Depression in later life frequently coexists with other medical illnesses and disabilities. In addition, advancing age is often accompanied by loss of social support systems due to the death of a spouse or siblings, retirement, or relocation of residence. Because of changes in an elderly person's circumstances and the fact that elderly people are expected to slow down, doctors and family may miss the signs of depression. As a result, effective treatment gets delayed. Many seniors find themselves trying to cope with symptoms that could have been easily treated.
Depression tends to last longer in elderly adults. It doubles their risk of cardiac diseases and increases their risk of death from illness. At the same time, depression reduces an elderly person's ability to rehabilitate.
Studies of nursing home patients with physical illnesses have shown that the pres...
SYMBYAX
(olanzapine and fluoxetine hydrochloride) capsule for oral use
WARNING: SUICIDALITY AND ANTIDEPRESSANT DRUGS AND INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
Suicidality and Antidepressant Drugs — Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of Major Depressive Disorder (MOD) and other psychiatric disorders. Anyone considering the use of SYMBYAX or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. SYMBYAX is not approved for use in pediatric patients. [See WARNINGS AND PRECAUTIONS, Use in Specific Populations, and PATIENT INFORMATION].
Increased Mortality in Elderly Patients with Dementia-Related Psychosis — Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. SYMBYAX (olanzapine and fluoxetine HC1) is not approved for the treatment of patients with dementia-related psychosis [see WARNINGS AND PRECAUTIONS and PATIENT INFORMATION].
SYMBYAX (olanzapine and fluoxetine HC1 capsules) combines an atypical antipsychotic and a selective serotonin reuptake inhibitor, olanzapine (the active ingredient in Zyprexa, and Zyprexa Zydis) and fluoxetine hydrochloride (the active ingredient in Prozac, Prozac Weekly, and Sarafem).
Olanzapine belongs to the thienobenzodiazepine class. The chemical designation is 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b] [1,5]benzodiazepine. The molecular formula is C17H20N4S, which corresponds to a molecular weight of 312.44.
Fluoxetine hydrochloride is a selective serotonin reuptake inhibitor (SSRI). The chemical designation is (±)-N-methyl-3phenyl-3-[(α,α,α-trifluoro-p-tolyloxy]propylamine hydrochloride. The molecular formula is C17H18F3NO•HCl, which corresponds to a molecular weight of 345.79.
The chemical structures are:
![]() |
Olanzapine is a yellow crystalline solid, which is practically insoluble in water.
Fluoxetine hydrochloride is a white to off-white crystalline solid with a solubility of 14 mg/mL in water.
SYMBYAX capsules are available for oral administration in the following strength combinations:
| 3 mg/25 mg | 6 mg/25 mg | 6 mg/50 mg | 12 mg/25 mg | 12 mg/50 mg | |
| olanzapine equivalent | 3 | 6 | 6 | 12 | 12 |
| fluoxetine base equivalent | 25 | 25 | 50 | 25 | 50 |
Each capsule also contains pregelatinized starch, gelatin, dimethicone, titanium dioxide, sodium lauryl sulfate, edible black ink, red iron oxide, yellow iron oxide, and/or black iron oxide.
Get emergency medical help if you have any of these signs of an allergic reaction: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have any new or worsening symptoms such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
