Post-Injection delirium/sedation syndrome, a collection of signs and symptoms consistent with olanzapine overdose has been reported following injections of the extended-release IM suspension. Events occurred in less than 0.1% of injections and in approximately 2% of patients receiving injections for up to 46 months. Onset of events ranged from soon after injection to greater than 3 hours later. The majority of patients were hospitalized and some required supportive care, including intubation. Two deaths have been reported occurring 3 to 4 days after receiving the appropriate dose of the extended-release IM suspension. In these patients, very high olanzapine blood levels were reported after death. A study undertaken to determine the cause of the elevated drug levels in these 2 deaths provides inconclusive results. As reported in a 3-23-2015 drug safety communication issued by the US Food and Drug Administration, a study in animals found much of the drug level increases could have occurred after death, but the possibility that the deaths were caused by a rapid, but delayed entry of the drug in to the bloodstream could not be ruled out.

Akathisia most commonly occurred with oral doses of 15 mg/day; akathisia events included akathisia and hyperkinesia.

Dyskinetic events included buccoglossal syndrome, choreoathetosis, dyskinesia, and tardive dyskinesia.

Dystonic events included dystonia, generalized spasm, neck rigidity, oculogyric crisis, opisthotonos, and torticollis.

Parkinsonism/parkinsonism events most commonly occurred with oral doses of 15 mg/day and included akinesia, cogwheel rigidity, extrapyramidal syndrome, hypertonia, hypokinesia, masked facies, and tremor.

Sedation most commonly occurred in adolescent patients given oral doses at least 2.5 mg/day over 3 weeks; sedation included hypersomnia, lethargy, sedation, and somnolence.

Somnolence and tremor most commonly occurred with oral doses given with lithium or valproate.

Collective data gathered from 17 placebo-controlled clinical studies (n=5106) involving the use of atypical antipsychotic agents, including olanzapine, for the treatment of behavioral disorders in the elderly patient with dementia showed a risk of death 1.6 to 1.7 times greater in the drug treated patient than in the placebo treated patient. The average length of duration for the trials was 10 weeks with the cause of death in the majority of cases, though not all, reported as either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Olanzapine is not approved by the FDA for use in the treatment of behavioral disorders in elderly patients with dementia.

Olanzapine appears to have a greater association than some other atypical antipsychotics for increasing glucose levels. Mean increases of up to 15 mg/dL have been reported. The differences in mean changes in serum glucose were higher in patients with evidence of glucose dysregulation at baseline. In an analysis of patients who completed 9 to 12 months of therapy, the rate on increase in mean blood glucose slowed after approximately 6 months.

Clinically significant alterations in lipids have been observed including serum triglyceride elevations greater than 500 mg/dL. In long-term studies of at least 48-weeks in adults, increased from baseline in mean fasting cholesterol, LDL, triglycerides were 5.6 mg/dL, 2.5 mg/dL, and 18.7 mg/dL, respectively. Mean increases in fasting lipid values (total cholesterol, LDL and triglycerides) were greater in patients without evidence of lipid dysregulation at baseline.

In 13 placebo-controlled monotherapy trials, olanzapine-treated patients gained an average of 2.6 kg compared to an average 0.3 kg weight loss in placebo patients; 22.5% gained at least 7% of their baseline weight, 4.2% at least 15% of their baseline (compared to 3% and 0.3% in placebo). Clinically significant weight gain was observed across all baseline BMIs. With longer term exposure (at least 24 weeks), weight gain of 7%, 15%, or 25% or more were reported in 89.4%, 55.3%, and 29.1%, respectively. Weight gain and increased appetite were reported in 40.6%, 7.1%, and 2.5% of adolescents receiving this drug in short term treatment (approximately 22 days), respectively.
