Clonazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen) that is used to treat certain seizure disorders (including absence seizures or Lennox-Gastaut syndrome) in adults and children.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Clonazepam can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing. A person caring for you should seek emergency medical attention if you have weak or shallow breathing, if you are hard to wake up, or if you stop breathing.
Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.

- weak or shallow breathing;
- unusual changes in mood or behavior;
- nightmares, hallucinations;
- thoughts of suicide or hurting yourself;

Common side effects may include:
- drowsiness, dizziness;
- feeling tired or depressed;
- memory problems; or
- problems with walking or coordination.
