By Miriatu

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.

Important information

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.

Before taking this medicine

You are advised not use Latuda if you are allergic to lurasidone.

Some other medicines can interact with lurasidone and should not be used at the same time. Your doctor may also need to change your treatment plan if you are using certain other medicines including:

  • antifungal medicine such as the ketoconazole or voriconazole;
  • antibiotics such as clarithromycin or rifampin;
  • antivirals such as ritonavir;
  • St. John's wort; or
  • Any seizure medicine such as carbamazepine or phenytoin.

Latuda has not been approved for use in psychotic conditions related to dementia. Latuda may also increase the risk of death in older adults (geriatric) with dementia-related conditions.

Some young people can have thoughts about suicide when first taking medicine to treat depression. Your doctor should always check your progress at regular visits. Your family, friends or other caregivers should also be alert to changes in your mood or symptoms.

Taking antipsychotic medication during the last 3 months of pregnancy may however cause problems in the newborn, such as some withdrawal symptoms, breathing complications, feeding problems, tremors, fussiness, and limp or stiff muscles. However, you may have some withdrawal symptoms or other problems if you stop taking your medicine during pregnancy. Ifyou do become pregnant while taking Latuda, do not stop taking the drug without your doctor's advice.

If you are pregnant and meet medical experts, your name may be listed on a pregnancy registry (register). This is to keep track of the outcome of the pregnancy and to evaluate any effects of lurasidone on your baby.

It is not yet known whether lurasidone passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are also a nursing mother.
