Generic name: clobazam

What is Onfi?

Onfi is a prescription medicine used along with other medicines to treat seizures associated with Lennox-Gastaut syndrome in people 2 years of age or older.

It is not known if Onfi is safe and effective in children less than 2 years old.

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

  • Do not stop taking Onfi without first talking to your healthcare provider. Stopping Onfi suddenly can cause serious side effects.
  • Onfi is a benzodiazepine medicine. Benzodiazepines can cause severe drowsiness, breathing problems (respiratory depression), coma, and death when taken with opioid medicines.
  • Onfi can make you sleepy or dizzy and can slow your thinking and motor skills. This may get better over time.
    • Do not drive, operate heavy machinery, or do other dangerous activities until you know how Onfi affects you.
    • Onfi may cause problems with your coordination, especially when you are walking or picking things up.
  • Do not drink alcohol or take other drugs that may make you sleepy or dizzy while taking Onfi until you talk to your healthcare provider. When taken with alcohol or drugs that cause sleepiness or dizziness, ONFI may make your sleepiness or dizziness much worse.
  • Onfi can cause withdrawal symptoms.
    • Do not stop taking Onfi all of a sudden without first talking to a healthcare provider. Stopping Onfi suddenly can cause seizures that will not stop (status epilepticus), hearing or seeing things that are not there (hallucinations), shaking, nervousness, and stomach and muscle cramps.
    • Talk to your healthcare provider about slowly stopping ONFI to avoid withdrawal symptoms.
  • Onfi can be abused and cause dependence.
    • Physical dependence is not the same as drug addiction. Your healthcare provider can tell you more about the differences between physical dependence and drug addiction.
  • Onfi is a federally controlled substance (CIV) because it can be abused or lead to dependence. Keep Onfi in a safe place to prevent misuse and abuse. Selling or giving away Onfi may harm others, and is against the law. Tell your healthcare provider if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.
  • Serious skin reactions have been seen when ONFI is taken with other medicines and may require stopping its use. Do not stop taking Onfi without first talking to your healthcare provider.
    • A serious skin reaction can happen at any time during your treatment with Onfi, but is more likely to happen within the first 8 weeks of treatment. These skin reactions may need to be treated right away.
    • Call your healthcare provider immediately if you have skin blisters, rash, sores in mouth, hives or any other allergic reaction.
  • Like other antiepileptic drugs, Onfi may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

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

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

How can I watch for early symptoms of suicidal thoughts and actions?

  • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
  • Keep all follow-up visits with your healthcare provider as scheduled.

Call your 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 you have suicidal thoughts or actions, your healthcare provider may check for other causes.

You can register by calling 1-888-233-2334. For more information about the registry go to http://www.aedpregnancyregistry.org. The purpose of this registry is to collect information about the safety of antiepileptic drugs during pregnancy.
  • Onfi can pass into breast milk. Talk to your healthcare provider about the best way to feed your baby if you take ONFI. You and your healthcare provider should decide if you will take Onfi or breast feed. You should not do both.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking Onfi with certain other medicines can cause side effects or affect how well Onfi or the other medicines work. Do not start or stop other medicines without talking to your healthcare provider.
