Klonopin Overdose
Overdosing on clonazepam alone is rarely fatal. Abusing this medication along with other drugs such as alcohol or painkillers can produce dangerous interactions that can lead to serious harm or death.
Signs and symptoms of an overdose may include:
- Drowsiness
- Confusion
- Impaired coordination
- Slow reflexes
- Slowed or stopped breathing
- Coma (loss of consciousness)
- Death

Clonazepam, like other benzodiazepines, slows the body’s systems, so people who overdose may stop breathing. It is important to maintain breathing to ensure minimum damage or death. Call 911 for assistance.
