Benzos for drug induced seizures?

My pdoc suggested to add clobazam to my clozapine for fixing seizure induced by clozapine.

I have read benzos are not good for long term treatment of epilepsy as it can develop tolerance.

Other option he suggested was to try sodium valproate controlled release, which I’m taking right now.

Should i switch from valproate to benzo ? What should i do ? I’m looking for an effective long term epilepsy med with least side effects.
