Risperdal vs. Latuda
See how Risperdal and Latuda compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Risperdal (risperidone) and Latuda (lurasidone) are both atypical antipsychotics, but Risperdal is approved for autism-related irritability while Latuda is approved specifically for bipolar depression.
Risperdal comes in tablets, an oral solution, and a fast-dissolving tablet, while Latuda is a once-daily tablet that must be taken with a substantial meal to absorb properly.
Both drugs carry a boxed warning about increased mortality in elderly patients with dementia-related psychosis and are not approved for that use.

Risperdal vs. Latuda Indications
Risperdal
Risperdal is FDA-approved for schizophrenia in adults and teens, for manic or mixed episodes of bipolar I disorder, and for irritability tied to autistic disorder in children. It is sometimes used off-label for treatment-resistant OCD or tic disorders like Tourette syndrome, though these are not FDA-approved uses.
Schizophrenia in adults and adolescents 13 and older
Acute manic or mixed episodes of bipolar I disorder
Irritability associated with autistic disorder in children
Latuda
Latuda is FDA-approved for schizophrenia in adults and adolescents, and for major depressive episodes linked to bipolar I disorder in adults and in children as young as 10. It is not approved for manic episodes or for irritability associated with autism.
Schizophrenia in adults and adolescents 13 and older
Bipolar depression in adults, alone or with lithium/valproate
Bipolar depression in children and adolescents 10 to 17
Risperdal vs. Latuda Pros and Cons
Risperdal
Risperidone has been prescribed since 1993, giving clinicians decades of real-world experience with its effects and interactions. It comes in more dosage forms than Latuda, but carries a comparatively higher risk of prolactin-related side effects and movement symptoms at higher doses.
Pros
Available as a tablet, oral solution, and orally disintegrating tablet, plus a long-acting injectable
Longest track record of any atypical antipsychotic, approved since 1993
Only one of these two approved for irritability in pediatric autistic disorder
Cons
Higher risk of prolactin elevation, which can cause sexual side effects or missed periods
More weight gain and larger changes in blood sugar and cholesterol than Latuda in trials
Movement-related side effects like parkinsonism are more common at higher doses
Latuda
Latuda's clinical trials show smaller effects on weight, blood sugar, and cholesterol than risperidone, which matters for people managing metabolic risk. Its need for a substantial meal and its high brand-name price are practical trade-offs against that cleaner metabolic profile.
Pros
Smaller effects on weight, blood sugar, and cholesterol than risperidone in clinical trials
Specifically approved for depressive episodes of bipolar I disorder, a use Risperdal lacks
No initial titration needed for adults; the starting dose is already in the effective range
Cons
Must be taken with at least 350 calories of food or the dose won't absorb properly
Brand-name cost can run $1,400 to $1,862 per month without insurance
Not approved for manic episodes of bipolar disorder or for autism-related irritability
