This medication is used to treat certain mental/mood disorders (such as schizophrenia, depression associated with bipolar disorder). Lurasidone belongs to a class of drugs known as atypical antipsychotics. It works by helping to restore the balance of certain natural substances in the brain.

Read the Medication Guide provided by your pharmacist before you start taking lurasidone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually once daily. The dosage is based on your medical condition, response to treatment, age, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Keep taking this medication exactly as prescribed, even if you are feeling better and thinking more clearly. Do not increase your dose or take this drug more often than prescribed. Your symptoms will not improve any faster, and your risk of side effects will increase. Do not stop taking this medication without consulting your doctor.

This medication may cause a serious drop in blood pressure, especially when starting this medication. Dizziness and lightheadedness can increase the risk of falling. Get up slowly when rising from a sitting or lying position.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including:

Rarely, this medication may cause face/muscle twitching and uncontrollable movements (tardive dyskinesia). In some cases, this condition may be permanent. Tell your doctor right away if you develop any uncontrollable movements such as lip smacking, mouth puckering, tongue thrusting, chewing, or unusual arm/leg movements.

This drug may rarely make your blood sugar rise, which can cause or worsen diabetes. Weight gain from this drug may increase the risk of this side effect. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

This medication may also cause a rise in your blood fat levels (cholesterol and triglycerides). These increases, along with diabetes and weight gain, may increase your risk for developing heart disease. Discuss the risks and benefits of treatment with your doctor.

In rare cases, lurasidone may increase your level of a certain substance made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor right away.

Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.
