Olanzapine/fluoxetine
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 as well as treatment-resistant depression.[1]

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.[2]
Olanzapine/fluoxetine, or other antidepressant/antipsychotic combinations, are sometimes prescribed off-label for anxiety disorders,[3] eating disorders,[4] obsessive–compulsive disorder (OCD),[5] and posttraumatic stress disorder (PTSD).[6]
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.[7]
Olanzapine is correlated with an increase in blood sugar. Patients with diabetes, or those at risk for developing it, require careful monitoring.[7]
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]
