Klonopin (clonazepam) is from a class of medicines called benzodiazepines, which belong to the group called central nervous system (CNS) depressants. Its mechanism of action is not fully understood, but it is believed that clonazepam has the capacity to enhance the activity of the major inhibitory neurotransmitter in the central nervous system, slowing it down.1 Clonazepam’s primary use is for seizures and panic attacks but it is sometimes used to treat tremor and occasionally used to manage pain or spasticity when other medicines don’t work.2

Some of the side effects that clonazepam may cause are: drowsiness, problems with walking and coordination, dizziness, depression, fatigue and problems with memory. 3

Clonazepam has a black box warning (information that appears on a prescription drug’s label and is designed to call attention to serious or life-threatening risks4) concerning use with same class medicines, which may result in profound sedation, breathing difficulties, depression, coma, and death.1

Klonopin is also available as a generic medicine.5
