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
