In this session, we will be discussing the consumer medication information for clonazepam, trade name KlonopinTM.

What it’s for & How to take

Clonazepam acts on the brain and nerves in the brain to produce a calming effect. It does this by enhancing a chemical in the brain which decreases excitement.

Clonazepam is used to prevent and control seizures. Clonazepam is also used to treat panic disorder, anxiety, restless leg syndrome, and nerve pain.

Clonazepam is usually prescribed to be taken not more than three times daily; however, your doctor will adjust your dose based upon how you respond to treatment. This medication may be taken with or without food.

If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Do not increase your dose of clonazepam or take it more often than ordered without your doctor’s approval because this drug can be habit-forming.

If you have taken this medication for a long time, you may notice that it doesn’t seem to work as well. Contact your doctor to discuss your options. If you have taken this medication for a long time or in a high dose, do not stop taking it all at once because it may cause a withdrawal reaction. Your doctor may have you decrease your dose of clonazepam over a couple weeks or months.
