A 36-year-old member asked:

is there a difference between ativan and klonopin (clonazepam)?

Yes: Both Ativan and Klonopin (clonazepam) are benzodiazepines and can be used to treat anxiety symptoms. Ativan is shorter-acting than Klonopin (clonazepam) though -- half-life of 8-24 hours compared to 19-60 hours.
Dr. Steven Reidbord

Similar & different: Both are "benzodiazepine" tranquilizers, which means they are chemically similar and relieve anxiety by their effect on GABA receptors in the brain. They are also both habit-forming if taken regularly. Comparing the two, Klonopin (clonazepam) is more sedating and lasts longer than the same dose of Ativan (lorazepam).

Yes and no.....: Same chemical class and both help with anxiety; but Klonopin (clonazepam) takes longer to get in your system and take effect and typically lasts longer but leaves your system more gradually, while Ativan gets in and out faster.

1/2 life: Ativan has quicker onset and excretion;whereas Klonopin (clonazepam) is longer to take effect and stays in body longer.

Ativan/klonopin: Ativan can last 4-6 hours, Klonopin (clonazepam) up to 12 hours. Also, Ativan can be injected and that is used in er for emergencies. There is a form of Klonopin (clonazepam) that works fast and can be dissolved on tongue, called Klonopin (clonazepam) wafers.

Duration of action &: One is short-acting, the other long-acting. One has greater risk of addiction than the other. One is metabolized in the liver, the other is not.

A 46-year-old member asked:

How can I substitute ativan to decrease klonopin (clonazepam) gradually ?

1 doctor answer3 doctors weighed in
Dr. Aaron Ament

Why?: Makes sense to decrease any psychoactive med gradually, and possibly substitution with Ativan - titrating dosage carefully - might turn out to give the same or better effect as the klonopin (clonazepam). More important: why alter klonopin (clonazepam)? Has it stopped working, are you taking too much? Review this carefully with the dr who prescribed it.

It is ignorance: You have a severe anxiety disorder. If this medication works for you then there is no "too high" about it. If you had diabetes and someone had you on 100 mg a day of insulin, would that necessarily be too much? Or asymptomatic TB on multiple antibiotics for six months? You do not abuse your meds. You take them as prescribed. You're in therapy and tried other options. You are entitled to quality of life. If others do not understand that then that is their problem.I daresay that more people have died in sleep of hypoglycemic reactions to their Insulin compared to the number who have died in their sleep from stopping breathing from benzodiazepines.

A 49-year-old male asked:

Would it be difficult to make a switch from 2.0 klonopin (clonazepam) to 2.5 ativan without much difficulty?

1 doctor answer1 doctor weighed in
Dr. Irving Harper
Internal Medicine 35 years experience
Guidance: It should not be difficult. Factors that will influence this include how long you have been on klonopin, (clonazepam) and the reason your doc chose Klonopin (clonazepam) in the first place. If you are on it for panic disorder than changing to Ativan would not be ideal. Same if it is being used for a seizure disorder. If anxiety, pretty easy. Check with your doc first , other medical conditions could effect switch.

What besides klonopin (clonazepam) is longer acting than Ativan? My ativan doesn't last long but works well otherwise. I want something Longer but hated klonopin (clonazepam)

Tranxene (clorazepate): Tranxene (clorazepate) is one of the longest acting benzodiazepines. It works well and seems to have less abuse potential because of the long half life.

A 31-year-old female asked:

How does klonopin (clonazepam) differ from Ativan in its intended effects, length of action, dosing frequency?

1 doctor answer2 doctors weighed in
Dr. Robert Grindstaff
Addiction Medicine 38 years experience
Both have similar: uses, anxiety, panic etc. The ativan has a 14 hour half life and klonopin (clonazepam) 20-50 hour half life both are used 2-3 times daily. Ativan being shorter acting will tend to be more addictive but both drugs have a high addiction potential.
