Latuda (lurasidone) is an atypical antipsychotic medication that is approved by the FDA, and it is prescribed for treating schizophrenia and depressive episodes in bipolar I disorder. It comes in tablet form with varying dosages, to be taken once daily with food. Latuda works by altering the levels of serotonin and dopamine in the brain, chemicals involved in mood regulation. While effective, it may cause side effects ranging from mild allergic reactions to severe issues like neuroleptic malignant syndrome. It has significant interactions with certain drugs, foods, and supplements, notably strong inhibitors and inducers of the enzyme CYP3A4, and should not be taken with grapefruit.

Latuda Overview

Latuda (lurasidone) is a brand-name medication also available as a generic drug under the name lurasidone. It belongs to the class of drugs known as atypical antipsychotics, which are used to treat mental health conditions by adjusting the levels of neurotransmitters in the brain. Latuda is specifically approved for treating major depressive episodes associated with bipolar I disorder & schizophrenia. It is administered orally and is available in doses ranging from 20 to 120 mg.

Patients prescribed Latuda should take it once daily with at least 350 calories of food to ensure proper absorption. The starting dose usually depends on the treated condition—20 mg for bipolar depression and 40 mg for schizophrenia, potentially increasing based on therapeutic needs and patient tolerance. Latuda’s effectiveness in altering brain chemistry comes from its impact on serotonin and dopamine, which helps alleviate symptoms of schizophrenia and bipolar depression. However, it can take one to two weeks for the effects to become noticeable, and patients are advised to continue usage as prescribed by their doctor.

Side effects can vary from mild, such as sleepiness and nausea, to severe, including increased prolactin levels and the risk of stroke in older adults with dementia-related psychosis. Latuda can also interact with a wide range of substances, including strong CYP3A4 inhibitors like ketoconazole, which can increase its blood levels, and inducers like carbamazepine, which can decrease its efficacy. Careful monitoring and consultation with healthcare providers are essential to manage these interactions and side effects effectively.

    • Verelan (verapamil)

Frequently Asked Questions

Can Latuda cause sexual dysfunction?

Yes, Latuda can cause sexual dysfunction. Males who take Latuda may experience erectile dysfunction, which is difficulty in getting or keeping an erection. This can be due to a condition called hyperprolactinemia, where there is a high level of the hormone prolactin in the body. Hyperprolactinemia is a potential side effect of Latuda. For females, there were no reports in clinical trials of this medication causing sexual dysfunction. However, it’s crucial to note that a raised amount of prolactin, which can be a side effect of Latuda, might lead to sexual dysfunction in females. High levels of prolactin are thought to decrease vaginal secretions and lubrication, which can cause sexual dysfunction.

Will I feel high while using Latuda?

No, taking Latuda tablets shouldn’t cause a high feeling. However, feeling high might be a symptom of bipolar mania, a period in bipolar disorder where you feel extremely energized and excited. If you are concerned about feeling high after taking Latuda, talk to your doctor. They can monitor you more closely for other symptoms of bipolar mania.

Is Latuda a Narcotic?

No, Latuda is not a narcotic. It belongs to a class of drugs known as atypical antipsychotics, which are medications that work in a similar way to manage certain mental health conditions. Narcotics, on the other hand, are a type of strong pain reliever, also referred to as opioids. Atypical antipsychotics, such as Latuda, are used as mood stabilizers to help treat shifts in mood, such as those seen in schizophrenia and bipolar disorder.

Why avoid getting too hot while using Latuda?

While taking Latuda, it’s important to avoid getting too hot because the medication may reduce your ability to regulate your body temperature. This reduced ability can increase your risk of developing hyperthermia, a condition where your body temperature becomes dangerously high. To prevent this, take steps to stay cool and avoid environments that might lead to overheating. If you have questions about how to safely manage your body temperature while using Latuda, it’s a good idea to discuss them with your doctor.
