trigeminal neuralgia
"After being on regular Tegretol for about a year in combination with Neurontin, my Neuro changed it to the Tegretol XR with fantastic results.  I have been taking this for about 2 years now and other than the annoying side effects and occasional breakthrough pain I am very happy.  Be warned though that the new generic of Tegretol XR may not be as effective as the name brand. When the generic came out my insurance automatically switched me and they didn't work near as well and I was having a lot of breakthrough pain.  My Dr had to make a request to my insurance for the name brand and thankfully they approved it."
