Uzedy injection is an extended-release injectable suspension used in adults to treat schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions).

Uzedy belongs to a class of medications called atypical antipsychotics. Risperidone works by changing the activity of certain natural substances in the brain.

The Uzedy product label carries a Boxed Warning for increased risk of death in elderly patients with dementia-related psychosis. It is not approved for use in older adults with dementia-related psychosis.

Warnings and precautions associated with Uzedy include increased incidence of cerebrovascular adverse reactions in elderly patients with dementia-related psychosis; neuroleptic malignant syndrome; tardive dyskinesia; metabolic changes; hyperprolactinemia; orthostatic hypotension and syncope; leukopenia, neutropenia, and agranulocytosis; potential for cognitive and motor impairment; seizures; and priapism.

While you are taking this medicine, you may be more sensitive to temperature extremes such as very hot or cold conditions. Avoid getting too cold, or becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking this medication.

Uzedy may impair your thinking or reactions and cause drowsiness. Be careful if you drive or do anything that requires you to be alert. Drinking alcohol can increase certain side effects of this medicine.

If you are breastfeeding, tell your doctor if you notice drowsiness, irregular growth, tremors and abnormal muscle movements in the nursing baby.

Use Uzedy injection exactly as prescribed by your doctor. If you already use other antipsychotic medication, you may need to keep using it for a short time. Do not change your dose or dosing schedule without your doctor's advice.

You may need to take risperidone by mouth (in pill or liquid form) before you start receiving Uzedy injections. Follow your doctor's dosing instructions very carefully.

Your doctor will need to check your progress on a regular basis and you may need other medical tests.

Uzedy is administered by subcutaneous injection once every month or once every 2 months. To start Uzedy, switch from taking oral daily risperidone using the dosing schedule below. Start with either a once monthly injection or a once every 2 month injection, starting the day after the last dose of oral therapy.

Do not drink alcohol. Dangerous side effects could occur.

Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.

Avoid driving or hazardous activity until you know how this medicine will affect you. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Dizziness or drowsiness can cause falls, accidents, or severe injuries.

Get emergency medical help if you have signs of an allergic reaction to Uzedy: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

High doses or long-term use of risperidone can cause a serious movement disorder that may not be reversible. The longer you use Uzedy, the more likely you are to develop this disorder, especially if you are a woman or an older adult.

Uzedy injection may cause serious side effects. Call your doctor at once if you have:

• uncontrolled muscle movements in your face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement);

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Using Uzedy injection with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

Sometimes it is not safe to use certain medicines at the same time. Some drugs can affect your blood levels of other drugs you use, which may increase side effects or make the medicines less effective.

Tell your doctor about all your current medicines. Many drugs can affect Uzedy, especially:

• methylphenidate;

• clozapine; or

• blood pressure medications.

This list is not complete and many other drugs may interact with risperidone. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
