Klonopin vs. temazepam: What’s the difference?

What are Klonopin and temazepam?

Klonopin is a benzodiazepine anti-anxiety medication. Other benzodiazepines include alprazolam (Xanax), diazepam (Valium), lorazepam (Ativan), and flurazepam (Dalmane). Klonopin is mainly used to treat panic disorder, to prevent certain types of seizures, and to provide short-term relief of anxiety symptoms. Klonopin and other benzodiazepines enhance the effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain. Research shows that excessive activity in the brain may lead to anxiety or other psychiatric disorders.

Temazepam is a benzodiazepine used to treat anxiety and insomnia symptoms, such as trouble falling asleep or staying asleep. Temazepam is in the benzodiazepine class of drugs. Research shows that excessive activity in the brain may lead to anxiety or other psychiatric disorders, and that temazepam reduces the activity. Temazepam increases total sleep time.

What is the dosage of Klonopin vs. temazepam?


The dosage of Klonopin is tailored to the patient's needs.

  • For seizures in adults, the initial dose is 1.5 mg daily in 3 divided doses.
  • Dosage may be increased by 0.5 to 1 mg daily every 3 days until seizures are controlled or side effects preclude further increases in dose.
  • The maximum dose is 20 mg daily. The initial dose for panic disorders is 0.25 mg twice daily.
  • The dose may be increased to the target dose of 1 mg daily after 3 days.


  • The recommended dose of temazepam is 7.5 to 30 mg taken about 30 minutes prior to bedtime.
  • For elderly patients, start with 7.5 mg until the response is determined.

What drugs interact with Klonopin and temazepam?


Klonopin, like all other benzodiazepines, accentuates the effects of other drugs that slow the brain's processes — such as alcohol, barbiturates, and narcotics — and leads to increased sedation.


Alcohol or drugs that cause sleepiness increase the effects of temazepam.
