Key Takeaways
Abilify and Risperdal are both atypical antipsychotics approved for schizophrenia and bipolar I disorder, but they act on dopamine differently and cause different side effects.
Abilify is a partial dopamine agonist and is less likely to raise prolactin, while Risperdal tends to cause more sedation and prolactin-related effects.
Both drugs carry a boxed warning against use in elderly patients with dementia-related psychosis, and neither is approved for that use.

Abilify vs. Risperdal Pros and Cons
Abilify
Abilify's partial dopamine agonism makes it less likely to raise prolactin than many antipsychotics, though it tends to be more activating. Generic aripiprazole is inexpensive, but brand-name Abilify and its long-acting injectable forms cost significantly more.
Pros
Less likely to raise prolactin than Risperdal
Also approved as an add-on for depression
Available as a once-monthly long-acting injectable
Tablet with digital sensor option (Abilify Mycite)
Cons
More likely to cause akathisia and restlessness
Can be activating, which may worsen insomnia or anxiety
More tablet strengths to manage if adjusting dose
Brand-name price runs roughly $580 to $890 per month before insurance and savings programs
Risperdal
Risperdal's stronger dopamine blockade can cause more sedation and a higher risk of prolactin-related effects than Abilify, though it has one of the longest track records among atypical antipsychotics. Its generic form and lower brand price make it a more budget-friendly option for many patients.
Pros
Long track record, approved for autism-related irritability since 2006
May cause less activation and insomnia than Abilify for some patients
Available in tablet, dissolving tablet, and liquid forms
Brand-name price is roughly $185 to $625 per month before insurance, generally less than Abilify
Cons
Higher risk of prolactin elevation, which can cause menstrual changes or breast enlargement
More sedating, with higher rates of somnolence than Abilify
Orthostatic hypotension risk, especially during initial titration
Higher rate of parkinsonism-type movement side effects
