My daughter was on Nortriptyline, but had bad side effects. They are switching her to neurontin as soon as we get all the Nortriptyline out of her system. If you can tolerate it, the Drs tell me that Nortriptyline can be very effective - if the neurontin doesn't work for your son. Advil doesn't do anything for us. How long has he been on the neurotin?
