How does this medication work? What will it do for me?
Clonazepam belongs to the class of medications called benzodiazepines.
In general, benzodiazepines are used as a sedative or to decrease seizures
or anxiety.
Clonazepam is used to treat seizure disorders. It helps by slowing
the activity of the nerves in the brain (i.e., the central nervous system).
Your doctor may choose to use this medication for conditions other than the
ones listed in these drug information articles. If you are unsure why you
are taking this medication, contact your doctor.
How should I use this medication?
The recommended adult starting dose of clonazepam ranges from 0.5 mg to 2 mg daily in divided doses, with or without food. It is important that the dose be individualized to your specific needs to avoid excessive sedation or motor impairment. Your doctor may increase this dose to as high as 20 mg per day in two to four divided doses. The dose is usually started low and increased if necessary by your doctor.
Children who are more than 10 years old or who weigh more than 30 kg have their doses based on weight (0.01 mg per kg of body weight per day - 0.03 mg per kg of body weight per day) and need to be monitored carefully.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way that you are taking the medication without consulting your doctor.
Clonazepam may be habit forming when taken for long periods of time. If you have been taking this medication regularly for a long period of time (i.e., more than one month), do not stop taking the medication without speaking with your doctor. To avoid withdrawal effects, a gradual reduction in dose is recommended when stopping this medication.
It is important that this medication be taken exactly as prescribed by the doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If your next dose is in less than 4 hours, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
