Clonazepam is used on its own or together with other medicines to treat epilepsy (also known as fits or seizures).
Clonazepam may also be used to treat other conditions as decided by your doctor, such as panic disorder.
Take Clonazepam exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
Depending on your condition, your doctor may prescribe Clonazepam for regular use or when required.
For the treatment of seizures, Clonazepam must be taken regularly for it to be effective. Continue taking Clonazepam even when you feel better. Clonazepam is not a cure and you may need to take it long-term to keep your seizures under control. Do not stop taking Clonazepam unless instructed by your doctor as stopping it suddenly may worsen your condition.
Clonazepam may be taken with or without food.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
If you often forget to take your medicine, let your doctor and pharmacist know.
Alert your doctor if you have the following:
- liver disease
- history of alcohol dependence
- severe breathing difficulties
as Clonazepam may not be suitable for you.

- muscle weakness disorder called myasthenia gravis
