KLONOPIN® (KLON-oh-pin)
(clonazepam)
Tablets and Wafers
CIV

Read this Medication Guide before you start taking KLONOPIN and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.

KLONOPIN can cause serious side effects. Because stopping KLONOPIN suddenly can also cause serious problems, do not stop taking KLONOPIN without talking to your healthcare provider first.

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

Do not stop taking KLONOPIN without first talking to your healthcare provider. Stopping KLONOPIN suddenly can cause serious problems.

KLONOPIN can cause serious side effects, including:

1. KLONOPIN can slow your thinking and motor skills

• Do not drive, operate heavy machinery, or do other dangerous activities until you know how KLONOPIN affects you.
• Do not drink alcohol or take other drugs that may make you sleepy or dizzy while taking KLONOPIN until you talk to your healthcare provider. When taken with alcohol or drugs that cause sleepiness or dizziness, KLONOPIN may make your sleepiness or dizziness worse.

2. Like other antiepileptic drugs, KLONOPIN may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

Call a 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
• attempt 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.
    
    Do not stop KLONOPIN without first talking to a healthcare provider.
    
    Stopping KLONOPIN suddenly can cause serious problems. Stopping KLONOPIN suddenly can cause seizures that will not stop (status epilepticus).

3. KLONOPIN may harm your unborn or developing baby.

• If you take KLONOPIN during pregnancy, your baby is at risk for serious birth defects. These defects can happen as early as in the first month of pregnancy, even before you know you are pregnant. Birth defects may occur even in children born to women who are not taking any medicines and do not have other risk factors.
• Children born to mothers receiving benzodiazepine medications (including KLONOPIN) late in pregnancy may be at some risk of experiencing breathing problems, feeding problems, hypothermia, and withdrawal symptoms.
• Tell your healthcare provider right away if you become pregnant while taking KLONOPIN. You and your healthcare provider should decide if you will take KLONOPIN while you are pregnant.
• If you become pregnant while taking KLONOPIN, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry. You can register by calling 1-888-233-2334. The purpose of this registry is to collect information about the safety of antiepileptic drugs during pregnancy.
• KLONOPIN can pass into breast milk. Talk to your healthcare provider about the best way to feed your baby if you take KLONOPIN. You and your healthcare provider should decide if you will take KLONOPIN or breast feed. You should not do both.

4. KLONOPIN can cause abuse and dependence.

• Do not stop taking KLONOPIN all of a sudden. Stopping KLONOPIN suddenly can cause seizures that do not stop, hearing or seeing things that are not there (hallucinations), shaking, and stomach and muscle cramps.
  • Talk to your doctor about slowly stopping KLONOPIN to avoid getting sick with withdrawal symptoms.
  • 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.

KLONOPIN is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep KLONOPIN in a safe place to prevent misuse and abuse. Selling or giving away KLONOPIN may harm others, and is against the law. Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.
