Overview Information on Clonazepam
Pharmacist Tip
Make sure your hands are dry before you take clonazepam if you take the dissolving tablet form.     
Clonazepam is an antianxiety medicine used to prevent and control epileptic seizures and treat panic attacks. Clonazepam comes as the brand name Klonopin®. It comes in tablet and dissolving tablet forms.

It is not completely understood how clonazepam works, but it is thought that clonazepam changes the way certain chemicals work in your brain, which slows down nerve activity. Your doctor will tell you how much clonazepam to take and how often to take it. Your doctor may change your dosage several times to find the one that works best for you.

You may take clonazepam with or without food. Store clonazepam at room temperature.

If you forget to take clonazepam, take it as soon as you can. If it's almost time for your next dose of clonazepam, skip the missed dose and take your next dose of clonazepam at the regularly scheduled time.

Over time, you can become physically dependent on clonazepam. Seizures, muscle cramping, tremors, vomiting, and sweating may happen if you quit clonazepam suddenly after taking it. Your doctor will gradually reduce your clonazepam dose.

Tell your doctor if you have any other medical conditions before taking clonazepam, including glaucoma, kidney or liver problems, lung or breathing problems, myasthenia gravis, or Parkinson's disease. Tell your doctor if you have alcohol or drug abuse problems. Also tell your doctor if you are pregnant, planning to become pregnant, or breast-feeding.

Clonazepam may cause drowsiness and dizziness. Do not drive or use machinery until you know how clonazepam will affect you.

Antiepileptic medicines, including clonazepam, may cause suicidal thoughts in some people. Tell your doctor right away if you start to have suicidal thoughts or mood changes when you take clonazepam.

Call your doctor right away if you have any of the following symptoms or if they are new, getting worse, or are worrying you:

  • New or worse depression
  • Thoughts about suicide or dying, or attempts to commit suicide
  • New or worse anxiety
  • Feeling very agitated or restless
  • Panic attacks
  • Trouble sleeping
  • New or worse irritability
  • Acting aggressive, or being angry or violent
  • Acting on dangerous impulses
  • An extreme increase in activity and talking
  • Other unusual changes in behavior or mood
Call your doctor or seek emergency help if you suffer an allergic reaction to clonazepam, including hives or itching; swelling in your face, hands, mouth, or throat; trouble breathing; or chest tightness.

While taking clonazepam, contact your doctor immediately if you have any of the following side effects:

  • Changes in vision
  • Confusion
  • Depression
  • Hallucinations
  • Mood changes, excitability, or aggressive behavior
  • Movement difficulty, staggering, or jerky movements
  • Muscle cramps or weakness
  • Tremors
  • Unusual eye movements
Common side effects of clonazepam you may notice include:

  • Dry mouth or drooling
  • Blurred vision or headache
  • Dizziness or drowsiness
  • Difficulty sleeping or nightmares
  • Nausea, constipation, or diarrhea
Let your doctor know if any of these side effects get worse or don't go away while taking clonazepam.
