Zyprexa Relprevv

Generic name: olanzapine pamoate

What is Zyprexa Relprevv?

Zyprexa Relprevv is a long-acting prescription medicine given by injection and used to treat schizophrenia in adults. The symptoms of schizophrenia include:

  • hearing voices
  • seeing things that are not there
  • having beliefs that are not true
  • being suspicious or withdrawn

Some of your symptoms of schizophrenia may improve with treatment with Zyprexa Relprevv. If you do not think you are getting better, call your doctor.

It is not known if Zyprexa Relprevv is safe and effective in children under 18 years of age.

What is the most important information I should know about Zyprexa Relprevv?

Before you receive Zyprexa Relprevv treatment you must:

  • understand the risks and benefits of Zyprexa Relprevv treatment. Your doctor will talk to you about the risks and benefits of Zyprexa Relprevv treatment.
  • register in the Zyprexa Relprevv Patient Care Program. You must agree to the rules of the Zyprexa Relprevv Patient Care Program before you register.

Zyprexa Relprevv may cause serious side effects, including:

  1. Post-injection Delirium Sedation Syndrome (PDSS).
  2. Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis).
  3. High blood sugar (hyperglycemia).
  4. High fat levels in your blood (increased cholesterol and triglycerides), especially in teenagers age 13 to 17.
  5. Weight gain, especially in teenagers age 13 to 17.

These serious side effects are described below.

1. Post-injection Delirium Sedation Syndrome (PDSS). PDSS is a serious problem that can happen after you get a Zyprexa Relprevv injection if the medicine gets in your blood too fast. This problem usually happens within 3 hours after you receive Zyprexa Relprevv. If the medicine gets in your blood too fast, you may have some of the following symptoms:

  • feel more sleepy than usual
  • feel dizzy
  • feel confused or disoriented
  • trouble talking or walking
  • muscles feel stiff or shaking
  • feel weak
  • feel grouchy or angry
  • feel nervous or anxious
  • higher blood pressure
  • seizures (convulsions)
  • pass out (become unconscious or coma)

You will need to stay at the clinic where you receive the injection for at least 3 hours so your doctor can make sure you do not have symptoms of PDSS. When you leave the clinic someone must be with you. If you have symptoms of PDSS after you leave the clinic, get medical help or go to an emergency room right away.

2. Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis). Zyprexa Relprevv is not approved for treating psychosis in elderly people with dementia.

3. High blood sugar (hyperglycemia). High blood sugar can happen if you have diabetes already or if you have never had diabetes. High blood sugar could lead to:

  • a build up of acid in your blood due to ketones (ketoacidosis)
  • coma
  • death

Your doctor should do tests to check your blood sugar before you start taking Zyprexa Relprevv and during treatment. In people who do not have diabetes, sometimes high blood sugar goes away when Zyprexa Relprevv is stopped. People with diabetes and some people who did not have diabetes before taking Zyprexa Relprevv need to take medicine for high blood sugar even after they stop taking Zyprexa Relprevv.

If you have diabetes, follow your doctor's instructions about how often to check your blood sugar while taking Zyprexa Relprevv.

Call your doctor if you have any of these symptoms of high blood sugar (hyperglycemia) while taking Zyprexa Relprevv:

  • feel very thirsty
  • need to urinate more than usual
  • feel very hungry
  • feel weak or tired
  • feel sick to your stomach
  • feel confused or your breath smells fruity

4. High fat levels in your blood (cholesterol and triglycerides). High fat levels may happen in people treated with Zyprexa Relprevv, especially in teenagers (13 to 17 years old). Zyprexa Relprevv is not approved in patients less than 18 years old. You may not have any symptoms, so your doctor should do blood tests to check your cholesterol and triglyceride levels before you start taking Zyprexa Relprevv and during treatment.

5. Weight gain. Weight gain is very common in people who take Zyprexa Relprevv. Teenagers (13 to 17 years old) are more likely to gain weight and to gain more weight than adults. Zyprexa Relprevv is not approved in patients less than 18 years old. Some people may gain a lot of weight while taking Zyprexa Relprevv, so you and your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising.

What should I tell my healthcare provider before taking Zyprexa Relprevv?

  • heart problems
  • seizures
  • diabetes or high blood sugar levels (hyperglycemia)
  • high cholesterol or triglyceride levels in your blood

The symptoms of schizophrenia may include thoughts of suicide or of hurting yourself or others. If you have these thoughts at any time, tell your doctor or go to an emergency room right away.

Tell your doctor about all the medicines that you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Zyprexa Relprevv and some medicines may interact with each other and may not work as well, or cause possible serious side effects. Your doctor can tell you if it is safe to take Zyprexa Relprevv with your other medicines. Do not start or stop any medicine while taking Zyprexa Relprevv without talking to your doctor first.

  • Increased incidence of stroke or “mini-strokes” called transient ischemic attacks (TIAs) in elderly people with dementia-related psychosis (elderly people who have lost touch with reality due to confusion and memory loss). Zyprexa Relprevv is not approved for these patients.
  • Neuroleptic Malignant Syndrome (NMS): NMS is a rare but very serious condition that can happen in people who take antipsychotic medicines, including Zyprexa Relprevv.

  • Tardive Dyskinesia: This condition causes body movements that keep happening and that you can not control. These movements usually affect the face and tongue. Tardive dyskinesia may not go away, even if you stop taking Zyprexa Relprevv. It may also start after you stop taking Zyprexa Relprevv.
