Olanzapine/fluoxetine (trade name Symbyax, created by Eli Lilly and Company) is a fixed-dose combination medication containing olanzapine (Zyprexa), an atypical antipsychotic, and fluoxetine (Prozac), a selective serotonin reuptake inhibitor (SSRI). Olanzapine/fluoxetine is primarily used to treat the depressive episodes of bipolar I disorder^[2] as well as treatment-resistant depression.^[1]^[3]

Medical uses

Olanzapine/fluoxetine was approved by the U.S. Food and Drug Administration (FDA) to treat the depressive episodes of bipolar I disorder in 2003.^[1] In 2009, it was granted approval for the treatment of treatment-resistant depression.^[4]

Olanzapine/fluoxetine, or other antidepressant/ antipsychotic combinations, are sometimes prescribed off-label for anxiety disorders,^[5] eating disorders,^[6] obsessive–compulsive disorder (OCD),^[7] and posttraumatic stress disorder (PTSD).^[8]

Side effects

Possible side effects of olanzapine/fluoxetine include all those of the two component drugs: olanzapine (side effects) and fluoxetine (side effects). Common side effects include suicidal thoughts, increased appetite, weight gain, drowsiness, fatigue, dry mouth, swelling, tremor, blurred vision, and difficulty concentrating.^[1]

Olanzapine/fluoxetine could produce a severe allergic reaction and should not be used if the patient has previously experienced an allergic reaction to either fluoxetine or olanzapine.^[9]

Olanzapine is correlated with an increase in blood sugar. Patients with diabetes, or those at risk for developing it, require careful monitoring.^[9]

In rare cases, olanzapine/fluoxetine may cause neuroleptic malignant syndrome.^[1]

Like other SSRIs, olanzapine/fluoxetine carries a boxed warning stating that it could increase the risk of suicidal thoughts and behaviors in patients aged 24 and under. The warning also states that olanzapine/fluoxetine may increase the risk of death in elderly patients with dementia-related psychosis.^[1]
