Klonopin

Klonopin may be prescribed to treat several conditions, including various types of epileptic seizures and panic disorder. As part of a group of medications called benzodiazepines, the drug works by enhancing the naturally calming effect of a certain brain chemical. It is available in the form of a tablet and orally disintegrating tablets, and is usually taken two or three times a day. Drowsiness, coordination problems, and behavior problems are some of the common side effects seen with Klonopin.

 

What Is Klonopin?

Klonopin® (clonazepam) is a prescription medication approved to treat the following conditions:
 

 

    • Seizures associated with Lennox-Gastaut syndrome (a severe form of epilepsy)
    • Akinetic seizures (also known as atonic seizures), which are characterized by a sudden loss of muscle tone, causing "drop attacks"
    • Myoclonic seizures, which are characterized by sudden, brief muscle jerks
    • Absence seizures, which are characterized by brief periods of decreased awareness or "spacing out."

How Does It Work?

Klonopin is part of a group of medications called benzodiazepines. Benzodiazepines have various effects on the body, including:
 
  • Reducing anxiety
  • Causing sleepiness
  • Relaxing muscles
  • Stopping seizures
  • Impairing short-term memory.
     
All benzodiazepines can have these effects to some degree, depending on the specific benzodiazepine that is being taken. They work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA), a brain chemical that is naturally calming. GABA can slow down or stop certain nerve signals in the brain. This is why Klonopin and other benzodiazepines are known as mild tranquilizers, sedatives, or central nervous system depressants (CNS depressants).
 

When and How to Take Klonopin

Some general considerations for when and how to take it include the following:
 
  • The medication comes in tablets and wafers (orally disintegrating tablets). It is taken by mouth, usually two or three times daily.
     
  • Klonopin wafers will rapidly dissolve in your mouth, without any need for water.
     
  • The medication can be taken with or without food. If it bothers your stomach, try taking it with food.
     
  • For the medication to work properly, it must be taken as prescribed. It may cause serious problems if you take it in higher dosages or for a longer period of time than your healthcare provider recommends (see Klonopin Addiction).
     

Dosing Information

The dosage that your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • The medical condition being treated
  • Your age
  • Other medications you may be taking
  • Other medical conditions you may have.
     
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
