even when the person takes the right dose for the right amount of time. In clinical studies of people with depression, nearly 1 person in 3 may have TRD.

2. What are the symptoms of TRD?

People with TRD may have the same symptoms as people who have depression. The only difference for people with TRD is that their depression symptoms continue, even after repeated attempts to treat them. View an expanded list of depression symptoms.

3. How is TRD treated?

There are several different forms of treatment that your healthcare professional may recommend to treat your TRD. These kinds of treatment may include medication with an antidepressant, like Symbyax, lifestyle changes, and therapy.

To determine if you have TRD and which forms of treatment are right for you, talk with a healthcare professional.

4. What is bipolar I depression?

Bipolar I depression is just one phase of bipolar I disorder, a condition that causes one to have dramatic mood swings. What makes bipolar I depression different from "regular" depression (major depressive disorder, or MDD) is that people with bipolar I depression have had a manic episode in the past. People with "regular" depression have never experienced a manic episode. View the entire list of manic and depressive symptoms of bipolar I disorder.

5. How is bipolar I depression treated?

The treatment program for bipolar I depression can vary for each individual. In general, a combination of treatment options is used, including medication, counseling, education, and more. To find out if you have bipolar I depression and learn more about what treatment options are best for you, talk to your healthcare professional.

6. What is Symbyax?

Symbyax is the first antidepressant approved by the FDA for acute treatment of TRD and bipolar I depression in adults. Symbyax is 1 pill that contains 2 medicines. These 2 medicines work together to help relieve TRD and bipolar I depression. Depression is believed to be linked to 3 naturally occurring substances in the body–serotonin, norepinephrine, and dopamine. Symbyax works on all 3.

7. How can I find out if Symbyax is right for me?

To find out if Symbyax could work for you, talk to your healthcare professional. Before taking Symbyax, it's important that you provide your healthcare professional with information about your health history and a list of medications you have recently taken or are currently taking. This list should include prescription medications, non-prescription medications, vitamins, and herbal supplements. Learn more about what to tell a healthcare professional to find out if Symbyax is right for you, and who should not take Symbyax.

8. What are the most common side effects of Symbyax?

All medicines can cause side effects. Tell your doctor about any side effect that bothers you or won't go away. Some common, possible side effects of Symbyax are:

Tiredness

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:

Antidepressants may increase suicidal thoughts or behaviors in some children, adolescents and young adults especially within the first few months of treatment or when changing the dose. No increased risk has been shown for adults over age 24, and risk decreased for those over age 65. All patients starting therapy should be monitored appropriately and observed closely for new or worsening depression symptoms, suicidal thoughts or behavior, or unusual changes in behavior. Symbyax is not approved for children and adolescents.
Elderly people with psychosis related to dementia (a brain disorder that lessens the ability to remember, think, and reason) are at increased risk of death when taking certain mental health medicines (such as Symbyax) compared with a sugar pill. Symbyax is not approved for these patients.

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.
