What is the most important information I should know about Libervant?

Libervant is a benzodiazepine medicine. Taking benzodiazepines with opioid medicines, alcohol, or other central nervous system (CNS) depressants (including street drugs) can cause severe drowsiness, breathing problems (respiratory depression), coma, and death. Get emergency help right away if any of the following happens:

• shallow or slowed breathing,
• breathing stops (which may lead to the heart stopping),
• excessive sleepiness (sedation).

Do not allow your child to drive a motor vehicle, operate heavy machinery, or ride a bicycle until you know how taking Libervant with opioids affects your child.

Risk of abuse, misuse, and addiction. Libervant is used in children 2 to 5 years of age. The unapproved use of Libervant has a risk for abuse, misuse, and addiction, which can lead to overdose and serious side effects including coma and death.

• Serious side effects including coma and death have happened in people who have abused or misused benzodiazepines, including diazepam (the active ingredient in Libervant). These serious side effects may also include delirium, paranoia, suicidal thoughts or actions, seizures, and difficulty breathing. Call your child’s healthcare provider or go to the nearest hospital emergency room right away if you get any of these serious side effects.
• Your child can develop an addiction even if your child takes Libervant as prescribed by your child’s healthcare provider.
• Give Libervant exactly as your healthcare provider prescribed.
• Do not share Libervant with other people.
• Keep Libervant in a safe place and away from children.

Physical dependence and withdrawal reactions. Libervant is intended for use if needed in order to treat higher than usual seizure activity. Benzodiazepines, including Libervant, can cause physical dependence and withdrawal reactions, especially if used daily. Libervant is not intended for daily use.

• Do not suddenly stop giving Libervant to your child without talking to your child’s healthcare provider. Stopping Libervant suddenly can cause serious and life-threatening side effects, including, unusual movements, responses, or expressions, seizures that will not stop (status epilepticus), sudden and severe mental or nervous system changes, depression, seeing or hearing things that others do not see or hear, homicidal thoughts, an extreme increase in activity or talking, losing touch with reality, and suicidal thoughts or actions. Call your child’s healthcare provider or go to the nearest hospital emergency room right away if your child gets any of these symptoms.
• Some people who suddenly stop benzodiazepines have symptoms that can last for several weeks to more than 12 months including, anxiety, trouble remembering, learning, or concentrating, depression, problems sleeping, feeling like insects are crawling under your skin, weakness, shaking, muscle twitching, burning, or prickling feeling in your hands, arms, legs or feet, and ringing in your ears.
• Physical dependence is not the same as drug addiction. Your child’s healthcare provider can tell you more about the differences between physical dependence and drug addiction.
• Do not give your child more Libervant than prescribed or give Libervant more often than prescribed.

Libervant can make your child sleepy or dizzy and can slow your child’s thinking and motor skills.

• Do not allow your child to drive a motor vehicle, operate machinery, or ride a bicycle until you know how Libervant affects your child.
• Do not give other drugs that may make your child sleepy or dizzy while taking Libervant without first talking to your child’s healthcare provider. When taken with drugs that cause sleepiness or dizziness, Libervant may make your child’s sleepiness or dizziness much worse.

Like other antiepileptic medicines, Libervant may cause suicidal thoughts or actions in a small number of people, about 1 in 500.

Call a healthcare provider right away if your child has any of these symptoms, especially if they are new, worse, or worry you:

• thoughts about suicide or dying
• new or worse depression
• feeling agitated or restless
• trouble sleeping (insomnia)
• acting aggressive, being angry or violent
• other unusual changes in behavior or mood
• attempts to commit suicide
• new or worse anxiety or irritability
• an extreme increase in activity and talking (mania)
• new or worse panic attacks
• acting on dangerous impulses

Pay attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings.

Keep all follow-up visits with your child’s healthcare provider as scheduled.

Call your child’s healthcare provider between visits as needed, especially if you are worried about symptoms. Suicidal thoughts or actions can be caused by things other than medicines. If your child has suicidal thoughts or actions, your child’s healthcare provider may check for other causes.
