Can you use Buspar to get off Klonopin?

Sadly no you can't. Buspar have a totally different mechanism of action than Klonopin. They are not interchangeable.

I'm also on Klonopin since 2005. The only way I was able to reduce my dose was to gradually reducing the dose over years. I was at 10 mg a day at one point of my life and now I'm on 2.25 mg a day of Klonopin.

Each cut I make in the dose is hard, reducing by 0.25 mg take months for me to get used to the new lower dose and feel stable.

For the anxiety, I think it's your Trazodone. Usual dose for sleep is 50 mg... Why are you on 150 mg? Also the Trazodone is metabolized in an active metabolite who have potent stimulating effects and can lead to anxiety especially the morning after you take your dose before bedtime.

If you need some help, talk to your doctor and work on a very slow tapering schedule of your Klonopin dose. It's the only way to reduce your Klonopin dose and be free of it.

I have had adverse reactions to trazodone. It made me have insomnia with a hangover effect in return caused anxiety. It had to be paired with another drug that reduced its ill effects.
Buspar, on the other hand- works great for anxiety and panic but, it won’t prevent withdrawal effects with benzodiazepines- you need to wean off slowly in order to avoid the risk of seizures and rebounding panic not to mention the hell of withdrawal. Topamax is very helpful it also prevents seizures and clonidine is calming and helps with blood pressure as well as many other ailments like fight or flight response all are helpful when, weaning off benzodiazepines & can be used together.
Unlike, the dangers with benzodiazepines buspar, is one of the safest drugs that- is actually, manufactured to treat anxiety.
It’s how your body tolerates the medication and how sensitive you are to benzodiazepines and the weaning process.
I wish you the best of luck as I am weaning off benzodiazepines again myself.

The answer is yes and no. I've tried it before with no success but have heard that it works for some. I suppose if you slowly weaned yourself off the Klonopin while taking the Buspar it could work. My experience didn't work because I tried quitting Klonopin pretty much cold turkey and the Buspar did literally nothing to stop my anxiety mainly because Buspar is sort of like an SSRI in that it has to build in your system for a few days to become effective and didn't help with my immediate anxiety from stopping Klonopin abruptly. So if you had a more planned approach I suppose it could work.
