Do not take LYBALVI if you are taking opioids or are experiencing acute opioid withdrawal.
LYBALVI may cause serious side effects, including:
-
Stroke (cerebrovascular problems) in elderly people with dementia-related psychosis that can lead to death.
-
Opioid withdrawal. Do not
take LYBALVI for at least 7 days after you stopped taking short-acting opioids and for at least 14 days after you stopped taking long-acting opioids. One of the medicines in LYBALVI (samidorphan) can cause opioid withdrawal that may be severe and cause hospitalization in people who are physically dependent on opioids. Talk to your healthcare provider if you have questions about the type of opioid you take.
-
Risk of life-threatening opioid overdose.
You should not start taking opioids for at least 5 days after you stop treatment with LYBALVI. One of the medicines in LYBALVI (samidorphan) can increase your chance of having an opioid overdose that can cause death if you take opioids during treatment or within 5 days after stopping treatment with LYBALVI.
- You can accidentally overdose in 2 ways:
- LYBALVI blocks the effects of opioids, such as heroin, methadone, or opioid pain medicines.
Do not
take large amounts of opioids to try to overcome the opioid-blocking effects of LYBALVI. This can lead to serious injury, coma, or death.
- After you take LYBALVI, its blocking effect slowly decreases and completely goes away over time. You may be more sensitive to the effects of opioids. If you have used opioid street drugs or opioid-containing medicines in the past, using opioids in amounts that you used before treatment with LYBALVI can lead to overdose or death.
- It is important that you tell your family and the people closest to you of this increased sensitivity to opioids and the risk of overdose.
-
You or someone close to you should get emergency medical help right away if you:
- have trouble breathing
- become very drowsy with slowed breathing

- feel faint, very dizzy, confused, or have unusual symptoms
- Tell your healthcare provider if you are taking LYBALVI before a medical procedure or surgery.
-
Neuroleptic malignant syndrome (NMS), a serious condition that can lead to death.

- high fever
- stiff muscles
- confusion
- sweating
- changes in your breathing, pulse, heart rate, and blood pressure
-
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS):
One of the medicines in LYBALVI (olanzapine) can cause DRESS, which can cause death. Tell your healthcare provider right away if you develop any of the following symptoms of DRESS, including:
- rash
- swollen glands
- liver problems
- heart problems
- fever
- kidney problems
- lung problems
-
Problems with your metabolism such as:

high blood sugar (hyperglycemia) and diabetes.
Increases in blood sugar can happen in some people who take LYBALVI. Extremely high blood sugar can lead to coma or death. Your healthcare provider should check your blood sugar before you start and regularly during treatment with LYBALVI.

- feel very thirsty

-
Uncontrolled body movements (tardive dyskinesia).
LYBALVI may cause movements that you cannot control in your face, tongue, or other body parts. Tardive dyskinesia may not go away, even if you stop taking LYBALVI. Tardive dyskinesia may also start after you stop taking LYBALVI.
-
Decreased blood pressure (orthostatic hypotension) and fainting.
You may feel lightheaded or faint when you rise too quickly from a sitting or lying position.
-
Falls.
LYBALVI may make you sleepy or dizzy, may cause a decrease in your blood pressure when changing position (orthostatic hypotension), and can slow your thinking and motor skills, which may lead to falls that can cause fractures or other injuries.
-
Low white blood cell count.
Your healthcare provider may do blood tests during the first few months of treatment with LYBALVI.
-
Difficulty swallowing
that can cause food or liquid to get into your lungs.
