Both lithium and valproate have been reported to increase rat CSF GABA levels. Regarding valproate, animal studies reported that it enhances GABA levels, GABA synaptic release, GAD activity, neuronal GABA responsiveness, and inhibits GABA-T in several brain regions.
While tapering from valium, I want to make sure that if I take flexeril that I'm not adding to the benz's and that it is not the same type of drug that works on your gaba receptors, etc. Lately I've had a lot of pain and want to take a flexeril, but will not touch it if it will in any way affect my tapering of valium.rom what I have read after a precursory Net search, it does not affect the GABA receptors. But this might be a good time to call a pharmacist just to find out for sure. Tell them that you're tapering your benzo because you're dependent and you're wondering how Flexeril would affect you in such a situation.
