What is Latuda?
Latuda (lurasidone) is used as an antipsychotic drug which works by changing the effects of chemicals in the brain.
Latuda uses (uses of Latuda)
Latuda is used in the treatment schizophrenia in adults and in teenagers who are at least 13 years old.
It is also used to treat some episodes of depression in adults with bipolar disorder (manic depression).
The uses of Latuda (Latuda uses) vary vastly and no one can ever boast of knowing all its uses.
Latuda is has not yet been approved for use in psychotic conditions related to dementia. Lurasidone may also increase the risk of death in older adults who have dementia-related conditions.
Some young people have thoughts about suicide when they start taking medicine to treat depression. Stay alert to changes in your mood and/or symptoms. You should report any new or worsening symptoms to your doctor.
Before you start taking Latuda, tell your doctor if you have a liver disease, kidney disease, a history of heart attack or stroke, heart disease, high blood pressure, heart rhythm problems, high cholesterol or triglycerides, low white blood cell (WBC) counts, seizures, diabetes, Parkinson's disease, trouble swallowing, or a history of breast cancer or some suicidal thoughts.
Some other medicines can interact with lurasidone and should not be used at the same time. Tell every one of your healthcare providers about all medicines you use now, and any medicine you start and/or stop using.
While you are still taking Latuda, you may be more sensitive to simple temperature extremes such as very hot or cold conditions. You should avoid getting too cold, or becoming overheated and/or dehydrated. Drink a lot of fluids, especially in hot weather and when you are doing exercise. It is very easy to become dangerously overheated and dehydrated while you are taking this medicine.
Latuda may also impair your thinking or reactions so you should be very careful if you drive or do anything that requires you to be alert. Avoid getting up too fast from your sitting or lying position, or you may feel dizzy and eventually fall. Get up relatively slowly and steady yourself to prevent a fall.
Drinking alcohol can increase certain side effects of Latuda (lurasidone). Stop using this medicine and get to your doctor at once if you have very stiff (rigid) muscles, high fever, sweating, the feeling like you might pass out, confusion, very fast or pounding heartbeats, tremors, or twitching or uncontrollable movements of the eyes, lips, face, tongue, arms, or legs.

The most common adverse events that have been noted and reported so far included somnolence, akathisia, extrapyramidal symptoms, and nausea (feeling as to vomit).
Common: Increased weight, increase in appetite, decreased appetite
Frequency not reported: total increase in blood sugar levels
In uncontrollable long-term schizophrenia trials this drug was actually associated with a mean increase in glucose from baseline of 1.8 mg/dL at 24 weeks, 0.8 mg/dL at some 36 weeks, and 2.3 mg/dL at 52 weeks. Similar results were also observed in bipolar depression studies. The proportions of lurasidone-treated patients with a 7% or greater increase in body weight was at 4.8% (compared with 3.3% for placebo). The pooled data from short-term trials showed a mean weight gain of 0.43 kg in the lurasidone-treated patients (compared with the -0.2 kg in placebo).
- Very common: Nausea
- Common: Vomiting, salivary hypersecretion, dyspepsia, dry mouth, diarrhea
- Uncommon: Abdominal pains (stomach ache), and/or diarrhea

ECG measurements that were taken at various points during clinical trials found no QT prolongations exceeding 500 milliseconds (ms) including a subset of patients defined as having an increased cardiac risk. In a dedicated QT study in the clinically stable patients with the schizophrenia or schizoaffective disorder (n=87), the total maximum mean increase in QTc was at 0.36 ms and 1.69 ms for a 120 mg and 600 mg of the dose, respectively. However, no patient experienced a QTc increase of greater than 60 ms from baseline and no patient experienced a QTc greater than 500 ms.
