Compare Abilify vs. Zyprexa

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Aripiprazole (Abilify) and Olanzapine (Zyprexa) are both atypical antipsychotics used to treat mental health conditions like schizophrenia and bipolar disorder. Aripiprazole is available in various forms, including tablets, solutions, and orally disintegrating tablets, and can be used in children as young as 6 years old for certain conditions. Olanzapine is also available in multiple forms, including tablets and injections, and is used in children 13 years and older. One key difference is that aripiprazole is less likely to cause weight gain compared to olanzapine, which is known for causing significant weight gain and higher blood sugar levels. Both medications can cause movement problems and restlessness, but olanzapine can also cause anticholinergic side effects like trouble urinating. Both medications can cause serious side effects like neuroleptic malignant syndrome and have warnings about use in older adults with dementia-related psychosis.
