Latuda (lurasidone) is a prescription medication approved by the FDA to treat schizophrenia in adults and adolescents, and to treat depressive episodes in adults with bipolar I disorder. It is an atypical antipsychotic that works by balancing certain brain chemicals, specifically dopamine and serotonin, to reduce symptoms like hallucinations, delusions, and low mood. Latuda is not used for all phases of bipolar disorder—it is specifically approved for the depressed phase, not for mania.
What Is Latuda Used For Schizophrenia Bipolar?
Latuda has two main FDA-approved uses. The first is schizophrenia, a chronic mental health condition that affects how a person thinks, feels, and behaves. The second is bipolar depression, which is the low mood phase of bipolar I disorder. In schizophrenia, Latuda treats both positive symptoms like hallucinations and delusions, and negative symptoms like lack of motivation or social withdrawal. In bipolar depression, it helps lift the depressive mood that can last for weeks or months.
It is important to understand that Latuda is not approved for manic episodes. Mania is the high-energy, sometimes risky phase of bipolar disorder. If someone is experiencing mania, a different medication is typically needed. Latuda also is not approved for the maintenance phase of bipolar disorder, meaning it has not been studied or approved for long-term prevention of mood episodes.
How Does Latuda Work in the Brain?
Latuda belongs to a class of drugs called atypical antipsychotics. These medications work by blocking certain receptors in the brain. Specifically, Latuda blocks dopamine D2 receptors and serotonin 5-HT2A receptors. Dopamine is a neurotransmitter linked to reward, movement, and psychotic symptoms. Serotonin affects mood, appetite, and sleep.
By blocking dopamine, Latuda reduces the overactivity that is believed to cause hallucinations and delusions in schizophrenia. By blocking serotonin, it helps regulate mood, which is why it works for bipolar depression. Unlike older antipsychotics, Latuda also has a high affinity for serotonin 5-HT7 receptors, which some researchers believe contributes to its antidepressant and cognitive benefits. However, the exact way this works is still being studied.
One thing that makes Latuda different from many other antipsychotics is that its absorption is highly dependent on food. Taking Latuda with at least 350 calories of food can roughly double its absorption compared to taking it on an empty stomach. This is a practical detail that matters for anyone taking this medication.
What Are the Common Side Effects of Latuda?
Like all antipsychotics, Latuda carries a risk of side effects. The most common ones include sleepiness, restlessness, nausea, and akathisia—a feeling of inner restlessness that makes it hard to sit still. These side effects are most noticeable when starting the medication or when the dose is increased.
Some people experience metabolic side effects such as weight gain or changes in blood sugar and cholesterol. However, research suggests Latuda may cause less weight gain than some other atypical antipsychotics like olanzapine or quetiapine. Still, any person taking Latuda should have their weight and metabolic markers monitored regularly by their doctor.
There are also more serious risks to be aware of. Latuda can cause tardive dyskinesia, a condition of uncontrollable repetitive movements, especially of the face and tongue. This is rare but can be permanent. Another serious risk is neuroleptic malignant syndrome, a rare but life-threatening reaction that causes fever, muscle stiffness, and confusion. Anyone experiencing these symptoms needs emergency medical care immediately.
How Is Latuda Taken and Dosed?
Latuda comes as a tablet that is taken once daily, typically in the evening. The dose for schizophrenia in adults usually starts at 40 mg per day, and the dose for bipolar depression usually starts at 20 mg per day. Doctors may adjust the dose based on how well the medication works and how the person tolerates it.
For schizophrenia, the recommended dose range is 40 to 160 mg per day. For bipolar depression, the range is 20 to 120 mg per day. The medication must be taken with food—at least 350 calories—to ensure adequate absorption. Taking it without food can significantly reduce the amount of drug that reaches the bloodstream, which can make the medication less effective.
Latuda is also available in an injectable form for short-term use in certain situations, but the oral tablet is the standard form. It is important to follow the prescribing doctor’s instructions exactly. Stopping Latuda suddenly can cause withdrawal-like symptoms or a return of the underlying condition, so any dose changes should be done under medical supervision.
What Should You Discuss With Your Doctor Before Starting Latuda?
Before starting Latuda, tell your doctor about all other medications you take, including over-the-counter drugs and supplements. Latuda can interact with certain medications, particularly those that affect liver enzymes called CYP3A4. Strong inhibitors of this enzyme, like ketoconazole or certain HIV medications, can raise Latuda levels dangerously high. Strong inducers, like carbamazepine or St. John’s Wort, can lower Latuda levels and make it less effective.
Latuda is not recommended during pregnancy unless the potential benefit clearly outweighs the risk. Infants exposed to antipsychotics in the third trimester may experience withdrawal symptoms or abnormal muscle movements after birth. If you are pregnant, planning to become pregnant, or breastfeeding, discuss this with your doctor before starting the medication.
Older adults with dementia-related psychosis should not take Latuda because antipsychotics increase the risk of death in this population. The FDA has issued a black box warning about this risk. Latuda is also not approved for use in children for bipolar depression, and its safety in children for schizophrenia is limited to adolescents aged 13 to 17.
How Effective Is Latuda Compared to Other Antipsychotics?
Clinical trials have shown that Latuda is more effective than placebo for both schizophrenia and bipolar depression. In schizophrenia, it reduces positive and negative symptoms significantly compared to placebo. In bipolar depression, studies have shown that Latuda improves mood scores and increases the likelihood of achieving remission from depression.
Compared to other antipsychotics, Latuda’s profile is somewhat distinctive. It tends to cause less weight gain and fewer metabolic issues than older atypical antipsychotics like olanzapine. However, it has a higher rate of akathisia and nausea compared to some alternatives. The choice between Latuda and other medications depends on a person’s specific symptoms, side effect tolerance, and medical history.
Some research suggests that Latuda may have a more favorable cognitive profile than some other antipsychotics, but this is an area of ongoing study and not firmly established. No antipsychotic works for everyone, and it may take trying more than one medication to find the right fit.
Frequently Asked Questions
Can Latuda be taken alone for bipolar disorder?
Yes, Latuda can be used alone for bipolar depression, but many people take it with a mood stabilizer like lithium or valproate. Your doctor will decide based on your specific symptoms and history.
Is Latuda addictive?
No, Latuda is not considered addictive in the way that opioids or benzodiazepines are. However, stopping it suddenly can cause withdrawal-like symptoms, so it should be tapered under medical supervision.
How long does Latuda take to work?
Some people notice improvement in symptoms within one to two weeks, but full effects may take four to six weeks. Consistent daily use with food is essential for the medication to work properly.
Can Latuda cause weight gain?
Yes, Latuda can cause weight gain, but clinical data suggests it may cause less weight gain than some other atypical antipsychotics. Weight should be monitored regularly while taking this medication.
