for
Neurontin,
and see what it says, there are several good drug sites, like the rxlist.com one I gave,
and also drugs.com is same thing. If you have good insurance, you could switch over to Lyrica, a cousin to Neurontin, you take less mg, yet it's more powerful, with less side effects, but it's expensive. But keep in mind, with all those GABA type drugs, the dose has to be increased until you reach a plateau, usually within a few months of beginning it.
