Warning

  • This drug is a benzodiazepine. The use of a benzodiazepine drug along with opioid drugs has led to very bad side effects. Side effects that have happened include slowed or trouble breathing and death. Opioid drugs include drugs like codeine, oxycodone, and morphine. Opioid drugs are used to treat pain and some are used to treat cough. Talk with the doctor.
  • If your child is taking this drug with an opioid drug, get medical help right away if your child feels very sleepy or dizzy; if your child has slow, shallow, or trouble breathing; or if your child passes out. Get medical help right away if your child does not respond, does not answer or react like normal, or will not wake up.
  • Benzodiazepines can put your child at risk for addiction, abuse, and misuse. Misuse or abuse of this drug can lead to overdose or death, especially when used along with certain other drugs, alcohol, or street drugs. Addiction can happen even if your child takes this drug as told by the doctor. Get medical help right away if your child has changes in mood or behavior, suicidal thoughts or actions, seizures, or trouble breathing.
  • Your child will be watched closely to make sure your child does not misuse, abuse, or become addicted to this drug.
  • Benzodiazepines may cause dependence. Lowering the dose or stopping this drug all of a sudden may cause withdrawal. This can be life-threatening. The risk of dependence and withdrawal are raised the longer your child takes this drug and the higher the dose. Talk to the doctor before you lower the dose or stop giving this drug. You will need to follow the doctor’s instructions. Get medical help right away if your child has trouble controlling body movements, seizures, new or worse behavior or mood changes like depression or thoughts of suicide, thoughts of harming someone, hallucinations (seeing or hearing things that are not there), losing contact with reality, moving around or talking a lot, or any other bad effects.
  • Sometimes, withdrawal signs can last for several weeks to more than 12 months. Tell the doctor if your child has anxiety; trouble with memory, learning, or focusing; trouble sleeping; burning, numbness, or tingling; weakness; shaking; muscle twitching; ringing in the ears; or any other bad effects.
