The symptoms of a clonazepam overdose vary, but can include slow reflexes, confusion, drowsiness, and a coma. The specific overdose symptoms a person experiences will depend on how much clonazepam was taken and whether it was combined with alcohol or other drugs. Treatment for a clonazepam overdose will depend on how recent the overdose was. Possible options include medications, "pumping the stomach," and supportive care.
Clonazepam (Klonopin®) is part of a group of medications known as benzodiazepines. It is approved to treat panic disorder and certain types of seizures. As with all medications, it is possible for a person to overdose on clonazepam. The particular effects of a clonazepam overdose can vary, depending on a number of factors, including the clonazepam dosage and whether it was taken with any other medicines, street drugs, or alcohol.
If a person overdoses on clonazepam, the symptoms can vary. Some commonly reported symptoms of a clonazepam overdose include:
- Slow reflexes
Life-threatening overdose symptoms are more likely if clonazepam is combined with alcohol or other medications.
The treatment for a clonazepam overdose will vary. If the clonazepam overdose was recent, the healthcare provider may use certain medicines or place a tube into the stomach to "pump the stomach." Flumazenil (Romazicon®), an antidote for a benzodiazepine overdose, may also be helpful (although this treatment can be dangerous in people taking clonazepam for seizures). Treatment also involves supportive care, which consists of treating the symptoms that occur as a result of the overdose. For example, supportive treatment options may include:
- Fluids through an intravenous line (IV)
- Careful monitoring of blood pressure, heart rate, and breathing
- Other treatments based on the complications that occur.
It is important that you seek medical attention immediately if you believe that you may have overdosed on clonazepam.
